How can old mechanical disc rival modern hydraulic brakes! - TRP HY/RD

[@jonathangreen7111]

In this whole discussion surely riding conditions must be mentioned. I run TRP Spyre cable discs on my winter bike. The bike is mainly ridden in the steep hills of the Peak District and on crappy, wet, gravelly lanes. In my experience they are MUCH better than rim brakes in these conditions. They are also not wearing out my rims. I used to get through a pair of rims every 2 years. These brakes meant I could use my perfectly serviceable old mechanical groupset. They are also SO MUCH MORE easily serviceable than the hydros on my gravel bike. Great video and thanks for talking about stuff that virtually all other youtubers ignore. Keep up the good work.

[@gregsus4536]

Thanks for mentioning the TRP Spyre cable disc brakes. I’ve been using them on my gravel bike for five years with the same, positive experience. Good braking performance, easily serviced and reliable.

[@rockkin09]

I have them on two of my bikes and they just work. For my road bike one of the reasons I got them is you can adjust each caliper independently and avoid that rub that you can't always get rid of with hydros. Warped discs happen, dirt happens and when I'm out riding 200 miles I would rather not hear it rubbing all day!

[@3CityRide]

What the... Spyres are easy to service and easier than hydraulic ones? If you really use them in harsh conditions you mentioned you definitely should disassembly the Spyre calipers itself due the fact that there are bearings inside of them. Getting inside it's a quite unique experience and I would not call it "easier serviceable" than any hydraulic brakes. Especially with the fact - what do you want to service on hydraulic brakes? O.o

[@paulboomerterry]

love my HY/RD on my Whytes Road bike. Done 1000's of miles only changed the pads once, never serviced the mechanism just changed the brake cables. Close in performance strength to full hydraulic breaks but still has the modulation of hydraulic feel. What I like is you can adjust them like your old cables systems. 😃

[@uvwuvw-ol3fg]

Only disadvantage is bleed plug hex screw has the same size as pad bolt and they are so close together it's easy to accidentally unscrew the wrong one requiring bleeding. Also they often start to feel spongy after bike has accidentally tipped over for less than a minute. Previous bleed procedure took six hours to get the bubbles out.

[@richfox1255]

I put about 6,000 miles of hilly, messy, wet riding on a set of the Hy/Rd calipers a few bikes back in the Pacific Northwest (Oregon). Happy with the performance, zero maintenance issues. A great solution for folks looking for the benefits they offer.

The HY/RD episode! I bought a trek domane back in 2015 and it came with these brakes. They have always performed very well. I recently tried to upgrade to full hydro ultegra 8000. What a pain! I should have left the HY/RDs alone. I have to put them back on the bike.

[@domain-user]

I've had these brakes TRP HY/RD on my bike since 2019 along with a SRAM Force 1 groupset. Actually, despite being hybrids, their reaction time to braking is very good and really strong. Fun fact, it's very hard to find reviews on them, because of that, not all mechanics are used to working with them either

[@qwertyazerty2137]

No wonder - if they are almost as good as fully hydro systems and the industry have been marketing aggresively for fully hydros, we can suspect that it made sure that no influencer or media outlet that are on their payroll, received them for a review.

[@valentinszabo4331]

Thanks for ur comment . Considered buying a new sram apex hydro lever - but the cost is still high - found this caliper for € 70 / disc incl. - think id rather " upgrade" the spyre caliper to this hy/ dr stuff

[@Rafskat]

On the note of that expansion chamber.. Shimano road hydraulic disc brakes have also dedicated expansion chamber.. so two expansion chambers per one system. I don't know if anybody else does it. For mechanical in general.. Good mechanical disc brake calipers like Paul Klampers, Growrac equal.. are very good, but also very pricey. But.. they are perfect for some touring/expedition rigs, because they are so simple and you can work on them, change cable etc.. and I'm a mechanic and still I don't want to be stuck in the middle of nowhere with for example.. oil leak.. because Murphy's law

[@Metal-Possum]

My touring bike is on cantilevers, I barely use the brakes when touring anyway.

