I just picked up a 2004 Dakota XC frame and have been trying to figure out how to spec it out. I can get a good price on the older style XT crank that uses the ocatlink BB, I know the shell is 63mm but I'm unsure of the spindle length. On the Jamis website it says 113 but that is for the stock Truvative crank, I've heard that if you have a 113 spindle length you should go with the 121 octalink Shimano BB but I wanted to confirm that before buying. Has anyone out there upgraded to an XT or LX crank/BB and can tell me the correct spindle length to buy?
