BB30 Outboard Ceramic Hybrid BB for 24mm Cranks (Shimano) - Red

BB86/92 Installation

Our BB30 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 24.00mm spindle diameter cranks (Shimano, Etc.) in BB30 (42mm ID BB shell) frames without the need for any adapters.

Note: FSA MegaExo spindles can be between 24.00mm and 24.07mm in diameter. If your FSA spindle is 24.07mm, this BB will not work! Please call us at 800-361-8422 or email us at info@wheelsmfg.com to purchase our FSA 24.07x37 ceramic hybrid bearings separately.

Enduro Ceramic Hybrid Bearings

Enduro Ceramic Hybrid bearings have Grade 5 ceramic balls with ABEC 5 chromium steel races.  Bearings are made from pure Silicon Nitride material with extreme high density from uniform compaction, the micro-structural development of this material during manufacturing is second to none.

Grade 5 Si3n4 Ceramic Balls:

  • High precision balls are within 5/1,000,000″ round, 60% lighter weight, and 7 times harder than steel.

52100 High Carbon Chromium Alloy Races:

  • Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-5 precision and noiseless movement.

The bearing seals are dual lip, groove type seals rather than standard 2RS types that other manufacturers use; one lip to keep the dirt out and the other to keep the 90% grease fill inside. Bearings are filled both sides with Rheolube grease for the best protection and long lasting set up. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.

We back them up with a 1 year warranty.*
