Also about the bike going to the right - sometimes you think you are sitting straight but you are not. So it can be a bike fitting issue. Or even scoliosis, having one leg shorter and moving the hip one side more than the other.

[@questgivercyradis8462]

Yeah I was thinking the most obvious answer to the bike veering right would be the rider more than the bike. Most of us are lop-sided in some way or another even without something like scoliosis or uneven length legs. My right leg is stronger but less stable than my left. My right arm is stronger. My left hip has better mobility. It contributes to wear-and-tear type injuries too, because my right knee is the one to get achy first. Rider should check their mobility and proportional strength with a trainer before blaming the bike.

[@litespud]

When the rear tire wears out I transfer the front to the rear and put the new tire on the front. You want (1) better braking traction, and (2) better puncture resistance on the front, so the front wheel always gets the better, newer tire

[@MATTHIAS-bm2sw]

Regarding the worn out rear tyre. I always place the new tyre on the front & the stick the old front tyre on the rear. Think about it? It's far more important to have optimal traction on the front as rear will follow. 😁

[@gcntech]

How about if you were heading out for a big event? Would you treat yourself to new tyres?

[@endcensorship874]

Generally speaking, when I buy new tires I try to buy three: because two rear tires will last as long as one front tire.

On the subject of the bike veering to one side, there is also the possibilty of the rider having a slight tendancy to be leaning to one side more than the other, as a natural physical attribute. Just a thought.🤔

[@gcntech]

Great point! That's why we love the Clinic, share ideas 🙌

[@jonathanmartinrehabandrun9004]

Yes, the most likely imbalance is the rider. Unless someone spends a lot of time working on their posture and core strength they will have more tightness in one side of their lower back muscles than the other. Which will when riding no handed lead to a slightly increased pressure on one side of the saddle leading to the bike veering. Which then requires the rider to adapt their posture somewhere else to compensate.@@gcntech

JC is back…. GCN should get an App where people can chat bike stuff… sounds like a job for JC 👍

[@SnaxNoCo]

The issue with using drip wax on something like the Tour Divide is that many riders won't have enough downtime for the wax to dry since they sometimes only sleep a few hours at a time. I think it's probably better to wipe the chain and use a wet lube like Silca Synergistic, knowing that your drivetrain will be shot be the end anyway. And this is coming from a guy who LOVE wax--but who also has experience with ultra-endurance racing.

[@danhouston7596]

A celebrity cameo! Great to see Jon again.

[@zdm5290]

11:00 In countries that drive on the right side, the crown of the road will also be to the right, causing the front wheel to steer downhill. Also if it can simply be corrected by a slight shift in weight, it's possibly just their weight being skewed to the right. As a mechanic, I've ridden bikes with poorly dished wheels and the like that ride perfectly straight without hands. It's probably not the bike.

[@mikefule330]

In the UK, where we ride on the left, the bike crabbing slightly to the right may simply be the effect of road camber. Counterintuitively, a bike will tend to want to turn up the camber.

[@gcntech]

A few people have mentioned road camber! Food for thought 👀

[@mikefule330]

@@gcntech I'm a road unicyclist as well as a bicyclist and motorcyclist. A unicycle always turns up the slope of the camber. It's to do with the contact patch and the slight difference in the radius of the wheel across its width. For simplicity, imagine a cone rolling across a slope. If the narrow end of the cone is up the slop, the cone will turn up the slope.

My method for tire wear is let the rear wear out, move the slightly worn front to the rear, and put the new tire on the front.

[@SebastianTominec]

Best chain against rust is any KMC chain with EPT(electro plating) process applied to the chain.

[@VictorElGreco]

I recently rode the Erie Canalway, all the way up to Buffalo, NY. The trail, being obviously next to water and all that ambient moisture, is perpetually muddy. The crucial bit IMHO is *cleaning* the chain after every ride, getting all the mud out. The lube you put on afterwards can be whatever you happen to have at hand.

[@stephenturkLA]

If the races of your cup and cone bearings are excessively pitted, what you need is a new hub not a new wheel! There are still plenty of rim brake hubs available.

[@yonglingng5640]

Some cup-&-cone hubs have replaceable cups, like Campagnolo and Fulcrum.

[@Auszeit]

I usually hot wax my quick link, and wipe off most of the wax to refit it. It's not just the wax but the additives which provide the lubrication, and those won't necessarily be able to be wiped off while refitting, even though the wax might.

[@Local.hero.1983]

Jon Cannings is the best thing to come out of the Superbike fiasco, Manon has been in hiding regards studio since , so we get Jon back if Alex is away.

[@haraldfries7463]

@mlboulerice116 : If you have the same type in the front and the rear I would replace the rear when it's worn, but put the new tyre at the front. And the old front tyre to the rear. This way you allways have "fresh" rubber and more importently the newer tyre at the front. You need more grip and better protection at the front because a flat (or sliding) rear tyre is much more easy to control. With diffrent size tyres or tubless do as Ollie and Jon suggest.

[@bikecommuter24]

Waxing chain on a long trip, hah get a belt drive bicycle problem solved. 😆 On the the tire I tend to replace both tires if one is worn out, I do keep the front as spare if I damage one and I need to order one I use the old spare to keep riding, my Bicycle is my transportation.

