Bike Chain Skipping While Pedaling Hard | Solved | Solution in Description

[@theBidon]

SOLUTION: If you replace your chain and cassette, and the chain still skips, your crankset or chainrings will most likely need to be replaced.

[@theoneandonlykk777]

nonsense

[@Jake.reeves]

Hmm, changed crank set and got a new chain. Same issue.

[@ivorybutcher6328]

You should buy a groupset of bicycle parts from the same brand and model, not different. So the parts will work smoothly.

[@adjmbb5109]

Mine does this brandnew

[@BrandXsps]

Had the same problem after replacing a chain that broke. It was noisy for a long time and my solution was to wear headphones. Then the chain broke. I replaced it and it and started having the skipping problem on the three cogs I spend the most time on. On closer inspection I noticed the teeth on some of the cogs were worn to a sharp point and didn't have a flat top anymore. New cassette fixed the skipping and the noise. I still like riding with headphones though.

[@gerrypete7040]

My fix was simple. I had washed my bike according to the Park Tool KZbin video "How to Wash a Bike" and apparently didn't center the rear wheel properly in the seat stays when I reinstalled it. There was no noticeable issue during light load on the cranks but when I began to climb a steep hill I experienced the skipping, slipping and jumping gears shown in this video. I inspected the rear derailleur, chain, cogs, and chain rings and could not identify any noticeable issues, but I saw that the real wheel was not perfectly centered in the seat stays. I centered the rear wheel, climbed the same hill and experienced no skipping, slipping or jumping gears. I could not imagine attempting the identify issues with the bike components given that the fix was simply centering the rear wheel.

[@scottthomas4814]

This seems to be happening every day on my way to work and I work shifts, honestly feel like throwing the damn thing in the canal😡😤

[@joerivankallo]

Always replace chain together with rear cassette. When the chain wears it damages the teeth on the cassette, and when the cassette has wear, it stretches the chain. When you replace both and the chain is still skipping, it is actually not the chain skipping but the hub (where the cassette is put on) that has a lot of dirt inside, causing it not to "bite" in the wheel. Search YT for a detailed video on how to do maintenance on your hub. No need to buy a whole new bicycle :) Oh yeah, and by the way... Avoid taking off on the smallest rear chainring. It puts all your power on 6 teeth (11 in total where only 6 have contact with the chain). Shifting to 2nd or 3rd gear before stopping is a very good habit which will make you spend less money on chains and cassettes.

[@montoyatony778]

Niels clooster thank u so much I really appreciate the info I have a silver 2003 giant revel medium and I replace the chain the cassette the crank and still doing this but my hub is making a slight crunchy sound but I guess I'm gonna have two replace hub plus all the new stuff I just put in it and maybe the bottom bracket

Alright guys I’m new to this mountain bike stuff you mean to tell me nobody here can trouble shoot this and have a rundown of things to check. I’ve worked on motorcycles for years I’ll either figure this out on my own or put a motor on the stupid thing . I guess I have never met a bicycle mechanic I might have to educate myself on this and try and help you fellas out . I’m not a parts changer things should have tolerances and measurements of good wear and bad wear on sprockets or what ever y’all call them . This it crazy it a stupid bicycle for Pete’s sake can be that complicated. I’m not going to Throw parts at the dang thing and hope it works got to be a better way to diagnose this issue.

Rear cassette

[@radiocontrolled9181]

​@@LeexfamThere is only one cassette. And that's at the rear. The front parts are called chainrings.

[@battistaverardi1240]

B limit screw. Make sure your top jockey pulley is not interfering with your cassette. You need the perfect amount of space in that area. Not to much and not to little. And yes worn out chain rings can contribute to the problem but not 100%. Everything needs to work in unison. Unfortunately this can be a mystery but it can be solved.

[@NunalSaPaa]

I recently got a narrow-wide chainring for my mountain bike and that's when the skipping started. It's really frustrating. There were multiple occasions I was off the saddle while climbing up a hill and the chain slipped, I almost went OTB.

My issue was simply kinked chain links. Made a popping sound. Put the bad links I had a few, onto a chain breaker. I then just applied some force back and forth on the link pins, not driving out the pins. Applied some fresh lube to the links, tested the up and down motion on each link with my fingers and just like that a functioning link once again! They inner and and outter link plates were not bent so the links were good. Hope this helps some!

