These are the best deal out there, considering price and quality. Made in Japan by Tange, for IRD. Shimano bottom brackets cost less and are fine, but these seem better. The finish, the materials... and we trust Tange of Japan.

If you're using a Silver crank with a "MTN" front derailler, get a 113. If you're using a road front derailler: 110mm. If you're squeezing a big tire onto a Clem and want a little more chain clearance in the low gears, get a 118; It'll work perfectly.

Bottom bracket  for 68mm shells. JIS taper, BSA threading.
