Do You Need To Service Coil Suspension? |

[@sionjones1675]

Big respect for admitting you didn't know the answer to the kashima colour variation - much better than some youtube vids where waffling on and making wild assumptions are the norm. Integrity, you has it!

[@iffy_too4289]

If you need to ask if 29 inch wheels are better than 27.5 ones then you wont notice the difference. I just dropped from a 29 HT to a 27.5 full sus and I have no idea whats what. The only difference i noticed is I now ride faster up hill and small bumpy things which is contrary to popular thinking on the subject of wheel sizes, but that prob due to the suspension making it easier. Aside from that, its great. Im not a racer, im just someone having fun and its awesome fun with my 27.5. Forget wheel size, buy what you think is good value.

[@RustyMTB]

Rider skill and style is more important than bikes. That said 29ers are pretty cool, they have this feeling of speed and momentum that’s unmatched on 27.5. I am a fan of 27.5 because they have the ability to change direction so easily and I love it for bump jumping, quick cornering, and goofing around

[@kiltymacbagpipe]

The difference between 27.5 and 29” isn’t really that massive. Compare a 26” to a 29er and I think the arguments become more valid. Bikes are systems and looking at one part in isolation is kind of silly but that’s what the internet is for.

[@stevepadilla9729]

I use to race years ago on only 26” wheels. We tried wider tire and it made the tires taller and that made the bumps feel softer, but seemed to have more tire flex in Tight turns. I went to a 29” now in my old age. I found the wheel flexing more in tight turns and even will rub on my frame. The 27.5 seem to be the better of the three in the back. Fast in turns and less flex like the 26”. I use a 27.5 rear and a 29 front on my Foes now and I like it. But over all at being 59 years old, loosing weight on my body will help me last longer on the trails and may help with less flex in the wheels.

[@tristanmcfee5238]

What I found from switching 27.5 to 29er is that I had to start cornering a little earlier but that is the only difference I found other then the bb height

[@jamlarna]

My gf has a 29er and I ride a 27.5, iv ridden both and if I'm honest I really can't tell the difference other than the fact I feel more in the bike than on the bike with the 29er, I definitely prefer the look of 27.5 but I suppose it's what ever you like. Try both and see what works for you 🤔👍

[@klutvott1232]

There's no kashima coating on the DHX2. It's Titanium nitride and that's why there's a color difference

[@hobmarg]

and for 2021+ they abandoned the coating due to putting on the shock shaft.

I have set up my bikes tubeless with stans Schraeder valves. They work great. Zero problems

[@SnootchieBootchies27]

For the brake vibration question. If your rotors are worn out, this can cause a gnarly vibration. Sometimes the center part of the braking surface (where the vent holes are) will wear thinner than the outer and inner, more continuous zones. A good sign that this is an issue is your pads will be worn convex.

[@uproblylikedingus]

Thanks bro

[@roythearcher]

The differences in the colour of kashima coatings are , as you say, down to the particular aluminium alloy used as well as the process itself. Slight variations in the time taken as well as temperature of the process will mean there are slight variations in the final colour which don't affect the performance of the coating. You find the same variations in anodising too due to the same differences.

[@notyourbro5519]

It is still pretty interesting that even the same year, the same spec forks (me and my friend both have the 2021 fox 38 grip2) have differently coloured coat, and it's a big shade difference i'd say. Not worried about performance at all, it just stays a mystery for me.

[@Tom-ew6jn]

​@@notyourbro5519 hi the colour comes from dye in the anodising process. we like gold coloured things . watch AvE video. BOLTR: Bike "Technology" it's a bit long but he explains it as he tears down a rear shock

[@rodrigopages1054]

@@notyourbro5519 the shade difference comes down to day of production of your stanchions. Aswell as the concentration of the dye used in the anodising bath (along with other parameters) during production time. If they both were from the same rack that went into the anodising bath they will both practically exactly the same colour. But since they are different colour it’s basically obvious they weren’t produced the same day

[@ianiscaratti4924]

I had a 29" ht modern long and slack bike and changed it to 27,5 and it was a huge difference to me. It felt like going slower but more on the limit to a crash. Comparable to pumping up tires to 4bar instead of 2. The front wheel did get stuck often what forced the fork and my arms to work hard. Changed to mullet. It was half bad. The bike was designed for 27,5 and 29" btw. The lower bb on 27,5 or the slackness on the mullet was something i did not feel at all but the stronger brakes on 27,5 were impressive. I'm not even a tall, a good or neither a very setup picky rider but the difference to me was huge.

