Our PF30 Outboard bottom bracket will give you all of the same benefits as our well-loved Outboard style BBs. The two machined aluminum cups thread together ensuring the bottom bracket remains stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.

Specifically designed for installing 24mm spindle diameter cranks (Shimano, FSA, Etc.) in PF30 & Specialized Carbon OSBB frames without the need for any adapters.

Bearing Info

Enduro ZERØ Ceramic Bearings

The ZERØ ceramic bearings have ceramic balls and steel races.  The balls are Grade 3, Silicon Nitride (Si3n4).  These are the roundest balls you can buy without a military license.  The races are treated with a black oxide coating, which helps prevent rusting in the bearing. The races are then reground to a mirror finish after this treatment. Finally, they are cryogenically treated for strength before assembly. We also use Silicone VV seals, which is the lightest drag seal available on the market.

Si3N4 balls with 52100 High carbon Chromium Alloy Races with Cryogenic Treatment:
 Cryogenic treatment takes the races down to minus three hundred degree Fahrenheit to normalize the crystalline structure of the material so the races will resist the hardness of the ceramic balls and get the maximum wear potential

  • ABEC-5 rated Ceramic Hybrid bearing with Grade 3 balls
  • Cryogenically treated races will outlast any other bearing on the market
  • Dual lip, groove type seals keep dirt out and 90% fill rate grease in
  • Rheolube special synthetic grease is long lasting and protects against contamination
  • USA made balls are micro-coated with long lasting protection from friction

We back them up with a 1 year warranty.*
