Description

If you have a 2008 or newer Trek bicycle frame then the BB90 Madone is the bottom bracket for you. 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 can be used with an adapter for SRAM 22/24mm cranksets (select SRAM crank above).

Our BB90’s, just like all our bottom brackets, where made using our famous Folmer Technology. This is how you know you are getting a bearing that is smoother, lighter, and will last longer than most other brands of bottom bracket.

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 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.

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.