[@MitchzPlayground]

Same goes for coil forks. I pull all my suspension apart during Christmas holidays each year and check things over. If they need a full service, I'll order the parts and do it. If not, I'll top up the oils and clean everything and keep sending it. My coil Boxxers are way simpler and hold up better than my dual air Pikes by a mile.

Great info as usual.

[@f4yur827]

5:12 to that person, another reason for brake shutter (which has happened to me) is when you turn the handle bars to 90 degrees or so to put them on a crowded roof rack etc., the fork may get loosened from its frame etc. creating brake shutter. What I did to fix it was opened up those two side bolts to turn my bars (but leave them as is) and then with that, you’ll be able to tighten that middle bolt on the stem cap/top cap. Then close those side bolts up and it should be fixed (assuming that is what the issue was)

The difference from shades of anodising comes down to concentration of the pigment used in the anodising bath/process. This will be also affectb different production dates and production lots. For this parts fox probably has a standard of shade/tone that parts will be acceptable for production use. Like you also mentioned the type of material or preparation of said material that requires anodising will also affect the colour of the final coating not by much but sometimes enough to be detected by sight of a consumer ! :) hope it helps I’ve worked for 2 years on an electroplating shop doing several different metal coatings including anodising (which is what kashima is)

[@ThunderStruckMTB]

Rotors with a lot of cutouts (like Ashima) will cause brake pulsating. I use SRAM Centerline rotors with my Shimano 520s and they are the smoothest feeling rotor I have used.

I used to run a shrader tubeless system as my bikes rims where Schrader and still wanted to run tubeless.

I went tubeless schrader using the Joes scharder valves. I drilled out my cheapish rims and its been fine so far. Pros: less of a faff to fill up, and valve cores are cheap and readily available.

[@mikes4163]

I actually decant into a 15ml needle applicator (£3.50 for two on ebay) for my normal dry lubing because the manufacturer's bottle has a ridiculously oversize hole meaning I use two or three times as much as actually needed - and it's not cheap stuff. For a long day I could easily take that tiny bottle with me.

[@syntrax-og]

I really don't know why nobody has made a video on servicing coil shocks.

[@spencercheekymonkey]

The simple answer : because it’s a fuck on, 100 specific tools are needed, you need nitrogen….. quite a lot of reasons.

[@jeffv.akaonsjeffke9865]

Because you only need to keep the shaft clean. When they start leaking oil it's time for a new seal head unit, which you can' t do at home as you don" t have the nitrogen, or the pump to get it filed up correctly with oil without air in it. When it leaks or feels to soft, ship it out to a suspension guru.

[@adammccarthy2157]

Fox recommends that the minimum suspension fork and shock service is 125 hours of use, yearly, or whichever comes first. That is certainly on the longer side of things. Similar to changing the oil in your car, the more frequently you service your suspension, the better the fork will perform for longer.

[@edrcozonoking]

The Kashima coating difference is probably own to process. Different locations, slightly different temps/current etc....

Random question Doddy, at what point does sprung mass become irrelevant for a mountain bike? Obviously lighter wheel set ups and cassettes are a must, but how much of a difference does the weight of the sprung mass matter if a majority of the mass is the rider themself? Thinking of how much a difference it makes on a downhill aluminum frame vs downhill carbon frame. Commencal vs the rest essentially.

Brake shudder can be caused by disc contamination, i.e. if you put a bike away with wet discs, it can cause slight rusting where the pads sit, then the difference in friction causes shudder as it passes over that part of the disc when braking. his caused me issues on one of my sports bikes in the past

[@polishguywithhardtospellna8227]

Imo brakes shudder in MTB is natural and comes mainly from wide spread tread blocks on your tires. Other minor causes might be large holes in disc rotors. Both cause pulsation in braking force transferred from the system to the ground. I fully stopped worrying about it. Also if you notice it less on soft woodland soil and more on tarmac, that's a no brainer to me. If you have a friend with a road bike, I bet he'll tell you he never felt pulsation from his disc brakes, due to slicks.

