Hi all im new to this forum but just thought id ask some of you guys if you have come across any problems with the x caliber 9 bottom bracket as i am having problems. Basically the left hand side thread of the bottom bracket keeps working itself loose and rubbing on my pedal arm thus causing the pedals to seize as it really gets tight. anybody else heard of this problem?? ignore the bash marks i had to loosen it somehow whilst out.

Thanks, as these dont seem very expensive i may be as well replacing it however no matter where i look i cannot find the model number or sizing for the bottom bracket. Do you have any idea where i can find this?

Hi, no offence taken i was using a hammer and screw driver as it locked up on me so needed a way to loosen it to get home however although it looks bashed i think internally it should still be fine. And i will be buying a correct tool for the job when i purchase the new one just not sure what model/ size to purchase

I've never actually seen it on a Bottom Bracket but have in many other places on bikes.. proper Torque should most likely hold it.. But I use Plumbers Tape on everything threaded on a bike now... works better than LockTite, holds, seals, works like Never Seize when you want to take it apart,.. costs under a buck.

Also, just a thought but even though YOU did the cup damage, I'd hit the shop you purchased from as they should have set it correctly in the 1st place and this never should have happened.. Bike is brand new and still under Warr...

then to top it off, there is something missing as the crank arm should have a spacer or something so just that can't happen as those look like Shimano cranks and the bearings are set by tension of the crank arm up against the bearing so it wouldn't be able to back out and hit the crank like that as the cranks arm should be tight to the bearing already..:skep:

Thanks!

well took my bike to my trusted mechanic last night and he sorted it for me (whilst i watched). Basically the bb was fooked barings were nackered so replaced it with a new nice green one :thumbsup: now feels super smooth, however he really wasnt sure why it was unwinding itself although he did mention that it could be the thread on the frame but im gunna see how the new one goes and if this comes loose i need the frame thread sorting out. Thanks for all you help :D
