There are a large number of BB standards being used across the mountain, road, and gravel spectrum of bikes. e*thirteen makes BB's for all of the most common standards but there are some standards which we do not produce a compatible components for.
Bottom bracket standards we support:
- BSA Threaded: The most common threaded standard found across all brands. e*thirteen makes threaded BB's for 68mm (gravel), 68/73mm (mountain), and 83mm (Mountain DH).
- BB 86.5/92/107: The most common pressfit standard. e*thirteen's BB92 bottom brackets will fit frames with these shell widths. 86.5 (road), 92(mtn), and 107(mtn DH).
- PF30 and BB30: PF30 and BB30 are less common press fit standards and we make BB for both these standards.
- T47 Threaded: T47 is a newer standard and not all that common. We do make a BB for the T47 Standard.
Bottom bracket standards we do not support:
- BB90/BB95 (Trek)
