The bearings in my Race Face Signature XS ISIS bottom bracket are worn. Race Face says they are "serviceable and replaceable". And their tech line gave me the part number for the tool which includes cups and bearings for two rebuilds -#BBISSVLT. However, when I attempted to order this kit at the LBS, the proprietor vehemently discouraged me. He told me his own staff of mechanics never, ever rebuild cartrige bearing BB's because it's just not worth the intense effort. He suggested my best course of action would be to simply buy a new BB - which he was all too willing to sell me.
So my question is; has anyone out there ever replaced the bearings in an ISIS bottom bracket? Is it really that hard? (or is this guy just taking the path of least resistance to my hard earned doe?)
I really love these particular BB's. If you're familiar with them you know they make that last little chain line adjustment a snap. Race Face no longer features them on their web site, so the ability to rebuild them might be crucial for me.
Thanks in advance. All the best. DanO