Hi there. I was riding mtb eight years ago and now it's time for the inevitable and to going back to trails. From my experience, most of the time I enjoy riding xc trails but I really do enjoy, from time to time, to ride on technical singles. Nothing to crazy though and with no intention to catch much air any time soon. People say that todays xc bike and hardtails, with their modern geometry, can do very well on an occasional pretty technical terrain. So they claim that I should prefer the paddling efficiency of xc bike and not giving up at all on enjoying my local singles. Would love to hear your opinion. Also, if it's important, I am not going to spend too much money right on the beginning, probably around 1000$. So i was thinking maybe I'll by Polygon Xtrada 6, or something with a similar geometry.

[@danp2509]

If you are able to, visit a lcoal bike shop and try both a medium and large. You may find that you can't get the seat as low as you would like for descending on a large due to many mountain bikes not having straight seat tubes, or if it includes a dropper post, it may be too long. Swapping stems to increase reach does work, however, I wouldn't increase stem length by more than 10mm personally as a long stem and wide bars makes for slower and less responsive steering, but if you increase stem length and shorten the bars, the handling won't feel as stable at higher speeds. This does depend on what type of bike you are getting. Most trail/enduro bikes have short stems and wide bars, and you probably wouldn't want to increase stem length too much, but if you are looking to get an XC bike, you can play around with stem length alot more as theses are made for climbing and slower speed descending.

If it's a hardtail, they make dropout realignment tools where you can adjust the spacing. However, 13mm might cause metal fatigue over time. It'll certainly not be good for the wheel. If it's a full sus or carbon frame, then this is just straight up a terrible idea.

#askGMBNTech Hi Doddy! although you said wheels larger than 29" would be stupid and not needed, can you see them being manufactured in the future? Even though they would be pointless in your opinion, do you think it could happen?

[@hankclifford9782]

#askgmbmtech i recently bought a derailleur hanger for my norco fluid fs 3. its worth noting the thru axle screws in to the hanger not the frame and when i installed the new hanger, it fit into the frame fine. but when i went to put the thru axle in it didn't screw into the hanger because the threads were different! the thread on the thru axle are a lot finer. i didn't know about this could you educate me on different thread types?

While we’re on the subject, What is the best way to unclog a shrader valve?

[@brookerbilly8938]

Remove the valve core and replace it from an old tube if you have one other wise just pick at it same for presta

[@michaeltrollope8048]

Presta system clogs up but easy to clean, if your shrader clogs would be hard to clean... probably need a new valve

Hi. What is your take on a chain lube that is for both dry and wet conditions? my last chai lasted for 1,300 miles, which doesn't seem bad.

[@danp2509]

unless you're doing all day epics, use dry lube all year round

#ASKgmbntech How permanent is a plug as a fix for a slow leaking puncture ?

[@keanubartolata3465]

#askgmbntech love the show. Its been flooding lately. what do you think could possibly happen to my bike riding 0.5m to 1.0m of flood water? How would new bikes do compared to old bikes? Shoutout from the Philippines

#askgmbntech Is there any way to see any telemetry from braking in trail, braking points, how hard you pull the brake ex. It would be awesome to see how pro riders use their brakes while riding. It would also be very cool to see like a POV riding videos whit braking usage in the low corner of the video something like they have in formula 1 where u can see how much they use brakes or gas when they drive. Would be very nice thing to see and learn from.

Here’s a thought… ever since I bought a gearbox bike with a belt drive, almost all the tech advice and recommended maintenance issues just went away. Derailleurs, chains and chainwear, cassettes, hyperglide vs XD, chainrings, clutches, jockey wheels, etc. Just not a problem anymore😊

#askGMBNTech. Hi Doddy. I am looking to get a new set of wheels for my bike. The wheels I'm looking at have 30mm and 35mm internal rim widths. The 30mm can fit 2.4-2.8 inch tyres and the 35 can fit 2.5-3.0 inch tyres. My bike has 29x2.6inch tyres. Would it be better to use the same size rims or use the 35mm on the front and the 30mm on the rear?

[@guilbertjudegarrido9470]

#askgmbntech Hey Doddy so I have cut my steerer tube too short for my new stem. Is using a "Stem Adapter" / "Quill Adapter" of 25.4mm is it safe for trails?

