The BB30.D bottom bracket is designed to fit BB30 frames. This bottom bracket comes with an integrated alloy center tube and a 4.5mm spacer for the crank arms. Installed are Hawk RacingTM bearings that support 28.99mm crank sets such as DUB.
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.
Hawk RacingTM bottom brackets have been designed with the pro cyclist in mind. Replace your standard bottom bracket with a new generation bottom bracket that is 10% lighter than ceramic and takes up to 80% less energy than the next most efficient bottom bracket on the market.
Our bottom brackets use exclusively Folmer TechnologyTM bearings (patent pending) which have changed the perception of ceramic bearings by being ultra light weight, durable, and affordable. Our bearings help you make each performance your best and will last without needing frequent service intervals.
These specially designed bearings utilize a high-grade lubrication which is typically used in a slightly different form in the aerospace industry as well as a lighter seal than ceramic bearings. These features help get you to terminal velocity more quickly and easily.
Hawk Racing bearings have been used by Kendra Pro Cycling and Wonderful Pistachio Pro Cycling Teams here in the USA.
