RJ The Bike Guy first video I've watched on how to fix a bike and it's been sooooo helpful!! 🚴😊 Thanks 😁👍 Sub'd 🤓

[@HerrenGamingNews]

Hey bud just watched your video I got a weird problem If I shift up past 6th gear my bike's chain will slip until I shift down. I can shift all the way to 6th but not further. I bought the bike 3 days ago so it's brand new is there a break in period?

[@RJTheBikeGuy]

@@HerrenGamingNews If you just bought the bike, have the shop fix it. Sounds like a limit screw adjustment.

[@HerrenGamingNews]

@@RJTheBikeGuy yeah I just talked to them and they said it could be the cable, next time when I buy a bike I'm going to get them to check the gears, cable and chain on top of their safety inspection which will be in 2021 as I want a fat bike for the winter

[@anuar.m.y]

i am in dire need of help! my bike tries to kill me on 3rd, 4th, 6th and 7th gear, i make sure i down shift and "seat" gear properly before putting pressure on the chain while climbing, and the chain "skips" meaning that it feels like the chain lets go 100% or af it the cassette has missing teethe and you get to those teeth and it lets go for 1 second, not good when you are putting all your pressure on the pedal and just goes "CLING!" and all your weight goes sideways!! the bike never did that new and only after a few rides i start having issues with it and never had worked correctly after the first tune up..

Hi RJ: Update on my chain skipping problem on my 3x9 touring bike: Turns out that the culprit was a worn middle chainring! Everything else is new on that bike, so I should have thought of the chainrings earlier, but when you're stomping down on the pedal while riding it's impossible to keep a close eye on the movement of the chain. It was only when I asked my wife to look at the cassette while I stomped on the pedal with the bike on the floor and the brakes set that she exclaimed, "the cassette isn't moving, you dummy!" This has proved to be one life lesson that I will never forget....

[@Tailspin80]

I have a 17 year old hybrid with a 3x6 freewheel setup. Shifting was awful. Changed the chain and freewheel but not much better. The main culprit turned out to be the rear derailleur which has lost a lot of its spring so the chain tension was too low. However carefully the limit screws and indexing were set it would not go up and down reliably. A new one completely fixit it. I had a second problem of shifting getting slow and sometimes delayed for several seconds. This was due to dirt getting in the cable to the rear derailleur. The cable comes in three outer sections so lots of places for dirt to get in, but easily cleaned as well. I have a new bike now with Shimano 105 groupset. The technology has come so far in the last 20 years, it’s in a different league.

[@peteferraro4632]

Thank you very much for this video. I bought a used Trek 7.4a few years ago that had a persistent problem with the rear derailleur. It just didn't shift as smoothly as it should. I tried the standard adjustments. I took it to the LBS. All without success. Then I found this video. It suggested replacing the shift cable. I replaced the rear derailleur shift cable and wow! Problem solved! Before I threw out the old cable, I inspected it. I found a kink in the cable that would explain the poor shifting. Thanks for the great videos. Please keep them coming.

[@RJTheBikeGuy]

Your LBS didn't catch that???

[@peteferraro4632]

Sadly no. I have since learned that not all LBS are equal. Some are more new bike assemblers that bike fixers. The good news is that since the LBS experience, I decided to rely on my own 2 hands. I bought some a bike stand, some tools and have since refurbished a few vintage bikes. All the expertise I needed was in your videos. I've also founds a new LBS for the stuff I'm not yet up to fixing. Thanks again for your videos!

Excellent video. My well used bike was working fine, but I thought it might be time for a new chain. The bike mechanic told me the chain was so worn I would have to replace the sprockets..but I didn’t believe him. They looked okay to me. But after fitting the chain, I literally could not move the bike, as the chain slipped freely over all sprockets under any load. Amazing! As the bike is old, I have refitted the old chain and everything is back to normal. No skipping except on the smallest rear cog.

[@drchris103]

Those binding chain links can be a real 'gotchya' situation.

What a lesson that was.... and that was with a new chain as well, surprisingly.

Nice video. One other thing that can suddenly cause bad shifting on a bike that has been shifting fine for a while is a worn (even busting) cable or bad housing. Sometimes hard to see if the cable strands are starting to bust up inside the shifter.

