Bought new external BB about 4 months ago as the first one developed alot of play and tore itself apart when I took the cranks off the service them. Same thing just happened again. The plastic sealed bearing sort of fuses to the crank axle and comes out of the bb cup when I try to take off the cranks.
A tiagra bb should last longer than 4 months, surely? what might I be doing wrong? Would buying 105 or ultegra make much difference?
Last time I asked about this you were all very funny, this time any advice appreciated.
Thanks
