This bottom bracket set is designed to fit bicycles with a 68mm wide American-style bottom bracket shell, a common size for BMX and cruiser bikes.
Spindle Type: 22mm
Compatible with 3-piece cranksets that use a 22mm spindle, which provides extra strength and durability for more demanding riding styles like BMX or mountain biking.
Cup Type: Press Fit 51mm
The press-fit cup system has a 51mm diameter, ensuring a tight and secure fit inside the bottom bracket shell. This type of installation is simple and effective, eliminating the need for threads and minimizing creaks or loosening over time.
Interface: American

Bearings: Sealed 41mm
The kit comes equipped with sealed 41mm bearings, providing smooth operation and protection from dirt, dust, and moisture. The sealed design helps ensure longer-lasting performance by keeping contaminants out, reducing the need for frequent maintenance.
Material: Alloy
