    Vt-1 Bb

    Anyone know the BB size in my 2003 VT-1? I want to upgrade it as it's getting rough. I'm guessing 73 X 118 but I'm not sure if 68/73 matters with the BB in there or not. Thanks.

    Depends on your cranks, I use XTs and the BB size is 113/68.

    68 or 73 is the size of the BB shell and 113 or 118 is the lenght of the spindle.

    My .02

    I don't think I asked my question very well. I'm planning on keeping the Race Face cranks I have been using. I'm wondering if anyone knows the size for the BB without me taking the cranks off to measure the spindle. Or what is the size that comes on the bike from Giant? Thanks.

    Yes, I did. I couldn't find anything out. There is an '03 archive but no tech info. It would be nice to have the new one on hand and only have to pull everything apart once. Thanks for the help.

    Giant specs a 113 length on your VT. I own one and took mine out so I know its a 113.