#askgmbntech i bought a brand new bike the vitus nucleus 27 vrs 2021 and I got a deep long scratch on the main frame from leaning the bike against a rock how can I fix it?

[@tristanmcfee5238]

#AskGMBNTech I am looking at getting a bike that can tackle everything from the bike park to shared trail use centres and have narrowed it down to a couple of bikes, the Giant Reign 29 2, the Canyon Spectral 6 or 5 and the Canyon Torque 5. Which would be the most capable to handle Big White Bike Park, shuttle centres and peddle up locations? Basically I am looking for an all around do everything bike that is $3000-$4000 CDN, any suggestions or tips on the three bikes?

You can do a 29ner mullet ??

Hey Daddy love the show, I've a question, can I use a 500x2.65 Coil on a 222x70mm shock. The original was a 450x2.75 but it is too soft. If yes, does it change the geo on my V10? Can't find a 500 or a 525 in 2.75 at the moment because it out of stock everywhere. best regards #askgambntech

How do I know when my cassette is worn and needs replacing?

[@jeffv.akaonsjeffke9865]

When your chain starts slipping over the sprockets under heavy load. Watch out for your knees to not hit the bar....

[@peterlang5047]

You’ll know if you need a new cassette if you install a new chain and it skips and doesn’t shift well

#ASKGMBNTECH Hi Doddy, big fan! I’m not that experienced with using different types of greases with MTBs. Was wondering whether Teflon grease can be used as a general grease for bikes. I know it isn’t good on carbon components but is it alright to use on cranks and dropper seat posts? Is it alright to use it inside both front and rear suspensions? Couldn’t find these answers anywhere. Really appreciate your help!

[@WolfPawArmoury]

#askgmbntech I've got a 29er with a rear freewheel that I want to upgrade to cassette, but I wanna keep the rim since it's like 26mm inner width. Can I just re-lace the wheel to a cassette hub with the same flange diameter?

[@mtbmates6100]

#askGMBNtech hi doddy I was wondering what is the difference to the ROCKSHOCK ZEB R and normal ROCKSHOCK ZEB

[@mortonfrankfire5400]

#askgmbntech my chain rests on the chain stay protector when the smallest sprocket in the cassette is selected. Is there a way to increase the tension on it between the cassette and the chainring? I thought about removing a link but can’t see how that would make a difference between the cassette and chainring.

[@danp2509]

have a look at the clutch on your derailieur, that could be loose or damaged, also have a look at chain wear, although I don't think chain wear woud cause a chain to rest on the chainstay. Is it still the orignal chain on the bike? If not who fitted the new chain?

[@alcosamwel]

#askGMBNTech hello doddy whats the best (permanent) way to fix a slow leaking puncture??

[@matthewedcelinocentes1620]

#askgmbntech supp dody. Did you ever tried putting linseed oil on your spokes and other screws. If yes, how do you do it and how long it will last. If no, good day to you all

[@mr.toffee8705]

#askGMBNTech can you install a dropper post on a DH bike?

[@AJ-jr3ej]

Hi Doddy, I changed my new bike to a tubeless set up 3 months back (new tyres) , it seems like the sealant (slime STR) had dried off and the rear wheel looses a lot of air. Im planning to change the sealant brand of my tubeless setup. Will changing the sealant brand cause any issues if I top up the new sealant (muc-off)? Or should I strip the tubeless tape, remove the old sealant from my tube and wheels and then apply the new sealant? Thank you. #askgnbnTech

[@danp2509]

probably wont cause an issue, I'd take the tire of and clean the tire and rim, but I wouldn't remove the rim tape unless it's damaged

[@kirawr8064]

Kind of a specific question I have a budget fork on my mtb that won't compress when i put weight on it directly from above(or in a riding position) but it does compress when I push the front wheel againt a wall. Any idea what the problem could be and how i might fix it? Btw it was working just fine for more than a year now

[@peterlang5047]

If it’s a super cheap fork it is not serviceable, so there’s nothing you can do

I bought new Continental Ruban tires both 2,3 inch but i discovered that my back tire is rubbing against the frame. Is it possible to just go for a 2,3 inch in front and a 2,1 inch at the back or will this make some problems. (And i can not send my tires back because i lost the receipt :( ) #askgmbntech
