Have asked on rec.cycling .... but also trying here.
Following on from earlier post on Bottom Bracket. (and loads of help)
Removed the cranks and stripped out the Bottom Bracket, it's all now de-greased & cleaned ... before I re-assemble ... a Q?
The bracket consists of a spindle shaft, a fixed cup on chain side and adjustable cup on other. Each cup has a ball bearing cage with 9 ball bearings. There is also a plastic bellows between either end to keep things clean.
I read the Sheldon Brown web article on Bottom Brackets ... he advises consideration of discarding the cages, and instead putting in 11 loose bearings.
There are 2 thoughts ..
# I go ahead and do this ... cost is only for 22 1/4" balls (should be cheap enough)
# I put the existing 9 ball cages back in for now, and when the thing does wear out change it for a sealed cartridge BB ?