[@eddier9593]

Just bought a new Shimano XT chain and this happend to me yesturday when putting the power down on the pedals, ( happens only on the smallest cogs which are used 75% of the time) So after changing the ( well used ) XT cassette and re-adjustment the problem was solved! Generally a new chain will not perform well with a used up cassette and vise-versa, a warn chain and cassette will probably work better because both components have molded to each other's wear throughout it's life, it's pretty damn important to match your chain to the gear number you're running.

[@jowen85]

old chain back on, and put it down to experience

[@matoatlantis]

This is what I was dealing with yesterday. I had this problem after I changed the 3 years old chain. It is worn out, my bad I didn't take care of it sooner. The thing is everything works flawlessly with it (it's really smooth and silent ride), it's the new one that has a problem. No wonder, as you said, components have molded to each other's wear. Now the dilemma: do I start replacing my XT components or let it be ? If only I can test run new components. It almost feels not worth it. New cassette is around 70EUR, but cranks are about twice as much.

[@eddier9593]

@@matoatlantis Yes, you're going to have to replace the cassette as well, but it's a good excuse to buy new parts for your ride! If you want your chain and gear components to last longer then intended, you'll need to clean and Lube every other ride to get the most out of your new gear.

[@matoatlantis]

@@eddier9593 Well, I've Deore XT m8000 group set, I'm happy with it. Cassette is cheap-ish, it's the cranks that makes this fix more expensive. While 200E is not a horrible amount, it feels like wasting money. And it does work nicely with the old chain. I did 1km vertical climb on it today and it was flawless. I think these cranks and cassette will die with the chain. :) I did lube it, but yeah, I neglected to check it periodically.

[@harveyjoneswoodsman5956]

But what if the chain cassette and derailleur are new and it does this shifts excellent but jumps in the 11 tooth gear when torque is applied

I replaced the handlebars, stem, forks, calipers, gear cables, wheels, free hub, crankset, cassette, dropper post, seat, grips, carbon frame, inner tube, tyres, rotors AND the pedals. After all that it was fine again. No thanks needed, i'm just glad i could help.

I am glad I read some of the comments on bike chain skipping under load. My bike chain, specifically the fourth gear, started going crazy only after I had my gear shift cable replaced. Nothing else was changed, just the gear shift cable. I am thinking the fix, in my case, must have something to do with the cable, I mean, what the new cable affected. Any ideas?

[@KimonFrousios]

I have a stretch-measuring tool, and change my chain when it reaches the marked stretch point, which is basically annually. For the past 3.5 years that worked out fine. Not this time though. The new chain just skips whenever I need to put in power. Adjusting the derailleur tension made no difference. The chainrings and cassette show no notable difference between the cogs I use a lot and those I don't, and there is no problem shifting.

[@idbhai]

I have a new chain and a new derailleur ,its doing the exact same thing...Any fixes as the cassette teeth are in good condition too...I can't diagnose the problem any suggestions..

@@tristanhagel742 well I took to LBS, the guy there told me that I had to change my cassette which wasn't available locally (charms of living in a third world country, apparently freewheels on every bike here).... SO I ended up not changing the chain.. the chain eventually ground its way into the cassette teeth.. which increased the ride quality and made the chain slip much less.. another thing that I found helped initially was that instead of shifting down from say 7th to 5th gear .. I would go down to 4th then shift up to 5th.. Spookily worked like a charm the chain did not slip when doing this.. So it's been nearly 3 months I ride almost everyday and even though the chain slips but the frequency is far too les for me to get worried...

[@neilfox1759]

Bro did you get any new bike?which one

Definitely the cassette. I have the same problem now on a low end trek mountain bike. When you watch your video closely, when it slips there doesn't appear to be any violent slippage motion of the chain. The gear teeth on the cassette appear in very good condition. think how a cassette works. You can peddle backwards freely but when you peddle forward a mechanism is engaged to lock the cassette gear to the wheel. That mechanism has failed.

