    PF4130 Road and MTB Bottom Bracket

    The PF4130 bottom bracket is Press Fit into 41mm diameter shells that are 86.5mm wide and mate most cranks with a 30mm spindle to that standard. If you have a BB86 frame and want to install a 386EVO crank or Rotor 30mm crank, this is the kit you need.

    CeramicSpeed bearings are installed in cups. The Standard Bearing has ceramic CS balls and hardened-steel races. The Coated Bearing has the same balls running on hardened-steel races with a 3-micron thick metallic coating making the races harder and smoother, increasing service life and reducing friction. 

    In the Box

    • 2 0.5mm spacers.

    • 2 dust covers.

    • O-ring.

    • Sticker sheet.

    Technical Data

    Enjoying the benefit of a massive, strong, and light 30mm crank spindle in your BB86 frame is possible with this kit. Press in the cups, set up the wave washer, add spacers if necessary, and torque down.

    CeramicSpeed’s bottom bracket is also stiff and light, but it’s biggest benefits are from drag reduction. Standard Bearings with stock grease typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to conventional bottom brackets. The bearings last at least three times longer than other bearings.

    Performance can be tuned by grease choice. All Round comes with, but you can change it to Race Day Grease for less drag or to Long Life for greater durability.

    Installation of PF4130 Road and MTB Bottom Bracket

    If you don't have any experience installing bottom brackets and bearings, we recommend that you have your local bike shop fit your new bearings.
