Morning all!
I have an issue with my bottom bracket. It is slightly loose as if it has not been tightened properly. It is a sealed bearing unit (RPM ISIS drive).
The slight looseness is causing a knocking that is emphasised all the way to the pedals, so making a lot of noise and being really annoying.
Does anyone have any tips on how to stop this? I know nothing about the workings of these or how to dismantle them etc - or even if this is possible? Should I just replace it???
If so any recommendations would be useful - for an AM rig, internal ISIS, max £40 ish.
Many thanks!
Sounds like the bearings are on their way out: if its a sealed unit you will have no option but to replace it. Despite the rantings on the other thread, I heard some good things about the superstar components isis bottom bracket, otherwise just have a trawl through the reviews on chain reaction ^^.
