Key features
- Threaded fitting — no press tools, no creaking.
- Covers both 68mm road and 73mm MTB shells with the spacers supplied.
- Sealed bearings that shrug off wet-weather riding.
- Works with any 24mm Hollowtech II crank.
Creaking from the cranks is usually the bottom bracket. We can check yours while you wait.
