Hi all, I went out for a ride last night on my Onza Zoot. Fairly near the end of the ride the bottom bracket became very stiff on every rotation at the same point. Me and my mate believed this to be a bent axle however i have removed the bb this morning and replaced it again. I did the cups up until it was tight and then removed half a turn of the thread on the drive side. This seems to have solved it. I was wondering whether this is a common problem and what the solution is or is it safe to ride as it is? any help appreciated.
