Our carbon fiber bottom bracket shell is the part of a bicycle's frame where the bottom bracket and crankset is mounted. This bottom bracket is 46mm ID and is compatible with PF30 (aka Press-fit 30) cranksets. We offer pre-sized lengths for road bikes (68mm), mountain bikes (73mm), fat bikes (100mm), and bikes using the FSA 386EVO standard (86.5mm). We also offer a full 37.4” tube that can be trimmed to any length you desire.
Quick Facts About This 46mm Bottom Bracket
- PF30 (aka Press-fit 30) Compatible
- Unidirectional Matte Finish
- 46mm ID x 52mm OD
- Glass layer on the inside to minimize corrosion when used with aluminum bearing components

- 0° Fibers maximize bending stiffness. Consider bending the tube over your knee.
- 45° Fibers maximize torsional stiffness. Typically plied together in an opposing manner, i.e. ±45°. Consider twisting the tube like a vehicle's driveshaft.
- 90° Fibers maximize crushing stiffness and generally assist in overall tube strength. Consider laying the tube on the ground and stepping on it.
