All sorry for this really dumb question. I have a 2021 cube reaction hybrid performance bike. The rims say 32h on them. I have Sad Sam tyres on them but I want something more suitable for roads. But I am totally confused as what I should be looking for, as the paperwork refers to 700c and 29 inch tyres, and I don’t know what relevance the 32h has. can anybody tell me what I should be ordering? jimbo

thanks. My sense is that it is just a set up issue - can’t figure out what I’ve done wrong is all.

Hi all, Recently bought a new Cube Reaction Hybrid Performance 500. This is my first electric bike. I’ve done 120 miles on it in the three weeks I’ve had it and find it fantastic. I’ve not owned a bike since I was a kid (30 years ago), And perhaps stupidly had the bike delivered for me to build myself. My question is this: in the highest gear (8/9) the front chain regularly jumps off and gets rammed between the chainring and the frame. What am I doing wrong? jimbo.
