Just fitted a new chain and tried servicing my rear mech etc but now ive just tried pedaling and when I pedal hard or with any force the chain starts skipping! The rear mech seems set up right but I cant figure out why its skipping under force?

Any ideas?

Thanks

Simon

Chain has worn the cassette, time for a new one 😥

edit: or put the old chain back on

Happens all the time i'm afraid.

You can splash out on a new cassette and that will usually cure it !

Changed my chain a month ago despite it still being within limits according to my Park chain gauge. The cassette was changed when i got that chain.

Lots of skipping with the new chain though it is settling down now.

Seems just to be a degree of incompatability, though i can't figure out why that should be the case if the rings are not badly worn.
