Regarding disc brake upgrade: I have cable actuated hydraulic brake calipers (TRP Hy/Rd). They're outstanding! Much easier to maintain than full hyadraulics, works with "regular" shifters and the performance difference is negligable. I've had full hydraulics and high end mechanicals, but the cable actuated hydraulics brake calipers are my absolute favorite. Perfect compromize between ease of maintanance and performace. There are other makes and models. My experince with the TRP Hy/Rd have be falwless

Be aware that the Hy/Rd don't play well with all STI-levers/"brifters". I tried them on my SRAM Rival1 levers and they didn't pull enough cable to fully engage the brakes. You can buy a modification to the Hy/Rd piston mechanism that requires about 30% less cable travel and that would probably have solved my problem. I sold them to a guy who had Shimano controls and they worked perfectly.

@@larsgustav.gudbrandsen I have mine paired with rival 1 shifters too. Initially I thought I had the same issue. But just by pumping the brakes vigorously after dozen times, the pistons selfadjusted and the problem went away. When I was trouble shooting I learned two important lessons: a) use compressionless brake cable housing and b) do not adjust the cable tension so as to "pre-load" the brakes. Just set it up according to the instructions and keep braking and let the hydraulics do their magic self-adjustment.

Joel - I upgraded from Avid BB5 to a pair of TRP Spyres. The Spyres are fantastic mechanical disc brakes and a simple transition on a mechanical-setup bike - no need for new shifters etc. Spyres also have modulation on both sides of the pad meaning you can dial each pad in or out independently.

Agreed. The Spyres are far superior to the BB5 and most other "single-sided" mechanical calipers. They are also super easy to maintain and set up. I use Spyre with my Rival1-kitted Kona Sutra, with SwissStop organic (green) pads and TRP 2-piece, slotted rotors. The stopping power is more than adequate.

Disc brakes are fantastic in wet and horrible winter conditions but Shimano 105 and above rim brakes are great as well and perfect for fine weather riding.

Regarding endurance riding, I chose the Orbea OMX. (It’s ready to go, but can it get here through the pandemic?) Like many of the latest drop stay bikes, it has discs, has some aero features, is stiff, is lighter and more comfortable than an aero bike, can take 32mm tires, and has a moderate geometry. A true all-arounder. There are a few bikes in this category that could work without going for a full-on, relaxed, endurance bike. Get shallow wheels if you climb, deep wheels for aero, 25mm tires for quickness, and 32mm tires for comfort and light gravel. N+0. Can’t wait for it to arrive!

Corey Allert That would be very useful actually - I would expect the full hydro to be the most consistent over a long period of time but when all well set up I would be surprised if there was a huge difference in everyday performance. Then take into account maintenance - I decided against the part hydraulic on my touring/adventure bike so I knew I could easily fix with a cable when out. Stopping power over the original set of cheap cable disc calipers was huge without having to change shifters as well

For the individual who wants to upgrade their disk brakes. What I would suggest is the TRP Sprye-C Mechanical caliber. Works well with any Mechanical pull brake lever wether it be flat bar or drop bar or something in between. Duel pivot movement so both pads are coming into contact at the same time and have a great feel and modulation. Oh and they are way lighter than the TRP hy/rd, cheaper too.

For over ten years I rode a stiff-as-hell Pinarello Paris aluminium race bike for training and recreational riding and never had an issue with it. When I hit 60 it began to feel a little less comfortable, probably as my body was aging and becoming less flexible. I bought a Lynskey gravel bike last year (and so even more relaxed than an endurance bike) and stuck some race wheels and tyres on it. It was a revelation in terms of comfort and was really only a smidgen slower. In other words, age matters - what you can ride happily at 30 may leave you limping at 60, at least in my experience.

One note on zwifting saddles: you don’t care how heavy it is on the trainer. I swapped a Selle Anatomica from my gravel bike to my road bike mounted on the saddle, adding 150gs. It was significantly more comfortable than any other road saddle I’ve tried while riding a trainer. Out on the road, I’ve swapped back to a lighter road saddle. So, looking for a used Selle Anatomica or Brooks leather saddle might help with your sore backside on a trainer for a reasonable cost.

Regarding chimneys, not all setups need a spacer on top. Cannondale Si setup on a CAAD12/ last model Supersix state *NO* spacer on top, with steered cut down below the top of the stem. The top cap itself supports the steerer where the top bolt of the stem is clamped, with the lower bolt being supported internally by the expander bung inside the steerer. If you put spacers above the stem it can result in the expander and top cap being in the wrong place. Instead would recommend those with OEM parts to check the manufacturers instructions, and if you use aftermarket bits to use your noggin to work out what's best.

One reason sitting on a saddle can be less comfortable indoors is sweat. Even with fans, you still get less wind on your lower parts which makes more difficult on long rides. One thing I had done is put an extra fan behind me. I also build one of those DIY rocker plates (there's a FaceBook group of rocker plate DIYers). They are great. People think they're for simulating rocking your bike when riding out of the saddle. They are more for comfort because your bike keeps moving slightly and it makes a great difference.

On the subject of upgrading mechanical disc brakes, you can by changing out for center pull or by changing to larger sized discs. The center pull calipers will pinch on both sides and be more consistent than single piston calipers, and the larger discs have more leverage resulting in greater stopping force. Just be sure to get the proper adaptor for a change in rotor size.

