The BB.ENG.3086 bottom bracket is designed to be used with BB30* cranks that have a longer spindle than standard BB30 crank sets. This is also known as a BSA 30 or BB386 bottom bracket. It comes with a 3086 installation tool to make your life easier!
There are 3 different bearing options to best meet your needs:
- Standard Bearings: Use for road bikes in dry/no salt environments.
- Full Stainless Steel Bearings: Use for extreme distance riding (>200miles/week), BMX, MTN, and other varying conditions.
- Full Stainless Steel Bearings with CX Seals: The CX seal is for riding conditions where water, dust, and debris can get into the bearing and degrade it prematurely. Use for MTN, BMX, Cycle Cross, or other wet and dirty conditions. NOTE: This is not for timed road biking as the extra seal slightly increases wattage.
NOTE: A standard BB30 crank set WILL NOT work with an English threaded frame due to the spindle being too short. You need a 86.5mm spindle length such as the Rotor 3D+ or FSA 386 EVO.
