jumping on 6 and 7th sprockets
Hi, had my bike in for a service and had a new chain fitted, Took it out tonight for first spin and when put the power down when in thr 6th and 7th sprockets (10 speed campy veloce) it seems to kind of jump a link and jump or just jump a bit. Happens when eithe in big or small chainrings. When jsut spining the gear it is ok, just when put power down and sprint it jumps. What is the problem so i can go in prepared when take bike back in tomorrow

Who knows, could just be crappy indexing. Cruddy cables, worn cassette (worn enough to not mesh with new chain).
Just learn to DIY, bikes don't need servicing, they need regular routine maintenance.I don't do smileys.

A worn cassette would work well with a worn chain. You only realise the cassette's worn when you fit a new chain and it jumps under power.
1500 miles isn't a lot, but not unheard of. More likely if it's all winter miles / no guards.
I'd guess a new cassette would sort it.0 -
yip, new cassette it was. Decently though the shop replaced it free of charge with cost price replacement so can't complain too much0
