Are you sure that the original bottom bracket would cause the chainrings to hit the chainstay? If so they yes, you may need to go wider.
Here’s what I would do: Install the crank on your XO-2. Measure the chain line in the front, following Sheldon’s directions. Let’s see what that number is. Then tell us what rear hub and cassette you are using. If you focus on hitting the correct chain line, presumably 47.5mm then you shouldn’t hit the seat stay with the chainrings. (I personally wouldn’t squeeze the frame to fit the hub but others would certainly do that.) -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
