The BB.ENG.30.D bottom bracket is designed to be used with DUB cranks and English Threaded frames.
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.
