When your MTB gears are working smoothly you hardly notice that they are there; each shift crisp and positive, allowing you to power up the climbs and sprint into features. When they’re not working, on the other hand, it can drive you insane. Crunching, grinding, clicking, skipping, an absolute nightmare. Here are all the issues or problems that might be causing your gears to skip, and how to solve them 🔧

@dansotelo228 3 года назад

As a professional mechanic since 1967, this is the best video I have ever seen explaining to pro & average MTB & Road the reality of derailleur problems. Please follow all his advice, but I do want to add a little bit more which will make all he is saying to add a 50% advantage on how to keep your bike working like new. The first rule, modern narrow chains like 9, 10, 11, 12, and now 13-speed chains only last 400 ~ 600 miles, especially MTB. The second rule, a chain only recognizes Miles and not Time. I can't tell you how many times I hear from Pissed Off customers saying "What do you mean my cassette and my chain are ruined, I just bought my $4000 Cervelo or $6000 Yeti 3 months ago"!! In those 3 months, the new bike could have been ridden from Seattle to San Francisco and back. Or basically hung in a garage and ridden lightly on 2 weekends. "MILES", you need to keep track of your miles on the chain. Cassettes are very expensive, chains are not. So here is my advice, whenever you see your type of chain on sale, purchase 2 or 3, and just replace them at 600 miles, "no matter what". This way you can extend the life of your expensive cassette more like 4 or 6 times longer, instead of 3 like this video advices. There are two chains on the market that honestly last 1000 ~ 1500 miles, but they are expensive, KMC Diamond, and Shimano XTR/DuraAce chains. These chains are expensive because they are very hard to make, as their secret to a long life is they have polished pins and link plate holes.

@MehYam2112 2 года назад

On a new system, I'll buy an extra chain or two, and have a routine of swapping chains regularly as I clean and relube them. This way, you're not buying and installing a brand new differently-lengthed chain in the middle of a transmission's life cycle, instead, your set of chains and cogs and wear together until the entire lot gets replaced.

The limit screws are not "responsible for the indexing of the gears to work correctly". They do exactly as their name suggests and sets the outer limits of movement to stop the chain falling off of the cassette. The cable tension is responsible for correct indexing and position of the derailer relative to each sprocket, and this is altered with the barrel adjuster.

@p.richardssr.3137 2 года назад

Going to try the cable adjustment....1st, when i get skipping gear while in motion.

@13ballom 2 года назад

Limit screws do affect indexing. If you back off either of the two limit screws even 1/8th a turn on a perfectly indexed bike, it completely ruins your shifting even if it doesnt throw the chain off on either side. Imagine indexing as a set of straight parallel lines being drawn through both pulleys and the sprocket, turning the barrel adjuster clockwise or anti-clockwise moves the entire set of lines to the left or to the right, the limit screws limit how far left or right those lines can go, so when u set your limit screws wrong you essentially allow the set of lines to move further in one particular direction which messed up your shifting.

@brygry 2 года назад

@@p.richardssr.3137 is this any gear and all the time, or more prevalent in higher gears when putting the power down? This initially sounds like a worn out cassette where true chain jumps in the highest gear.

@SnootchieBootchies27 3 года назад

Thank you for properly explaining chain wear. I've been telling people for years that chains don't actually stretch but no one listens to me. P.S. cables don't stretch either...

@peglor 3 года назад

They both stretch elastically but spring back as soon as you take the load off - unless your torque output is at monster levels :-P. With cables I reckon it's more the ferrules seating into the cable outer than any issue with the cable. It's why a newly installed cable outer will almost always need tweaking during the next spin, but a new cable in an old outer is usually set and forget.

@bradcloud7670 2 года назад

I was looking into my brake wear and cable shifting issues. My ferules have been abraded? and my cables catch in it. Time for new housing. I ordered new cables anyway, but wanted to agree with you.

