This bottom bracket is an internal, bearings only system so it fits completely within the frame shell. The bearings are compatible with a 24mm crankset spindle such as Shimano and FSA; and they can be used with an adapter for SRAM 22/24mm cranksets.

Details

The BB90 Madone was designed to be used in high-end Trek bicycle frames (2008 and newer) and some Gary Fisher bicycles. This bottom bracket is an internal, bearings only system so it fits completely within the frame shell. The bearings are compatible with a 24mm crankset spindle such as Shimano and FSA; and they can be used with an adapter for SRAM 22/24mm cranksets.

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: For 22/24mm SRAM/Truvativ cranks you will need our SRAM adapter kit that is sold separately.

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.

This product ships with (2) bearings, (1) wave washer, and a 6.5cc sachet of Crystal Grease for a smooth installation. Order more grease, if needed, via our website.

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.

Thanks to our customer’s ideas and our authorized dealers, we now offer the BB90 Madone so you can upgrade your bicycle to a Hawk Racing bottom bracket and reduce friction while gaining speed.