Great video! I have a bike that was locked up outside in the elements for a long time without use (thanks a little to COVID and a bit to the weather). I immediately relubricated the chain but found it skipping. The cassette , derailer and chain seems to still be good. I'm now under the assumption that the chain links are stiff (due to being out in the elements for so long). I used some oil to continue cleaning them. Otherwise, I might just replace the chain. Thanks for the help and tips!

[@David-ty5jk]

You should get a new chain and pay to get it placed on. I'm telling you no amount of money saved is worth attempting to do the chain all alone if you deal with links. You can follow the instructions all you want you won't get nowhere and with some skill and determination you might take a few links off the chain but you will never be able to put the chain back together without an actual machine or taking the bike to a shop where they can do it by machine

Just cleaned up my sister in law's old mountain bike and put a new chain on an old Shimano 7-speed cassette. Jumping like crazy on the three smallest sprockets. Was thinking I might have an incompatible chain ( KMC Z50 ) but worn sprockets sounds like the real cause. She always rides the middle chain ring on the small sprockets. Need to see if I have another 7 speed in the collection ( think they are all 8 though ).

[@bryanburnside9783]

On line with frame flex shifting issues, I have found that worn bushings or bearings on full suspension bikes can be a serious issue. So, if you have a F/S and it is still jumping or ghost shifting after going thru all the common fixes, check for suspension wobble.

[@willek1335]

Mine skips on the highest 3 gears (3 smallest ones at the back). 7, 8, and 9. It's a brand new 1500€ bike too. 2 week old, so it shouldn't be wear and tear. I suspect the problem stem from that time when I biked home from the bike shop, obviously excited with a big smile, I hit the tram tracks and rolled over on my back. No real medical issue, more so my pride, but that probably bent something on my bike somewhere. Then again, the problem with that theory is that the gears didn't start to jump until several days later while on a cross country trip with lots of luggage in a bike cart/trailer. Now it jumps while going straight on flat ground with hardly any pressure at max speed. That was too much information, but the point is thank you. You've at least helped me narrow down the issue considerably. :) Cheers from Norway

RJ, First, thank you for all of the great videos! I’ve been able to get into maintaining my bike w/ them! Second,, I’m a newbie so apologies if my terminology is inaccurate. Finally, having an issue post-overhaul of my 1991/1992 Bridgestone MB-4. The drivetrain is slipping (forward, not across gears) in select gear combinations when solid amount of pressure is applied pedaling, especially uphill (i.e. middle front gear w/ second smallest rear gear). Some gear combinations seem ok. Wasn't able to figure out cause from this video. Replaced original chain with KMC Z51 Bicycle Chain (6 & 7 Speed , 1/2 x 3/32-Inch). Front crankset/chainrings are original: 24, 36, 46T Original cassette was: Shimano 7 speed cassette ((Shimano CS-HG30-I am). 11, 13, 15, 18, 21, 24, 30T. They no longer make 11-30T. Replacement cassette is: Shimano CS-HG50 7-Speed Cassettes (13-15-17-20-23-26-30T) I quadruple checked chain length/links against the original and new is same number of links but a tad bit shorter due to stretch in 25yr old chain. Could it be that I put the front chainrings on backwards during overhaul? Do I have a chain/cassette/crankset mis-match? Thanks in advance! Regards, Jeff

I can't tell you anything without working on the bike directly. It is likely something in the video. Maybe adjustment or worn cogs or something.

Anyway, I noticed the pulleys aren't in a straight line, the tension wheel seems to be 10mm further in than the guide pulley. An easy fix, but I needed to know whether it needed to be in a straight line. Thanks for an informative vid 👍

Very useful, but what about the chain slipping on the chain wheels? I replaced the chain and freewheel/gears on my MTB, but chain still slipped, but not as badly. Replacing the chain set sorted the problem. The chain slipped on the middle chain ring, but not the largest, presumably because It was torqued less. Is chain slip less likely to be caused by a worn chain wheel than a gear on the freewheel?

