Hi! I tried to mount a Sugino XD2 crank from RBW on a 107mm VO bottom bracket and couldn't make it work. Mounting the crank onto the spindle, before I had slid it on far enough to get the appropriate torque on the crank bolt, the inner portion of the crank arm interfered with the bottom bracket itself! At first when I was having trouble turning the cranks I thought... hmmm, did I ruin a bearing or something? But no, it was just that the crank arm was literally jammed up against the bottom bracket itself. Just plain weird.
Anyway, I suspect both the VO bottom bracket and the XD2 crank I have are perfectly fine normal examples of their kind. And I suspect the VO BB is a fine product in general, as is the XD2 crank. They just didn't work together for me. The only other bottom bracket I had lying around was a 113mm Truvativ, which turns just fine for now. When it shows age, I may replace it with a larger VO. I wasn't really very close to the required torque on the crank when it came in contact with the bottom bracket. It isn't obvious that a 110mm VO bottom bracket would work. I suspect a 113mm would, though. Perhaps I should just get the 107mm from RBW. This would give me the intended chainline. However, I'm going to eyeball carefully my current set up. I haven't concerned myself with Q-factor up to this point; longer spindles on a bottom bracket don't bother me as long as the chainline is reasonable for how I ride. I need to give that more thought. I may even go with a 118mm BB if the chainline is okay. At that point, the crank arms might just slip right past the two-legged Pletscher kickstand when its deployed. That basically turns the kickstand into a work stand. (That and a couple of ceiling-mounted $3 bicycle hooks were the only stand I used to the build the bike up with in the first place.) Anyway... just in case anybody else tries the 107mm VO BB with an XD2 crank. I wouldn't expect it to work right out of the box.
