I have a Giant XTC SX with a Truvativ Isis crank
Just giving it a clean and I can feel play in the bottom bracket
What size do I need and what are my options for a replacement?
on the BB its says - single bearing 68mm shell o ring, 73mm shell no o ring
completely clueless otherwise
cheers
o rings are there
so do I measure from o ring to o ring?
where would the axle size be written?
can't see anything
Once out its on the body or just measure it from end to end I guess it would be 113 or 118 mm.
Why not change to HT2 ?
is there much advantage to hollowtech 2?
so I need to take it to my LBS to take out the BB, then order a new one and take it back for them to fit it
