I found this very helpful chart of Tange BB's, and Shimano's UN54 are about the same proportions. This is invaluable if you want to go changing BB's. The 111mm Tange is labelled as a 110 BTW.
Look carefully at the charts ,as driveside/non driveside proportions are surprising, they don't really follow any what we may call a logical progression. http://farm5.static.flickr.com/4085/5029565072_d7ebfb0b4d.jpg http://blog.harriscyclery.com/relative-chainline-bottom-brackets/ You can use even a 118mm BB with a XD2 and get a decent 47-47.5mm chainline and a wider Q. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
