If you want to extend your dropper post life use a rear mudguard. I don't get why so many people (especially in wet muddy countries) don't run one. Sitting on a wet muddy saddle feels awful 😂

I have a set of those classic Intense Metal Tyre levers for when I really need to get a tyre on or off... that said, I've not had to use them for a fair few years now (it used to be Halo rims and High Rollers which gave me headaches...). Snapped a lot of plastic levers in my time though.

I find if you're having trouble getting a tire off a rim just heat up the tire. Either leave the tire in the sun for a while or use a heat gun or hair dryer to heat the rubber to make it softer and more malleable.

I've had plastic levers but struggled to get road bike tyres off (and some mtb tyres) so went back to metal. I find they're fine for just getting the tyre off in the first place, but then I use a plastic one to run around the rim to prise the tyre off. Talk of putting holes through rims just seems ridiculous unless you're completely inept.

Thanks for your insight. I agree it is hard to imagine - but alas I have seen alloy rims with holes punched through from metal tyre levers - the inner rim bed profile is often thinner than you might imagine - so agreed it might seem wild but it can happen. Again thanks for your insights! Cheers Owen

If the anodizing is worn on the back of the dropper, it's probably at least in part due to the angle. You can probably help prevent/minimize the wear by not using full body weight when using the dropper and/or shifting weight to the rear of the saddle and pressing forward with the hips a bit to help keep all forces in line with the seat tube/dropper.

#gmbntech I once asked a bike-fitter how wide should the handle bars be? They said that just measure your shoulder width + the width of both palms = the "ideal" bar width. So basically, it's you best "push-up" position. No aches on the trapezius or deltoid muscles or forearms up to the wrists as well.

I've had to use metal levers, small ones, with the first removal of a tire. Mostly because the plastic will NOT get between the bead and rim bed. Usually end up tearing the rim tape with the plastic making the attempt.

So many factors in cutting handlebars vs changing stems, it will be interesting to see how everything works out. I agree that changing one thing at a time is a must, but I would also add writing it down and keep track of feel etcc... if it ends up being a situation where there are several changes over a bit longer timeframe, it may be easy to remember how a certain change actually felt. On another subject, I have always used plastic Pedros levers. They are very strong, and I think in over 30 years of shop work... I have broken two. But as many know, it's truly about learning to install tires correctly, and moving the tire around to give you a bit of an advantage. But, some certainly a re a bit difficult...

@@Sai-tb1xt it’s actually both. Both terms stem from the word alumina and were coined around the same time in the early 1800s. North Americans prefer aluminum where the rest of the English speaking countries prefer aluminium. Additionally, calling carbon fiber merely plastic is akin to referring to cement as concrete. Colloquially, sure, it’s roughly the same. Technically, carbon is a composite material.

@@dkumagai30 you are so close,... carbon in itself is nothing more than an element, the combination of layup of carbon fiber mats and hardening with composites makes it what we call carbon composites. also with aluminium, googling and taking the first hit as fact is mostly only half the truth. calling it aluminum is just plain wrong in a scientific sense,... i like to hear you say potassum or strontum, ...polonum anyone? if the us-americans want to get rid of the u in colour, that's fine,... i am not an artist, but insisting on mispronouncing technical terms is something that is the same category as using feet/inches/thumbs and noses for measurements, just because you can doesn't mean you should

#AskGMBNTech Hello GMBN. My question is regarding older 26 inch suspension forks, specifically ones that have cantilever/V-brake posts. I am resurrecting a late 90's mtb and it looks like I will need to replace the fork, as the one that I have is no longer supported. What brands/models of used suspension V-brake forks (preferably higher end for the time) should I look for that are still supported (i.e. parts still available so that they can be serviced/rebuilt)? Keep up the great work!

I'll second the idea of getting a slightly undersized brake adapter. I've seen many cases where the pads extend above the disc. This causes the pads to wear with a "ledge" above the disc that can eventually make contact with each other and prevent the brake from working at all; very dangerous. At least when the pads are properly aligned, there will still be some braking force even when the pads are worn out of spec.

Hiho, there is a specific postmount adapter available directly from Hayes converting 180 to 203mm. Just beware which rotor is used, some may require an additional 0,5mm washer on the rear screw to fit the brake pads perfectly to the rotor (e.g. Galfer rotors)

One caviat with adapters though, most of them don't have full specification in their name or in online shop description. Like, Shimano SM-MA-F203P/PM is for 203 rotor. But you have to dig up thedocuments to see it adapts from 180 originally. And there is SM-MA-F203P/PA which mounts onto 160 spacing. Or there is Sram with spacing measurement and Magura with diameter and a model number that can be mistaken for spacing, etc and so on...

There are some myths floating around the bike world that are not true. One of those is, really high bars take weight off the front end. That is not true, especially if you redo your sag measurements. Another myth is shorter stems make a bike steer faster. Everything else being equal, this is not true. What it will do is make your steering less twitchy and make your bike more stable. that’s because it provides less leverage on the steering tube.

My question is: If I long stroke my EXe shock from 60 to 65mm shaft travel (it fits), should I set the 30% sag using the 60mm figure or 65mm figure? Or I guess what I’m asking is, is sag frame dependent or shock dependent.

Great to have your insights Your right with the right technique hands - strong hands - can be enough to remove a tyre and fast - however - from personal experience - in the work shop here at GMBN Tech - and World Cup DH races as Mechanic - some rim tyre combo's do need extra help of tyre lever as - for many tubeless set up's - having a tight rim to tyre bead interface can help reduce issues of bumping where by the tyre bead can momentarily move away from the rim bead and you can lose air. So for some tyres even strong hands aren't enough. Again thanks for your insights Cheers Owen
