Wheels Manufacturing’s original BB30 bottom bracket is a significant upgrade to any OEM BB30 bottom bracket. Two machined aluminum cups offer increased durability and bearing life, while keeping a simple press together method for installation and maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.
Features:
- Converts BB30 shells (42mm ID- 68mm road/73mm mountain) to accept most 24mm or 24/22mm spindle cranks
- For 24/22mm (SRAM/Truvativ) for installation into BB30 frames without the need for adapters
- Includes anodized aluminum cups with Enduro sealed bearings
- Base: Enduro ABEC 3 sealed bearings
