Bottom bracket woes,

ilovegrace

I have a felt Z5 with a press fit bb , never again !!
Lots of problems with it , eventually my lbs fitted a wheels manufacturing set up , all ok for 8 months then creak rattle and roll £105 to have it fitted , tried some cheaper bearing £50 , lasted 4 months , just had better bearings fitted £65 noticed yesterday a little play , went back to lbs, they had a look , and told me that the LHS of the axle was worn and was causing the play. Now need a new chain set .
it is a 105 11 speed . Does this happen ?? why does it happen thought axles were tougher than this ,.
Wish I could go back to running , no where near the expense of cycling
regards

Hi
What can be done about it?
Just changed a 105 from my other bike onto the felt and all is tight as a drum.
But I wonder for how long ?
I can not keep changing chain sets ,
I have been watching Hambini on youtube, makes me think the bearing lines a re out of parallel causing the wear on the axle .
Thought the wheels manufacturing outboard bb would help , not so sure now.

It's not cycling that's the problem.it the bike you picked. You may not have known at the time but many modern bikes with press for bbs are a bit rubbish.

Have these bb cups been loctited in place.

I agree with thecycleclinic. The best solution I've found (other than opting for a frame with threaded BB shell) is using the Hope PF BBs will the cups that screw together with a collar. They aren't cheap but are top quality and work really well.