[@gcntech]

Belt drive is a pretty great fit and forget system! Did you catch our recent video on commuter/touring tech 👉kzbin.info/www/bejne/mZfXoaWBj7lnias

[@mikedellar5653]

A microfibre cloth is not a magnet for dirt. As you run the chain over the cloth, you will just push dirt between the rollers; hence you will be putting new lube/wax onto dirt. This, however, is better than no lube at all; so if you’re on a long trip (300km+) do what you need to.

[@otterplay-m1k]

I put the front tire in the rear and a new one on the front

[@yonglingng5640]

That's the way.

[@simonsepic]

In response to if coated chains prevent rust I can tell you from personal experience rhat yes 100% coatings stop it. I have a child's tag along I put a red one by chain on so it's quote thick chunky layer of paint and hardly worn as pbviosly I pull him he doesn't strain the chain. Sadly I managed to forget I left it in my garden through all the rain over the last few months. I'm gonna have to replace the real wheel take off the cassette but guess what. The chains immaculate!!!

[@simonsepic]

One speed chain rather than one by sorry

[@alexanderscott2567]

When your waxed chain is in need of service, disengege it, remove it, then reingage it for the service. This way, the quick link is serviced at the same time. It doesn't tke rocket surgery to figure this stuff out. When you are riding, your brain is free to do many things. Use it for simple things, like how to figure out how to maintain a chain, or flush a toilet, etc..

[@urouroniwa]

Inner tube rolling resistance: The rolling resistance is reduced by allowing the tyre to deform to the bumps. This means that you aren't causing the whole bike to move up and down. Moving 80 kg up even a few mm takes a lot of energy. The easier it is to deform the tyre, the less energy is used to move the rider up and down. The deformation of the tyre is mostly a function of the tyre pressure (less pressure is easier to deform than more pressure) and the compliance of the sidewall. When the tyre squishes, though, it has to squish both the sidewall and the inner tube. So the overall rolling resistance has to take into account how easy it is to deform the inner tube! Latex tubes stretch much more easily than butyl tubes which is why they reduce the rolling resistance of the tyre and also provide better comfort. Or at least that's my current understanding. Tomorrow I might think that's all bollocks, but today it makes sense to me 🙂

[@JonCannings]

Yeah, it makes sense plus it's why traditionally cotton side wall tyres were a smoother ride, as they tended to flex more when encountering a stone for instance. The tyre would temporarily change shape to go "over" the stone. Whereas a cheaper less flexible tyre would be a harsher impact. Easier to explain visually than through my terrible writing! 😂

[@benconnor4848]

Jon Cannings!!!

[@playandteach]

Waxed chain on a long trip - better hope it's dry weather. Also with the Silca top up wax, aren't you supposed to wait 24 hours to ride again? On the question of hands free veering - rider position could also be a factor.

[@RenAigu]

I hear many people let the rear wear, then put the front on the rear and than a new tyre on the front. This way you always have a fresh tyre on the front. Many say that grip on the front is more important than on the rear; front slips you eat dirt, rear slips you can often safe it by your momentum.

[@gcntech]

Great point! As a money saving tips or in a pinch this can be done but a fresh set of tyres is always going to be the best option 👌

[@RenAigu]

@@gcntech Yeah, but in my experience the rear wears so much faster than the front, visually at least, replacing or essentially throwing away a only ~ 5% worn front tyre because you want to replace your 80% worn rear tyre seems wasteful, not only economically. Before a race or long adventure sure, but as a commuter or just riding in the local area I don't see the point

[@RelakS__]

Wax and quick link. I just put together the whole chain then how wax it. When I put it on the bike, I do not remove the quick links, and also take enough care to keep the half links in the chain. This way the wax may not fall out of that pin.

[@tychoMX]

Yese, YES!!!!!! Yay Jon!

[@skulluxe1]

Bike veering to the right could also be the camber of the road… depending on what side of the road you are on… roads are slightly angled to promote drainage of water off the road to the side to prevent pooling. Depending on how much of an angle it could affect your bike to pull to the side. Even runners get an injury due to the difference of running on the slight cambered angle…

[@JonCannings]

This is very true! In the UK our roads are in such bad condition that there is no camber, they're full of holes 😔

[@tamarastrulik7419]

#ASKGCNTECH Hi Guys, I'd like to know if you can confidently recommend from your own personal experience any shoe covers that are actually water proof (not just 'waterproof' as stated by the brand). My shoes are Specialized Torch 3.0's and I've tried multiple shoe covers that claimed to be 'waterproof'. After one or two rides in properly wet weather, my feet get almost as wet as when I wasn't wearing them. I have also taped the little vent on the bottom of the shoe shut to prevent water from getting in there, and it didn't prevent them from getting soaked. Thanks!

Re the bike which won't go in a straight line, you missed the obvious. The camber of the road means it slopes toward the gutter. An externally cabled bike as you said is the other reason. On gold chains or any other plating , it definitely stops rust

Jon’s back with his straight forward answers! Oli do you dream of waxed chains??? Your obsessed.

[@markp353]

With all due respect gentlemen, (and I respect your expertise and your wealth of knowledge and have learnt a lot from you both) but your advice on tyre swapping on this occasion I believe is incorrect. IF you are replacing only one tyre, regardless of how much work is involved, you ALWAYS put the best tyre on the front. Unless you have just replaced the front tyre and it only has 200-300kms on it. Your front tyre does most of the braking and has the most influence when cornering and keeping you upright. Take your car for example when you replace two tyres only, where do the mechanics put the new ones even if it is the rears that are worn - on the front. Why, because it is SAFER, provides greater cornering grip and provides you with the best possible braking performance. Why would you not want this when riding your bicycle.
