Did the Shimano UN-91 XTR M900 bottom brackets only come in 2 axle lengths 107 and 113mm? or did they make others lengths
was looking though my bottom brackets and have a 115mm UN-91 in 68mm shell with DH stamped on the axle... would this be for full suspension frames?.. down hill bikes in the early 90s
