PF30 Outboard Angular Contact BB for 24/22mm Cranks (SRAM) - Red

BB Installation

Two machined aluminum cups thread together keeping the bottom bracket 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 22mm / 24mm spindle diameter cranks (SRAM / Truvativ GXP) in PF30 (46mm ID BB shell) frames without the need for any adapters.

Enduro Bearings

Enduro ABEC-3 Bearings

Grade 10 Chromium Steel Balls:

High precision balls are within 10/1,000,000″ round, twice as round as the industry standard, at it’s 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


Enduro Angular Contact Bearings

Enduro Angular Contact Sealed Bearings

Enduro Angular Contact bearings are specifically designed for hubs and bottom brackets. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact 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.

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.

We back them up with a 1 year warranty.*

Note: if your BB shell is slightly oversize, two BB wrenches may be required to fully tighten cups in frame.
