New chain slipping

TheDutch

Hi all, I have a beginner / tech crossover problem; I suspect the answer to which is money and time.

I was lucky enough to snap the chain on my aging bike a couple of days ago, and have today installed a new Shimano HG50 chain. Having done so the chain constantly slips when a reasonable amount of force is applied, though light pedalling is OK. The cassette is a Shimano HG-C 8 speed type ah, and it slips to varying degrees on every sprocket. I cannot say for sure how long it's been on for as I didn't put it on.

My suspicion is that the sprockets are worn out and should be replaced with the new chain, but it does not look (to my exceedingly untrained eye) to be massively worn out. Are there any other reasons this may be happening? Is the new chain likely to 'bed in' whatsoever?

Here are a couple of terrible camera phone pics of the suspect:




So there you go; new cassette or something else?

Many thanks,

Dutch

that looks very worn out to me. The round bits between the teeth are elongated quite dramatically.It's always best to replace the cassette + chain + chainrings at the same time.

holy 5hit, every single sprocket looks destroyed.

Casettes teeth always look elongated even when new, but a new chain slipping on an old cassette is a classic situation. You need a new cassette and possibly new chainrings.

erm, I've never seen a new one look that elongated though. That's fair shagged, it be!