[@Rafskat]

@@Metal-Possum If the frame supports it, great. Rim brakes can be good, cantilevers included. Just adjust them properly and use good pads

[@CanIHasThisName]

I do all my own maintenance and hydraulic brakes are easier to maintain while requiring less maintenance. "I don't want to be stuck in the middle of nowhere with for example.. oil leak" This used to be a concern for some people in the early days, but hydraulic braking systems have proven to be more reliable than mechanical ones and they have much longer service cycles. Today there's just no reason to hold this sentiment anymore, especially since it's more work to have and maintain mechanical brakes. I used to have mechanical brakes on my gravel bike, did over 10K on them. Due to not being self-adjusting, needing to adjust pad position was a very common thing, especially after a few hilly rides. They also require a special braking cable housing to maintain braking power and these have gotten very hard to get now. Being able to replace a cable isn't an advantage. You can just as well replace fluid or a hose on the go, you just need different equipment for it. You need proper cutters to cleanly cut brake cable housings, whereas brake hoses can be cut with a small sharp knife. Brake hoses are lighter and can be coiled into a smaller package. And if you're still paranoid about cutting a hose, you can get hoses with metal sleeves.

[@quasimal]

Shout-out to Growtac disc brakes. Fantastic mechanical brakes that have near 0 risk of overheating unlike even the most premium mech-hydro brakes.🙂

[@mattlloyd6651]

I've put a few thousand miles on my HY/RD brakes and they've been amazing. A lot of those miles have been on rather steep gravel roads. I had a little trouble setting the pull range on them but otherwise, they were a cinch to install too.

[@mattherbert9027]

Love your enthusiasm Luke, main reason why I watch, plus you always learn something 👍

[@tahoeclimber]

Bought the TRP HY/RDs simply because the idea of moving the reservoir away from the lever and to the brakes made sense and seemed easier to work on. Love em! You're only losing some power in the flex of the cables but it's a road bike, you don't need insane single finger braking power

[@nubee.pkunite]

that's why compressionless cable set is the best partner for this, 90% hydraulic feels and the modulation is there. worth it

[@FurySpyder]

I still choose cable discs over hydraulic on my commuting/winter/touring bikes for two reasons you haven't mentioned.... 1. Hydraulic fluid is hygroscopic so I used to find I had to constantly service hydraulic brakes when used regularly in UK winter (ie wet!) conditions to let out a bit of fluid to prevent over-filling and then replace the fluid as eventually the water content would lead to corrosion internally. You get none of this with cable discs which are generally more robust. 2. The UK winter roads are usually wet AND gritty/muddy. Hydraulic discs run with minimal pad to disc clearance (though the latest Shimano 12 speed ones are much better) so in such conditions you constantly get debris between the pad and disc, until you brake to clean it up. With cable discs however, and mostly I use TRP Spyre or Spyre SLC's, you can individually adjust the clearance of each pad, so at the start of winter I open up the clearance slightly to prevent 'rub' in gritty conditions. I also have a set of Hy-Rd's and they are awesome - the feel of a full hydraulic but allowing you to use a mechanical groupset. As you say though they are a bit heavy and on the rear you have to be really careful with clearance as many frames, especially smaller frames, cannot accommodate them. For my 'best'/summer bike I still prefer the overall performance of full hydraulics but I can lock up a tyre with my rim brake bike just as easily as I can with the cable discs and just as easily as I can with the hydraulics... It's just the lever/finger load that changes.

[@Rossingiol]

Only DOT fluid is hygroscopic, and that is by design. Mineral oil as used by Shimano is hydrophobic.

[@FurySpyder]

@@Rossingiol true, yes. My problems in the past were with SRAM hydraulics, but in general, due to reliance on close fitting pistons etc, I find any hydraulic brakes a bit less robust to constant wet/winter/road salt conditions and therefore needing attention. My cable disc brakes are mostly fit and forget!

[@TheSpaceBrosShow]

Hope is also dot. Trp, Shimano and a bunch of others are mineral oil

[@nelsonglover3963]

I really don't understand point 1, how is water getting into your brake fluid? The only way I am aware is if it condenses out of the tiny bit of air in the resevoir.

