Hi guys. I'm new to the forum so hello from Devon.
I have a 2021 Cube Reaction with a Bosch CX engine and a Haibike Hardnine 6 with a Yamaha engine.
On my Cube I recently noticed that while in gears 10 and 12 the chain started jumping/slipping. I did all the usual stuff like setting the gears up again which made no difference so took the wheel off after noticing slight play in the rear cassette. It has a Sram NX Eagle PG1230 cassette system and the first 4 cogs are fixed while the others go on individually. I took the cassette off and took it apart to give it a good clean. I then put it back on and tightened it up properly eliminating the play. On the stand the bike goes through all the gears smoothly and sounds good but when I take it out on the road, it's fine for the first 8 gears but now 9-12 are jumping/slipping. I scrutinized all the cogs of the cassette while it was off and they all seem good. I even took the bike to Halfords for their free health check and they also reckoned the cassette looks fine and the chain is also good. I'm now scratching my head trying to work out what's going on as I've done all the usual things. Does anyone more techy clued up then me have any ideas? Thanks in advance.