This is really interesting! If you look at it from a physics perspective, assuming that the tire volume doesn’t change, the pressure in the tire does stay exactly the same (as is ideal gas law PV=nRT states). As the pressure stays the same, so does the force that pushes the tire against the tarmac, hence the ride quality is the same too. In a realistic scenario the tire might even expand a little, because there is less force pushing form the outside, so the tire pressure should decrease.

There are 2 measures of pressure going on here, *absolute* pressure and *gauge* pressure. As other replies state, *absolute* pressure stays the same, or will decrease slightly as tyres are flexible and the volume will increase slightly. On the other hand, *gauge* pressure, which is what you measure when you are pumping your tyres, is the difference between absolute and atmospheric pressure and this will increase as atmospheric pressure decreases with altitude. Because it's the absolute pressure which gives the support to the tyre, the ride quality will not change with change of altitude.

FWIW, endurance bikes might not just be about a more comfortable fit, but also the "relaxed geometry" such that an endurance bike is not quite as twitchy or quick to turn in (for crits, etc.).

Absolute atmospheric pressure at sea level is 14.7 psi, and at 10,000 ft it is 10.1psi. So if your tire pressure is 85 psi at sea level, it will increase to 89.6 psi as you climb to 10,00 ft.

Maybe 1 for the nerd section.

Why do some articles I read say not to use a bike rack for carbon frames? It's my only option to transport my new carbon bike. Are there ways to lessen the "damage" they say is being done.

the ultimate endurance bike - and this also answer the saddle question - is a recumbent. You'll ride longer and farther without sores and aches. Ask Maria Parker and other Cruzbike riders how they won ultra distance races with hours ahead of the competition.

Hi GCN! I presently I have compact crank set. I am thinking change it to a semi-compact one. Do I have to change the whole crank set,or just the chainrings? What adjustments do I have to do in the front derailleur? Thank you in advance and keep safe. Luís

Hi #AskGCNTech, the show that gives me a reason to know the days of the week during the lockdown in France. I bought last year an old Lapierre Tech 7 for its components. Since I am stuck at home, I took the frame out of the attic to see how I could build a sweet commuter bike with it (I had tried the bike and it handled very well), and when removing the derailleur hanger, noticed that the frame was cracked at the junction between the seatstay, the chainstay and the dropout, just behind the hanger. The crack goes through the thread you screw the hanger with. I guess that everyone will jump in to say I should not ride such a bike. So I have two questions: - since it the "thread" still holding seat- and chainstay might give out on any big pothole, in that case am I more likely to need a taxi or an ambulance? - having the frame repaired by a framebuilder will obviously be too expensive given what I paid for this bike, but will it hold if I have it repaired (dare I say bodged?) by a local welder? Cosmetics and extra grams don't matter. Thanks again for running the show which brings us bicycle general knowledge every week!

Can I run a 1x 44t with a 11-46 cassette with a Shimano GRX rear derailleur? Would I need a wild tooth comp road link? Would it be easier to use a Shimano MTB rear derailleur? Ideally for gravel Thank you

I'm not a small guy by cycling standards - 185cm, 88 kg and happy to maintain that weight. I'm in the market for an upgrade to my 7-year-old Cannondale Synapse in the near future. Am I correct in assuming a lightweight bike would be pointless for me and I should prioritize aerodynamics? #AskGCNTech

I have a question. Maybe other's can answer or not. I took delivery of a new 2020 Trek Domane SL5 disk with full Shimano 105 group set. I haven't had a chance to get out doors with it yet but have had it on the trainer a couple times. He is my question: Has anyone else with a Trek or other Shimano 105 equipped bike had lots of chain noise when riding in the last two small gears (cogs) when in the small chain ring and in the last gear (cog) in the large chain ring? I've up graded to a Ultegra Cassette and it hasn't seemed to help.

That geometry comparison would really be worth another video, where you superimpose them for a direct comparison. Even if it became a branded thing (canyon), the difference between the models is still interesting to understand and pull apart. It’s not easy to do with single static images.

#askgcntech. I am running a Shimano R8000 groupset now with a 50/34 chainset with an 11/30 cassette, but in my daily riding, there is very little chance that I will use the 11 even the 12T. I was wondering is there any way I can change the 50T chainring to a 46 or 48T one while keeping the small 34T ring, that way I can further compress the range of gear ratio while setting the chain more straight when I ride. Thanks!

#AskGCNTech, Hi love your show - thanks for all the good advise! I got Ultegra Di2 and my FD6870 broke. The little "arm" which moves the derailleur up and down snapped (the motor is still intact and works). This "arm" seems its made of aluminum. (after 5 years / 3-4000km per year). I didnt have any crash - it just snapped. Now i am thinking of upgrading that FD to Durace. I learnt it is possible to mix Ultegra and Durace - i would do it if i knew whether this part is made of a more durable (better) material - can you help to get this info - THANK YOU

Great episode! I'm looking to upgrade my shimano WH-RS100 wheels that came with the bike, but on a budget. Would be great to have some that can withstand the cobbles here in Flandres. I've found the Vision Comp 35 SL wheels but are they much different in quality and performance? Don't know much about the brand. Cheers and stay healthy!

Now approaching 3 score years and 10 I thought it was time to make things a little easier for myself and get an electric bike (I know, I know), namely a Specialized Creo. The only problem I can see is that they use boost axles, the rear is not a problem but the front is an unusual size of 100 x 12. Can you suggest any wheels that have this size, or a hub, as I can make up my own wheels. Or are there any adaptors to change 100 x 12 to 110 x 12 or is it possible to drop the 110 x 15 down to a 12mm thru axle. Many thanks Yorkstyke
