The BBrght Pressfit 46/24 bottom bracket is designed to be used on BBright frames such as the Cervelo R3, R5, S5. The bearings are compatible with a 24mm crankset spindle such as Shimano and FSA; but they can be used with an adapter for SRAM 22/24mm cranksets (select SRAM crank above).
There are 3 different bearing choices 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, Cycle cross, 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: If you have a BBrightTM frame and want to use a 30mm crankset, you will need our BB30PF which has the same dimensions as the BBright 46/30. The BB30PF can come with a middle tube (Di2) that is 52mm to be used with a BBright frame and 30mm electronic shifters. The tube ensures the cables do not rub on the crank spindle.
NOTE: For 22/24mm SRAM/Truvativ cranks you will need to select the SRAM option in the crank menu.
NOTE: For BMX cranks that use a 19mm spindle, road cranks with a 19mm spindle, and the FSA omega you will need our 19mm bushing kit which is sold separately.
