Cassette wear

[cyfa2809]

how do you tell if your cassette is worn (too worn?)? i mean other than your gears slipping when its on the bike? is there a way of telling? maybe visually? is there a tool for it?

Your eye is that special tool...

 

[cyfa2809]

hmm ok, what to look for?

 

[Steve Kish]

Hooking of the sprocket teeth rather than a square-ish and symmetrical profile. If they start to look a bit like a shark's fin, they're on the way out!

 

[cyfa2809]

ah i thought as much, the little ones are starting that but i guess its cus theyre smaller! what about the big ones? the bigger ones are quite squareish, sort of like the bottom (big part) of an egg, is this ok?

 

[Steve Kish]

Big ones don't cause as much problem because of the greater wrap-around but TBH, as soon as wear is seen, I'd change chain and cassette together.

I've seen a worn chain fook a relatively new cassette in less than 200 miles.

 

[cyfa2809]

oh so its wise to change the chain often rather than everything not so often?

Yep.