@SnootchieBootchies27 2 года назад

@@peglor yup, this is exactly what "cable stretch" is. If you properly seat the housing into the ferrules by stressing it upon first installation, that initial readjust for "cable stretch" is no longer needed.

@denniskoh4940 2 года назад

Yup-- I get so annoyed because the first thing I hear is "cable-stretch". Always prep the ends during installation. I cut away 3-4mm of the plastic outers and grind the end flat before jamming into the ferrules.. Hardly ever have to deal with that "cable-stretch" issue in the past 15 yrs or so since doing the preps on all my bikes .

@alexguir903 3 года назад

Your explanation is so on point. I have never even tried to touch those components (riding for about 8 years now) because I have no idea how they work (plus I haven't been interested on doing maintenance my self, I would just take my bike to the shop) but as I am about to upgrade to a new bike I am getting to understand the different components. This video is great it is giving me the confidence to get some grease on my hands. Thank you.

@hawleygriffin1800 2 года назад

Twice I've had a skipping problem on two different bikes 10 years apart and both times it was caused by a chain pin that had come out of the inner half of a chain link. Caused first time by shifting under load on a hill causing the chain to "slam" into the next gear. Second time I am convinced it was caused on a gravel road and a rock going through the chain and sprocket. Both times the chain was only held together by the chain pin staying in the outer half of the link. It effectively makes the chain too long because the chain is only partially connected and can flex horizontally. Riding feels like the bike wants to shift and starts to, but will often stay in the same gear. Used a chain tool to drive the chain pin back and re-seat it.

@peglor 3 года назад

A great summary of just about everything that can go wrong with gears - probably the only thing left out was to check the jockey wheels for ridiculous slop in the bearings - historically it was never a problem with the ceramic bearings Shimano used to use, but their cartridge bearings get very sloppy very quickly by comparison. I used to be able to get 2-3 drivetrains out of a set of jockey wheels at which point they'd still shift fine, but have almost no teeth left, while with the 12 speed cartridge bearings, the wheels look fine, but are tipping 10-15 degrees off vertical when they get side loaded. They surprisingly still shift gears pretty well, but the shifting gets very laggy and sloppy, and 12 speed is bad enough to begin with for anyone used to the light snappy shifting feel from 8-10 speed shifters. This is the only video I've ever seen that even mentions what the upper gate on a chain tool is for. Topeak are about the only company still making chain tools with this feature at this stage, mostly because the bike buying public for the most part have no idea they're missing such a useful feature when they buy other chain tools.

@tychoMX 3 года назад

Hard to attribute generalities from 4-8 specific examples here. My money is on GMBN esp. if Canning is not participating. That said, from someone that does both suspension is very specific and I’d say many MTB mechanics can’t do more than the basics. Roadies would be totally lost. But I know also who would be more likely to glue a tubular properly (a ‘cross mechanic :).

@vinny61389 3 года назад

Wow. This was pretty comprehensive. Fantastic guide! Generally speaking this is the order in which I troubleshoot as well. Only thing I put earlier on in the process is asking/checking how old the cable housing/cable itself is. I can't count how many times it boils down to internal resistance in that housing that is the cause of all the problems. Mud, grit, and rust just love to hang out in there over time, especially if frames have any sharper angles on internal routing.

@jimig399 3 года назад

I agree completely. 40 years of riding shifting drivetrains and 99.9% of the time it's at either of the terminations. Either the barrel at the mech gets wear on the cable or the other side the cable housing at the shifter end gets pulled up and thru the ferrule and mangles that end making it snag so you don't get clean shifting. So sick of fighting this that I can't tell you how happy I'll be when we can finally ditch the cables for good. Can't believe we're still dealing with cables in these modern times. I've just seen AXS up close and it's not that impressive. We need some fresh ideas in this area and for someone to come in and completely reinvent it as if it shifts by magic or so you just think about shifting in your brain...and it does. That'll be the day I'm happy.
