90's peugeot gear problem

[firefly69]

Hi guys, just rebuilt my old peugeot, but having a problem with the chain slipping/jumping when in 1st, 2nd & 3rd...its climbing over the sproket, its ok in all the other gears....i did fit a new 8 speed chain...it is an 8 speed sprocket on the bike...any ideas?
could it be the chain?
thanks guys

Sounds like a worn sprocket. Typically it's the smallest cogs which wear most. Sounds like you need a new cassette.

Welll, erm, what hamster said, really. If some gears get used more often than others, individual sprockets will wear out and give chain skip even if the rest of the block is basically OK. As such, replacement of the whole lot is annoying in terms of your wallet, but necessary.

Hi again guys, i tried a new sprocket on the bike but it's still jumping...could it be the hub itself...is there anyway of getting it apart?
cheers