[@FurySpyder]

@@nelsonglover3963 just that. It happens gradually over time, either via the reservoir vent or anywhere else, e.g. around the callipers etc wherever tiny amounts of moisture can get in. Eventually the volume increases and the system is over filled with fluid and you have to flush it through and start again.

[@hypez604]

I've been running the mechanical juin disc brakes on my DH 29" mtb which is built around a airwolf carbon frame that can be had on aliexpress. Can't complain at all. Low maintenance and more than enough stopping power for my 72kg bodyweight on steep downhills. Nice videos mate!

[@filippofiamma3640]

I've had the HY/RDs on my road bike for about two years now and I've noticed a clear improvement in both power and modulation compared to the already good mechanical TRP Spyres I had before. I confirm that compressionless cables are necessary (I also have Jagwires) and that the original pads are not exceptional. The only flaw they have is that, for what they cost, spending a little more you can buy a set of full-hydraulic controls and brakes: I bought them because I found them on sale.

[@MuttCG]

I upgraded to a TRP hybrid and really like it. The only thing I didn't like is the lever travel, so I bought a slightly thicker disc brake from Magura Storm HC and that really helped to make them closer to fully hydro.

[@gruensein]

Before upgrading to the SRAM Force hydraulic brakes, I used to have a set of these coupled with the first gen SRAM Red Etap 11 Speed for mechanical brakes. I spent more than one cycling vacation in the Italian alps and they handled it quite well. That being said, the fully hydraulic brakes are in another league if you ask me. Also, the required lever travel was pretty big so I had to use compressionless housing, get the setup just right and even overcharged the calipers a bit to prevent the levers from hitting the bar. All in all, these things are a good option if you have a group set for mechanical brakes already and with a little tweaking, they work well. Otherwise, my recommendation is to spring for a group set with hydraulic brakes even if that means to buy a lower tier group.

[@philipcaldwell3187]

These things are well engineered, precision manufactured and my # 1 pick for reliability and ease of maintenance, no other competitors out there. Well done TRD!

[@christopherharmon9336]

I have Tekro Aries mechanical discs on my 2019 Radwagon (Bike weight: 73 lbs / 33 kg). The brakes were not much more than adequate. As an experiment, I threw compressionless housing on the bike. WOW! What a difference! I can now easily lock up the rear wheel. When we discuss mechanical vs hydro brakes, the discussion needs to focus on QUALITY mechanical brakes, meaning brakes which were actually designed to stop a bike, and the entire system. Avid BB7s, TRP Spyres, compressionless housing and rotor diameter. Let's also factor in use. With high-quality mechanical brakes and a larger rotor (if possible), I'm not sure the gap in performance between hydraulic and mechanical would be significant for most people. If you're racing, or say you are a very aggressive mountain biker, four piston hydraulics is probably the way to go. I use my old hardtail for light XC and what are effectively gravel rides. The Avid BB7s with 203mm/160mm rotors are more than strong enough to stop the bike.

In my opinion the discs make one of the biggest differences in stopping power along with the pads. I have been running TRP Spyre SLC mechanical brakes and Clark’s solid metal discs, with Noah and Theo pads. Stopping power is amazing and much easier to adjust the callipers than any other type of brake.

[@johntheman2006]

Great video. The one I was looking for in detail and clarity. I’ve already ordered a set of HY/RDs and can’t wait to fit them.

[@DavidRichards-qj3fg]

I've been using the HY/RD for 3 years on a summer road bike, a winter road bike and my gravel bike. They are brilliant. Just like calliper brakes they need adjustment to take account of cable stretch which is a 5 min job with an allen key and pliers. Oh and 3 years in and haven't even needed to replace the brake pads on bikes that have each done c5,000 miles over that time.

[@casperbachjunckerkennild2592]

I love my TRP's, that came with the bike four years ago... They work just perfect for my needs!

[@zethjugos1250]

Still using trp spyres. Fully mechanical 2 piston calipers. A good set of cables and housing and they feel nice. i like them bcoz they provide excellent feedback and are very strong. Honestly dont feel the need to go hydro...

[@williwacker2774]

And no need to do that bloody bleeding or dispose of caustic DOT fluid.

