I'm posting with another bottom bracket question (this time it's my bike).
I was cleaning my drivetrain last week and noticed that my bottom bracket has some play in it (when you hold the cranks they can be wobbled by 2-3mm (at the crank ends). Rotating the crank when free of chain also sounds a little grindy.
I suspect the cartridge bearings in the bottom bracket are coming to the end of their life. They will have done 6000-7000 miles with my heavy (190lb) bulk on them so I guess it is to be expected, it is funny that this has never happened to me before, all my other bikes have been stolen before I've got to this stage.
My question is what do I do now?
Can I replace the bearings? I suspect not, in which case what bottom bracket do I get to replace this one?
I'm not sure exactly what the bottom bracket model is but the crankset is truvativ elita (circa 2003-2004ish) the bike is a cannondale R600 double from around that time although differs from the spec in their archive where they have shimano BB and crankset. Looking at the truvativ website the gigapipe ones look kind of similar to what I've got when viewed from the end (I've never removed the unit from the shell – never had cause to until now). I think it is probably worth keeping the crankset, it seems in reasonable shape, chainwheels are probably a bit worn but could be replaced separately later if necessary.
Do I go for a truvativ one again and if so do you think that the gigapipe ones sound right for the elita set?
