prematurely worn chainring

[MattHB]

elo folks.

during cleaning this afternoon I noticed quite a bit of wear on my large chainring. Im quite surprised as Ive only done 620 miles on the bike!







Is this rate of wear normal? Or am I putting too much pressure on the pedals when changing gear? Or is it just a cheap item which isnt the best quality?

cheers in advance

Are you thinking all the cogs should look the same else there must be wear? See new one below, I am not sure it looks that different to yours.

Oooo that's interesting. Yeah I was thinking they should be uniform.

Why are they not?

The big ring has chipped and filed teeth to enable a smoother change - your chainring won't have worn very much at all.

It's the same with the sprockets on your cassette - there's all sorts of weird things going on to encourage the chain to go where it's told, when it would be quite happy to stay put...

Ahhhh that all makes sense phew, thanks all