[@Platypus_Warrior]

Just to play devil's advocate here, as an outdated bike mechanic I think rim brakes are underestimated. Disc brakes are heavier, better for wet conditions than rim brakes but still if you know how to adjust them, they are great and cheap. The video really lacks considering weather conditions, Cable brakes can vibrate in wet much more likely than full hydraulic I think. With rim brakes in wet conditions, I like to graze the pads to the wheel regularly while riding to warm the pads and dry the rim so that when I brake it bites well from the beginning. People spend so much at times while knowledge and maintenance is about 75% of what a bike needs with its exposed mechanic to work well. I could keep on (expensive aluminum packed gels vs banana, 2x11 groupset vs 3x9, ...) Historically road cycling didn't do much for tech compared to MTBs where disc brakes really makes sense and for a commute bike, you are much more likely to get it stolen with shiny discs than regular old fashion light rim brakes ;)

[@robbijay]

Firstly, I get genuinely excited when another of your videos drops. It’s always the next one I have to watch! Secondly, I’ve got Hy/Rds on my endurance/year round road bike (replaced the awful proprietary Giant version ) and they’re barely any worse than my Ultegra 8100 on my ‘good’ bike. One of the best upgrades I’ve got rather replacing perfectly function mechanical levers. To be fair though (and split hairs). They’re not mechanical brakes, they’re cable actuated hydraulic brakes. So long as you use compression less housing it’s no surprise how good they are.

[@johnmaheu4037]

Luke, great video. From my experience Growtac Equal are the best mech disc brake on the market. Light, good looking and essentially hydro power. But they are expensive and you likely can get the 105 11-speed hydro for their price.

[@blze0018]

I was really debating what to do to upgrade my old BB7s on my touring/commuting bike, converting it to full-hydro with the rear IGH was going to be eyewatering. Thanks for the tests and breakdown, definitely upgrading to these over the winter.

[@petert8931]

Great video and testing, nothing that surprised me. For me, TRP HyRd lasted ~ a year before becoming terrible, I had it shop bleed and it worked for another 3 months then the problem re-started plus the 2nd brake also started going. I tried TRP Spryes for a couple of rides and quickly moved to Juin F1 when they arrived ; absolutely top Tier , they have been perfectly fine for the last 3 years. I don't find any tangible disadvantage over my other full hydraulic setups. If I wasn't being forced into wireless/full hydraulic groupsets etc - my bike build would definitely include cable -actuated brakes. (+ Juins comes in pretty colours)

[@MerlinMan1579]

I used the TRPs' for many years, but after getting frustrated with the bleeding process I got a set of Sram Bb7 cable actuated calipers and they are superb, heaps of power, good modulation and very easy to tune as the pads wear. Be good to see you review these.

[@MrKin92]

I had these juin techs, trp hyrd as well as most of the common branded chinese half hydraulic caliper. TRP was the closest to the actual hydraulic brake. Just a note to those who wants to use these calipers, make sure your shifter has sufficient cable pull. TRP HYRD is designed with Shimano SLR EV cable pull. Else you will not be able to brake even when your lever touches the handlebar!

[@Ob1sdarkside]

I have mechanical on my commuter, changed the pads, and the stopping was superb

[@CharlieMetcalf]

Thank you for the recent videos of you testing. I asked and you delivered. thank you

[@StickmanAirsoftPH]

The problem with these hy/rd in hotter climates is that reservoir is close to the calipers therefore heating up the fluid and making it less effective in braking.

[@paullevy-adophy9198]

