The Wheels Mfg original PF30 bottom bracket is a significant upgrade to any OEM PF30 bottom bracket. Two machined aluminum cups offer increased durability and bearing life, while keeping a simple press together method for installation and maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.

- Bearings: Enduro Ceramic Hybrid - Color: Black
- Bottom Bracket/Frame Interface: PF30, BB386EVO, Specialized Carbon OSBB, BBRight" Press Fit
- Bottom Bracket Shell Width (mm): 61mm to 86.5mm
- Bottom Bracket Shell I.D.: 46mm - Crank Spindle Type: BB30
- Crank Spindle Diameter: 30mm - Weight: 104g

This bottom bracket is a direct replacement for SRAM, FSA, and other PressFit 30 bottom brackets and a great upgrade because it offers all of this:

  • Made in the USA
  • Features Enduro 6806 OS (30mm ID) ABEC 3 sealed bearings
  • 12% increase in static load rating compared to standard 6806 bearings
  • Dual silicone seals keep the contamination out for longer life
  • Adaptable BB to fit PressFit 30 specific frames (46mm ID) with shell widths from 61mm to 86.5mm
  • Will accept current 30mm spindle cranksets, and 24mm and 24/22mm cranksets using Wheels Mfg. adapter shims
You get radial deep-groove bearings that have 5/32-inch Grade 20 balls, the largest in the industry, resulting in a 12% increase in static load compared to standard 6806 bearings. Dirt and outside elements are kept out by no less than two double-lip seal systems. 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.
 
Also, the bearings are filled on both sides with Mobil HP 222 synthetic grease for the best protection and long-lasting setup. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration, too!

This Wheels Manufacturing PressFit 30 Bottom Brackets has Ceramic Bearings. These bottom brackets are available with the following 3 bearing types.

Sealed Bearings - Most Economical1) Enduro ABEC-3 Sealed Bearings - Most Economical

Grade 10 Chromium Steel Balls: High precision balls are within 10/1,000,000-inch round, twice as round as the industry standard, at its highest level.

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-3 precision and noiseless movement.

Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance

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 on both sides with Mobil HP 222 synthetic grease for the best protection and long-lasting setup. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.

Angular Contact Bearings - Best Ride Quality/Durability2) Enduro Angular Contact Sealed Bearings - Best Ride Quality / Durability

Enduro Angular Contact (A/C) cartridge bearings are specifically designed for bottom brackets (and hubs). In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear.

Grade 5 Chromium Steel Balls: High precision balls are within 5/1,000,000? round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade.

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.

Graphite/Nylon Ball Retainers: Nylon with graphite retainers are virtually frictionless while providing constant lubrication.

Because of the internal ball path design, all of the balls are engaged 100% of the time lending even and maximum support through the entire pedal stroke. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction.

"LLB" dual-lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.

Wheels Manufacturing backs them up with a 1 year warranty.

Ceramic Bearings - Fastest3) Enduro Ceramic Hybrid Sealed Bearings - Fastest

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.