[@jowen85]

that's the freehub then, not the cassette... but doesn't explain why it would only happen in one gear

[@danfuerthgillis4483]

Tips: old freewheel ( or cassette) used up, with new chain = bad idea. Old rings with new chain = bad idea. New derailleur with old beat up Freewheel or cassette = bad idea. Biggest tip of all for chain noise is to check out the direction of the teeth on the freewheel or cassette as many cheap ones have the teeth facing the outside of the wheel causing chainrub. This happens quite a lot on cheaper hardware, solution is simple on a hard surface with a small flat hammer slowly pound the teeth into their proper shape as the other good cogs.

[@taze-1106]

I was cycling fast and hard down my local prom and the chain skipped and I fell off because it slipped, I went flying off the bike and bent my front wheel so I’ll definitely try this. Thanks!

[@beckzcrew]

Exactly what happened to me this past weekend on a fast group ride that I was visiting on a weekend getaway. Had put a new chain/cassette on days earlier, everything felt smooth in prep. Then, as soon as this ride headed out and the power had to be applied, that horrible slipping started. No way to work around that when the group is going hard out of corners and you don't know the riders, nor do the riders know you...#Fred. New chainrings on the way.

[@KimonFrousios]

@@jowen85 Chains stretch over time as the rollers wear down and develop play. Then the link spacing no longer matches the gear tooth spacing and the chain starts wearing down your cassette and chainrings. I didn't know about this until a bike mechanic pointed out to me the difference in wear between the gears of my cassette that I was using a lot compared to those I was not, after just 3 years of daily use. You can see the difference in stretch when you put a new and old chain of the same number of links side by side.

@@KimonFrousios well, the old wisdom, and proved by comments here, you replace the whole lot or you let it wear together. Recently tried changing cassette on a bike. Guess what, it skips.

[@KimonFrousios]

@@jowen85 If you have cheap cassette and chainrings, then yeah probably cheaper to let everything grind down to dust and replace the whole thing. If you have fancy expensive cogs, then you get a stretch measurement tool and replace the chain before it grinds your gears, with a new chain that is explicitly compatible with your chain set. I've had no problems changing chains with new ones of the same type. I've had problems using cheap SRAM chains on cheap Shimano cogs that are supposedly intercompatible (according to a bike shop that was trying to sell me the chain they had in stock). Even then, the chain eventually settled in and the skipping stopped after a week or so.

Worn cog on the rear cassette. If you put the bike on a stand, put it in gear and put pressure on the crank, you'll see the chain creep up on the offending sprocket. You usually only get this specific issue when you install a new chain with an old cassette. I had this exact issue on my BMC and to be honest, you can barely see the wear on the cog even when comparing to the new one.

I would take the cassette off - using a chain whip and a lock ring key and this exposes the hub enough to check the hub. If you ride in the UK conditions it might just be gunked up - if it's really gunked up the wear rate of the pawls will be accelerated so check they how look. I've got a set sat here for the exact same issue. Fairly cheap to replace but depending on the design and style of the teeth some take more wear than others. I use a halo superdrive hub the teeth are tiny on the pawls and they don't last so long in UK weather. I go through a set per year around 2000 miles of all weather off road riding. If you add a maintenance schedule to keep on top of hub cleans with a drop of light oil not grease then they last longer

Bad advice. Same-sounding problem with a brand new cassette, chain and chain rings AND a brand new wheel. The freehub started slipping after 100 miles. Easy way to rule out particular elements is to take the wheel off the bike and, using a chain whip, apply pressure while engaging the cassette (even a single cog wheel will do) to simulate pedalling. You may need to rotate the free hub (as in disengaged) back, then apply pressure, back again, and apply pressure at different points. It will slip if it is the freehub.

Was dealing with the same issue, everything is fine while peddling chain is fine as well as the rear free hub so long as tension remains. As soon as I stop peddling, the free hub in the rear something is catching and causing the chain to bounce and come off constantly. It was do to the rear hub being damaged.

But its getting worse to the point where i have to be in a lower gear then normal when accelerating from a stopped position. Ive tried adjusting everything and the only solution is less torque during acceleration. Since the bike is over 5 years old think i could still find the correct parts for it at a decent price? Or should i just pick up a different ride and hang this one in the garage? Love this bike and ride it 12+ miles almost daily. Its had a lot of use over 5 years but has always been maintained.