THE ULTIMATE TEST I have watched I think all of your brake testing but I think now is the time to do the ULTIMATE TEST which I suggest would be this: 1) Standard mechanical disk brake caliper (the types where only one piston actually moves) with standard brake cable housing. - vs - 2) TRP Spyre Mechanical Disk Caliper (these have TWO moving pistons) in conjunction with Jagwire Pro Compressionless Brake Housing & Pro Slick Cable -vs - 3) Juin Tech hybrid brake caliper (hydraulic caliper that is cable actuated) and again using the Jagwire cabling -vs- 4) TRP HY/RD (the caliper you highlight in the video above) along with the Jagwire Kit -vs- 5) Full standard (i.e. two piston) hydraulic brake system. I think such a test in one comparative video would give a clear picture of exactly where these different braking systems stand against each other. My personal take on it is that, the reason mechanical disc brakes have such a bad rep is down to urban myth based on 99.9% of people who have used mechanical disc brakes have used that pile of junk that I describe at option 1 above. It should be pretty obvious why those things are bad (relying on just one piston & pad which has to physically move the disc rotor over to the other pad). Once you get to option 2 (TRP Spyre calipers (TRP Spyke for mountain bikes)) then braking improves exponentially. Also, nearly all mechanical brake setups use standard "squishy" cable housing rather than Jagwire or Yokozuna Compressionless housing; Compressionless brake housing makes a huge difference. Hopefully, you'll take up my suggestion. It will be VERY interesting to see.

Mounted a new 180mm rotor and then the 15 year old mechanical caliper with the still original pads. And they work marvellous. Modulation and even stoppies aren't a problem. So for me they get an 9 for price value 😅

[@williamdanielhunt5567]

I still use cable discs on my gravel bike, I admit that they are not quite as powerful as my hydro road bike brakes but and this is the kicker it's NOT far off. The key, I think, is to use the correct setup so basically junk the pre-installed brake housing and use compressionless brake housing (SL pro etc) and I also find decent aftermarket pads really make the difference. With those 2 changes my brakes are 90% of my hydros and cost about 30% cost. I should add I am 6ft and 96kg and with proper setup and 160mm rotors my cable diac brakes are still powerful enough to send me over the bars if I so wish!

[@unionholdingsnightingale8248]

Just note that the added reservoir makes the overall caliper taller and will not clear some frames, especially those with lower sloping seat stays. Otherwise, they are great! You can adjust pad clearance with the built in cable tensioner just like regular rim brakes!

Hi mate! Pleasent material overall! Not to challenge the performance of these breaks I need to say that a proper breaking test should include both bikes on the same tyre (model, wear and pressure). Actually it should not be so complex to swap and use one wheelset if u had them set up for the same rotor sizes :) unless the tyres were same and u just didnt cover 😅

[@andrewwhite1065]

As good as they are, they look bulky which usually means heavy. Will try a pair on my e-scooter if there's room and possibly a larger quality rotor as well. Great review, as i was recently told by a shop owner that there were no decent combo units available.

Always a pleasure to hear about your "Massive skid marks" young Trace me lad.

😂🤮😂

Just bought these, need to install them still. Looks like I made the right choice. Very specific in my case. I ride a trike and only have my left hand. I have been using a doyble lever for a long time. So the one lever for 2 cables for front and rear brake. I found a few fully hydraulic options for 1 lever, but really expensive. Plus I prefer if one brake fails I still have the other one. When a fully hydraulic double lever fails because of a leak or so, all baking power is gone.

Hi Luke, this is the episode I've been waiting for. Thanks. So the master cyclinder works on the same principle as a car one. It would be a better weight comparison to compare calliper/mech lever/cable to hyd caliper/ hyd lever/ hose. Some of the weight might have been transfered to the lever. I think you are right, its a toad, it has the pimples on its back. You might be doing the wrong thing by your frogs by putting back where they came from. They are on their way to the breeding pond so better to help them over. IE put them on the verge they're pointing at. Well done though for looking after them. Best wishes and a basket of bagettes (I don't know how mojis work).

excellent video. very informative. infectious enthusiasm. more success to this channel. tnx...

[@williamko4751]

I don't ride in the 🌧️. I stick with rim. Thank you

[@rohangayle9130]

Thanks for that Luke, been riding off road since the eighties,a cable has always served me well,no doubt the disc and hydraulic have moved things forward,but the bike is and for me a simple efficient machine,and a cable suits me with hydraulic power is all good for me, anyway I ride by feel and old skool skills,not MODULATION

[@themoss7115]

Biggest advantage of hydraulic brakes is not the braking power itself, but rather what it allows you to do at the other end. More raw stopping power and no cable slack gives you freedom to design perfect brake levers for the situation. Everything between brake pads and lever is basically a gearbox, and hydraulics has almost no loss in comparison to cable. You can trade between finger effort and lever throw very easily. But for average joe on a road bike, RELIEABLE mechanical disk brakes are good enough and definitely better than bad hydraulic brakes for the same cost.

