My rear cassette might be worn but I can't fucking tell to be honest. It looks fucking fine, but the damn chain skips forward (not trying to go to other gears aka. the shifting is fine and I've done indexing on it many times) so what could the issue be if it isn't the cassette? Too short of a chain? I measured it around the fucking biggest gears so it should be perfect and added 3 rivets (for an 8 speed).
It only starts skipping on gears 4-7 on the rear derailleur, but works fine on 1-3 (biggest cogs) but I honestly pedal too hard for these. I often pedal uphill and put my full weight (100 kg) on the damn thing and the chain did skip and break twice (old chain) before I bought a new one. I'm tired of working on this one bike and a new cassette is like 20€ and they are ALL SOLD OUT EVERYWHERE. So I can't even get a new one right now.
I could buy a used shitty bike for 20€ and get RNG lucky with a decent cassette but fuck me. I got a cassette of an 8-speed bike that I'm repairing but honestly I don't want to take that apart to fix this one anymore, but I do have an old bike from the 90's with a cassette that is the same speed. Could that work? How do you clean old cassettes and is it a bad idea to use them from old bikes?