This is exactly what my E-bike is doing when under load on the last 2 small cogs 11T and 13T. I was told that those 2 need to be replaced instead of buying a whole new cassette. Problem is finding replacements for SunRace MS2 cassette 10 speed 11-40t. LBS says FSA chainrings are okay, Any ideas? Thanks!

Looking for a solution bought a brand new scwinn off amazon for 350 and this is already happening, seen some said about removing a link in the chain but didn't think you should have to do that or tightening the rd on a brand new bike and can't take it to a shop to be tuned as I didn't buy it at one. Any ideas? Currently having them ship a replacement, hoping it doesn't do this again

[@scstinger5]

I’m starting to think all bikes with derailleurs do this in the higher gears, no matter how new or aligned/tuned they are. I recently got a Rock Mountain Growler and as with all derailleur bikes, I am constantly re-aligning the derailleur hanger, adjusting the derailleur. The bike shifts perfectly because of this, but I still get some chain slip when pushing hard in high gears. On the other hand, I also have a old beat up single speed mountain bike that I ride a lot and it always works great no matter how hard I peddle or how bad I crash it. Long story short, turn you bike into a single speed and never have this issue again lol! That’s my plan anyway 🤙

[@robertbradley2420]

This happened to me after I changed my chain. So I changed my cassette, it case it had worn with the chain. Same problem. Just got back from my LBS. I was on the right track - my front chain rings had also worn with my chain, so I needed to replace those as well. To show me the problem the LBS turned the crank on the stand under load and you could see the chain slipping just a bit from the front chain ring. So the solution theBidon posted was spot on for me.

[@MARIN7785]

what if it happenes with a brand new bycicle?

Did you buy it from a bike shop? If so take it back and they should tune it for free. It is probably the derailleur.

Hi, I have now this issue. I have changed chain, crankset. All gears are changind smove and no sounds at all, but just you go peddaling and give more tention it happens as on your video. I really dont see that my rear cassette is worn (but maybe). How do you think, do I need to buy new cassette or first to try to change derailluer holder (maybe its bended)? Thanks

[@theBidon]

Hey, I would buy a new cassette. Sometimes you can't see the wear but it could be the issue. I did the opposite of you, I bought a chain and cassette. Then I replaced the crankset and it fixed the problem. Most of the time when you replace your drivetrain you need to replace everything, chain, cassette and crankset.

I just bought a used bike and replaced my chain because it was worn and it started skipping after replacing it.

[@gagatdja5653]

I bought the new cassete, Rd, freehub and chain together.. I got the common problem.. But old crankset.. Is it fixed if I replaced old crankset?

[@theBidon]

If the chain is the right one for the new cassette and the length is the same as before, the old crankset could be the issue. For me the chain would not jump if I placed the chain in the larger crankset ring. This was because I rarely used it and the teeth were in good shape. Once I dropped the chain down to the middle cog, the chain would jump with right away.

[@patrickoneill1011]

​@@theBidonMy issue was simply kinked chain links. Made a popping sound. Put the bad links I had a few, onto a chain breaker. I then just applied some force back and forth on the link pins, not driving out the pins. Applied some fresh lube to the links, tested the up and down motion on each link with my fingers and just like that a functioning link once again! They inner and and outter link plates were not bent so the links were good. Hope this helps some!

This problem happened to me two times when I changed my chain for a new one and let my old cassette. I cleaned the freehub body (everything, even the pulls, the 50 tiny balls and the cones inside) so I can remouve this problem and its still skipped. Probably a missmatch off the old cassette that is wornout and the new chain.

[@theBidon]

Probably so.. sorry you went through all of that. Hoping the new cassette works!

[@Colwray1]

I’ve got a similar issue , put new cassette, chain and derailleur on and now under pressure it skips at times under pressure (up steep hills).. but not worked out if it’s the back or front yet as it only happens when in the front little ring!! Chain although says compatible kmc 10sp.. does look a tad narrower on the inner links than my old chain.. think may get another chain and see if fixes it but very very annoying

[@theBidon]

Do you normally stay in the front chain ring? If so, you might need to replace it. It is causing your chain to jump. I replaced all the same parts you did and then discovered it was my front chain ring / crankset. Good luck!