[@reecenewton3097]

My new chain slipped with the original freewheel and middle chainwheel, on a front triple crankset. The middle is the one that I had used most. The large (high speed) and granny (low speed) were used less: they were still operable, but the middle was pretty bad when I inspected it closely. It's an aluminum alloy, softer than steel. The cogs on the freewheel are steel and still have their factory profile. So I replaced the middle chainwheel and the problem went away. The exact same thing happened with a friend's bike, and he replaced the middle chainring also. So you really have to check all three areas: freewheel, chain, and chainrings. A chain and the cogs wear together, so sometimes a new chain won't work well because it doesn't mesh correctly with the old cogs.

I know this video is old, but just in case this happens to help someone out - I had the chain keep jumping gears without me getting anywhere near the gear levers. I took it to 4 different repairs and they: 1.) Replaced my chain 2.) replaced a part that I don't know how to translate - maybe the bearings that fit through the back wheel? 3.) shortened the chain by 1 link even after the first repair shop charged 50 bucks for the first 2 fixes, probably getting it right. The logic was that the chain might be a bit loose and that's why it jumped. 4.) Adjusted the rear derailleur 5.) a couple other things that I can't remember At the end of the day, the problem persisted and it made me hate riding my bike, because during riding, the chain would just skip gears, the pedal would lose resistance and my leg would push through unexpectedly and violently, hurting my knee badly sometimes. Took it to one last guy before giving up on the whole bike, and all he did was replace all the cables and cable housings, and it's been working for months on end without a single hitch now. Hope it helps someone!

[@7binus9]

Just to add a statement, because I don't wanna give misguided information: I know the guy who actually fixed the bike's problem ALSO adjusted the rear derailleur (I quote him that he only adjusted it "a little bit"). That means that it could've been the reason on its own the entire time, and that the first person adjusting it didn't tune it perfectly maybe. I don't know how big of a role the changing of the cables and cable housings made, but I hope it's also a valid contender for the list of possible causes for this particular problem. Anyway, best of luck to anyone dealing with this! Thank you RJ for helping everyone with your wealth of knowledge and experience!

I had similar issue, replaced old 8 speed chain with new one but the new one was slipping. The reason old was replaced because it visibly extended because of large play of every link. The bike is relatively new (about 1.5 year) but used every day or total of about 3500km. The cogs looks ok as well as derailleur, but the crank cog is not (teeth have visible damages similar to what you described damaged rear cogs). Interestingly the old chain (no slip) although not as good as it was on new bike

This is a great diagnosis video but is a poor "How to" video that the title suggests that it is.

[@alecnolastname4362]

How to diagnose, not fix. I think my cassette needs replacement and i bought it like this, back to the store with complaints.

[@niilespunkari8832]

It a bicycle, not a motorcycle, start screwing on something at some direction, and it will work out.

[@DRDINOMEOW]

I figured out what’s wrong with my bike. And how to fix it from this video. Also he tells you about his other videos with the solution to your diagnosis. Use this video figure out what’s going on, and use his other videos explaining the problems and fixing them in greater depth

Helped me fix my problem with, great video.

@@alecnolastname4362 Ah, that's why the video is titled How To Diagnose Bike Chain Skipping/Slipping/Jumping Gears

[@lewtus72]

That was actually pretty useful. A lot of these aren't... Lot of good points to check for bad shifting

[@adaumisasmr6620]

question, I just bought a bike😀, was riding, braked, brakes work a little too well lol, and I ate it with the bike and the chain fell off... Its a 7 gear bike, idk if thats right, anyways, I put the chain on the second to smallest cog, and then on the smallest, is that correct, if I have my bike on number 7??

[@samhaven4562]

Yes

[@x2oChannel]

Great video! I'm trying to repair my wife's E-bike fitted with a Shimano Deore, 10spd cassette with KMC X10eT chain. She has over 3,000 miles on it and the chain had a 1/16th in stretch, so we just installed a brand new chain (same KMC as new bike). Unfortunately, the new chain jumps under effort, and any adjustments to the derailleur did not help. 👉Is it possible that, in this case, the cassette would also need replacement?

[@RJTheBikeGuy]

Very likely.

[@x2oChannel]

@@RJTheBikeGuy I replaced the cassette and also the front chain ring: All IS GOOD NOW! Thanks

My gears skip on gear 6 and 7 mostly when I add kore force/pressure going up.
