Chain skipping on jockey wheel

Shortened the chain two links and screwed the b screw most of the way out which moved the top jockey wheel much closer to the chain, improving shifting and eliminating skipping (although chain and The top jockey wheel (called the guide pulley) is designed to have lateral play, this allows good meshing with the sprockets even if indexing is slightly out. A jumping chain is more likely due to a stiff link, a breaking link (check thoroughly) or the indexing being out so the chain is trying to grab the next sprocket. I see that 2 chain rollers come from beneath improperly engaged, and those are the ones that cause the skipping. Maybe the upper jockey wheel rests too close to the cogs, or moves up and down too much (possibly hitting the cogs), and somehow is causing a few rollers to engage earlier than they should, before the ones in front of them had time to engage properly.

Also easy to check that the jockey wheels are moving freely. Take the chain off the small ring to take all the tension off. Pull it away from the jockey wheels and see if they spin. If a jockey is sticky it delays the chain being taken up as you shift rings, and it would just flop around for a second, and could well do what you show in the It could be a few things: > Your chain has a tight link (or a few), meaning it doesn’t bend when it is supposed to and leaves a gap between the teeth and the chain. This causes some skipping. Check your chain for stiff sections and lube it and mov None of the above! Hanger is fine, I check that almost every ride, chain/cassette only a month old, I just changed the derailleur cable for a teflon lined one that is great, I just did a full hub service on my Mavic Crossmax with new bushings and bearings from the hub doctor, but that was not the issue anyway, (I was talking about the jockey wheel), and the cage is all good except for the wear The fact that the skipping occurs less on the chainring is also a consequence of there being less leverage on the large chainring resulting in less chain tension. The jockey wheel will also droop more when the chain is on the smaller rings, resulting in less chain wrap.

If the chain is skipping over teeth but staying on the correct cog, it may be a worn chain, but it's possible the chain is too long and the upper jockey wheel is contacting the smaller cogs. With the chain removed, look closely at the hanger. My chains jumping off the bottom jockey wheel on my giant defy. Skip trial 1 month free. Find out why Close. Help.

The jockey or pulley wheels on your bike do the job of both moving the chain across the cassette as well as keeping the chain tensioned. In the process, they turn thousands of times and get pretty I recently took my bike apart to remove some rust and re-paint it, and ever since cleaning everything and putting it back together the chain sort of skips as soon as you put a bit of force into it. It's not the main cogs as I've put as much force as I could with the bike still and the chain

18 Nov 2016 The chain gap is the distance between the largest sprocket and the upper jockey wheel, and it should be about 22 mm. SRAM provide a gauge, 

It will also provide a bit more engagement with the jockey wheels, which may improve the chain jumping issue. 6 Nov 2017 The rear derailleur is made of up pulley wheels, springs and causing the chain to jump up or down the gear cluster as the wheels and springs  18 Aug 2017 The chain should run smoothly without any clicking, or skipping noises. If the chain isn't coming directly off the upper jockey wheel and going 

The term jockey wheel predominantly refers to a wheel-based mechanical system used for steering or guidance. It is either. a guide wheel - usually operating as a pair - which is used to move, retain, locate and (usually) add tension to a chain, rope or cable which is then fed into the groove of another wheel,

If you have just replaced your chain and not your chainrings, and your chain skips under load/pressure (like pedaling up a hill), replace your chainrings or take your bike to your local bike shop.