[@jaredsurato4213]

I use mechanical disc on my Soma Fog Cutter and don't have any issues stopping. I notice a little more "squishiness" compared to my hydraulic brakes on my mountain bike but it's not a huge difference.

[@EstebanRapido]

I have several mountain bikes, but my rigid frame single speed steel mountain bike gets the most use. It has cable disc brakes. I wouldn't even consider changing to hydraulics for that bike. The brakes work great. They are high effort but they are so easy to adjust and maintain. At the same time, they give me more feel.

[@AG-el6vt]

The thing is, once you lock up the wheels, it's up to the rubber/ground friction to stop you. If you have crappy brakes, like you said in the intro, you won't even get to skid. Hard braking is two steps: initially slow down with brakes, and if your brakes are good enough, they decelerate you enough, and then tyre friction takes over. So I think the tyre limits to how quickly you can slow to a stop. And the interesting bit for me is: if your brakes are good enough, there is not much real-world difference between good (powerful enough) brakes. Of any flavour. And that includes good rim brakes.

Great video and as always, love the bonus clip time 🥖🥖🥖🥖🥖🥖🥖

I used the TRP HY/RD brakes on a road/gravel build a few years back. They worked without problems and still are actually. Not quite as strong as full hydraulic brakes but otherwise quite good.

[@IceGene]

I don't know if you'd tried them already, but a Tektro C550 is pretty great for a fully mechanical disc brake caliper. Basically a slightly cheaper TRP Sphyre. Clamps on pretty much like a dual piston caliper (which it actually is). I almost OTB'ed when I pulled the front brake pulling into parking at a cafe one time. I trusted them on long descents too.

[@KNURKonesur]

My GF got HYRD for her gravel bike a couple months ago, we haven't installed them yet cause we're waiting for spring season and more cycling into the wilderness. That 6 piston JuinTech one will be an interesting watch cause I'm just debating buying JuinTech brakes, but was wondering between the classic 2 piston ones and the GT 4 piston ones. I'm quite heavy and although mechanical disc brakes have worked decently well for the longest time, I'm keen to see what could happen with much better stopping power.

[@kennethg9277]

What could happen? What will happen is that one day you'll freak out at something, press the front brake at speed and fly over your handlebars Cyclists just don't need stopping power. They need anticipation and awareness

[@Amir-cu4qp]

Great video! You should also try the growtac equals, really expensive but apparently also really good

[@mrx1979ua]

I use TRP pure mech disk and have never had a single issue. Thousands of kms, dozens of

[@lpoolck17]

I think the rear rotor size will have a bigger impact than what you think. Granted, the front disc does the majority of the breaking. But the difference of 160 to 140 will be noticeable. Great test and very informative as always 👍

[@LawrenceSeetoh]

Thank you for the review, the Hy/RD has always been one of the better ones out there but I am excited to see you try out the Juintech ones, the reviews for their stuff shows promise as well. I would argue that a cable actuated hydro is a good step up from a cable pulled disc brake. No everyone ( me) wants to deal with switching over to a fully hydro set up. I am happy with the Tiagra groupset I have on my bike, but would still love better braking performance and I've already switched to semo-metallic pads and compresionless housings, a cable actuated hydro brake is the last step for me. 🥖🥖🥖🥖🥖🥖🥖🥖🥖🥖🥖

Older microShift and Shimano shifters with exposed cables have higher mechanical advantage (about 20%) than other shifters with concealed cables. You will have weaker braking force and shorter lever throw when using different shifters. At 4:35 the long lever stroke shows clearly these are not suitable for that kind of shifters. I remember TRP states these brakes are optimized for Shimano shifters with concealed cables (i.e. starting with 7900/6700/5700). AFAIK, Avid BB7 road is the best choice for shifters with exposed cables (and pre-2009 Campagnolo shifters, which also have high mechanical advantage). You may do another test with other shifters to get a more balanced assessment.

[@JetsetJive7]

Great video ! how did you manage to bring 2 bikes to do the test ! amazing effort !
