I serviced the bottom bracket on my Daughter's hybrid bike last night. It is a (Halfords) Apollo Code. I bought it about 7 years ago at a discount. I think it was about £80 (reduced from around £150). The bottom bracket on this bike has always been a bit dodgy for some reason. Always getting loose and needs re-tightening. The problem last night was that the spindle had got loose which had caused the non-drive crank to loosen up. I think the crank is basically knackered (tighten it as much as you like and it gets loose again). It is an old style, square taper BB with cage bearings. I basically took the whole thing apart, cleaned it up, replaced the bearings, packed it with grease, and put the BB back together again. I found a similar (old) crank to the one which is knackered (described above) and it seems to work fine. I don't want to spend any money on it. I mickled the chain and put it all back together again. My daughter used it to get to work this morning. She says it is working beautifully. Onwards and upwards ... Edit: Moderator, sorry, I forgot about the Fettled thread. I should have posted it there in the first place instead of creating my own.
