Gear skipping/slipping

[JohnnyReggae]

I am using a 9 gear cassette and am having a problem with gear skipping/slipping on 1 gear specifically, in my case #8, 2nd smallest. No adjustment up or down seems to correct the problem, just mild skipping to massive skipping.

 

This only happens under load. My gear changes are great and don't have a problem with that. It happens to be the gear I like to do most of my riding in, but rather annoying if I need to quickly apply more power to go faster etc but can't as I need to first change either up or down to do that.

 

I can run on a larger chain ring and use other gears to get the same ratio that I like, but it still needs fixing. Any ideas of where / what I should be looking at, as I am scratching my head at the moment ?

How old is your cassette? I had this problem when I fitted a new chain with a fairly old cassette. Fitted new cassette, problem gone.

Year and half, 5500 km's ... Cassette is original, chain has done about 3500 km's.

Ditto to what Dustbin said - also check your front chain rings. HAd a similar issue and only once I've replaced "everything" possible, reset everything did someone mention the front rings and after they were replaced all was sorted!

i had the same problem on my wifes bike (10spd - shimano) but i think the principles remain the same;

 

1. is the chain the right way around

2. derailleur cage & drop-out was bent

Yoh, I would replace chain and cassette. If problem persists chances are the front rings are also slightly worn.

hhhhmmm shows how much I know, didn't know the chain had a specific direction. The chain was fitted by a tech at a bike shop after the chain that I fitted snapped after 200km's. (see point 1)

 

Looking at the derailleur it does seem "out of line", or rather twisted slightly. But then again I've been looking at this thing for too long to even see straight anymore

The bit where you said favourite gear gives the problem away - replace chain and cassette. Possibly rings too. Get your hanger straightened at the same time, then you've sorted out everything.

 

Or just stick to one wheel, they're far easier to fix.

I've been hoping that I wouldn't have to part with any schmee, but cycling is not as economical as unicycling I do like the simplicity of unicycles for a number of reasons, but they don't rate high on efficiency in covering any distance

yip says so on the user manual.

 

btw, i did not fit the original chain, assumed the bike shop knew what they where doing

I think chain direction only applies to 10 spd chains and not 9 spd.

I think chain direction only applies to 10 spd chains and not 9 spd.

 

Even then not to all 10sp chains
