Shimano R9100 ITL Bottom Bracket Adapter Set 70mm - Black

The Shimano Dura Ace 9100 bottom bracket is known for its reliability. The bearings are designed to last a long time and run smoothly. The bottom bracket is suitable for Shimano Hollowtech II compatible racing cranksets. There are two types; BSA and ITA. This is the type of wire. Most bicycles have BSA thread. BSA is 68mm and the bracket says 1.37 x 24. ITA is 70mm and the outside says 36 x 24. Another type of step bearing is Press fit. There are no wires on this, they are pressed into the frame.

- This clearly shows the core of Shimano's philosophy of system-developed components.
- The result is called SYSTEM SUPREMACY - the superiority of the system over the sum of its individual parts.

The Shimano Dura Ace bearing shells with Italian thread are suitable for the Dura Ace FC-R9100 Hollowtech II crankset.