[@Colwray1]

neverbikealone cheers, well I’ve just ordered this morning a new from 34T chainring... if that doesn’t fix it I’ve no ideas what else it could be... will update once replaced and tested ...

UPDATE: I've replaced the front 34T chain ring... and its now purring like a kitten again!! when i took it off to compare it with the new one, you could see that the teeth were around 30% or more in places worn down! so no wonder it slipped when the new stuff was put on... I'm going to also order and change the outer ring this week so they're both new.

[@StuffOffYouStuff]

I can't work out what exactly is happening, is the chain slipping over the teeth causing a grinding sound or is something happening internal to the rear hub? If it's the hub can someone explain the chain of events that's causing it i can't work it out? Thanks

[@sloemost5809]

Hasn’t anyone identified why it’s doing this? Mine is the same. Tho have a new chain. Has only just stared doing it. Old cassette, but find it hard to believe it’s doing it regularly all of a sudden, because the cassette is worn? Perhaps an internal hub issue? Sounds like the cassette is moving on the hub, or the cassette mechanism on hub? Really frustrating. Any help is much appreciated.

[@theBidon]

Typically you need to replace your cassette and crankset when replacing your old chain. The chain if used and not cleaned and lube properly over its life has worn into the cassette and crankset. I didn’t believe it could be the cassette and crankset until after I replaced them. I had the same thought it was something with the hub.

[@theelz1482]

it only happened to me after replacing the chain (its sized correctly (I tried 2 as I thought the chain was too tight & took a couple of links out too many and it still slipped) had a recent chain, cassette & derailiur change also) only happens when under pressure, less on the front large cog.

[@lampoyo]

Bike chain skipping/jumping after replacing multiple parts: Solution... just keep replacing parts until it stops.

[@whopperconduit]

So basically i have to replace everything to see the problem?? I have the same problem some time now, when I pedal a bit hard or going up hill my chain skip's... It feels really annoying because I feel like the chain is going to break..

[@theBidon]

Yep, you basically have to test each part of the drivetrain. Start with the chain, then cassette, derailleurs (if aligned properly), and crankset (or chain rings). Pretty frustrating, I know. In my case I replaced the chain, the skipping began, then replaced the cassette, skipping continued. Here I should have just checked my derailleur instead of purchasing a new one... bc the issue was with my old crankset.

[@whopperconduit]

neverbikealone when I read your comment I was already thinking "this is gonna get messy". Thanks for the info btw, I'm gonna see a doctor(mechanic) next week for a better check up.

[@JimnyVR5]

How would the crankset make the chain jump on the cassette? That can't be it

[@theBidon]

The crankset teeth are worn in compared to the new cassette. That small difference can cause the chain to not align.

[@619sharksnap]

@@snap_drama346 no, its more for fine tunings for each gear in the rear. So when you shft you turn the barrel and repeat that until all the gears are smooth. It prevents chain rubbing in-between the rear cogs. Tightening the cassette is easy though and I think its worth a cheap check. As I see no skipping in the chain from the rear cassette and also him stating himself he ended up replacing the front chain rings along with a new chain and rear deraliur after 5 years of neglect. You would have to replace all the parts by then. But...I'm sure he could've ridden for another 5 years on the old setup.👍

[@farturinn]

Hi, I've got a E-MTB with Shimano Steps cranks and SRAM cassette. The bike just eats through cassettes and stretches chains due to the added torque of the motor. In 3000km I've gone through 3 cassettes (mainly the smaller cogs) , one free-hub (cassette ate the free-hub so I changed to SRAM XD-driver). Bike started skipping so I replaced the cassette with a relatively new chain. Continued to skip so I changed the shifting cable inner and outer, still skipped. Bought a new Derailleur (upgraded from NX to GX) and still skipped. Changed out the derailleur hanger, still skipped. Measured the chain and figured it needed changing and then the skipping really got bad, bike is almost unusable in the lower gears because of more load. It's basically dangerous. It really feels like the free-hub is skipping, but after reading this it makes sense to buy a new chain-ring. It must be worn since the rest gets eaten up quickly. I will try this. Thanks for making the Video

[@dotlogzip634]

Try stopping peddaling when you shift if it is possible, if you shift under that much torque it will indeed eat up cassettes and chains
