  • BB386 Bottom Bracket for Shimano Hollowtech II Crankset
    Designed for 386 Evo bottom bracket shells when using a Shimano Hollowtech II crankset.

    The TorqTite bottom bracket line is designed to replace any press fit type on the market. This means no more glue, paste or tape to try and keep things quiet. This unique and patent pending system uses a double threaded internal sleeve to tighten the right and left cups with two spanner wrenches and torque your bottom bracket tight on installation. No more movement or internal fretting of your bottom bracket against your carbon fiber or aluminum frame, just a tightened mechanical system eliminating annoying and unwanted noises. Noises and internal friction that can also sap energy and wattage output. TorqTite guarantees perfect parallel alignment between the bearings even if the frame is not perfectly straight, eliminating lost energy.

    Available with the best Enduro XD-15 ceramic bearings, or with 440C stainless bearings, the TorqTite system is the ultimate bottom bracket system to guarantee the best results with the highest wattage output and no unwanted friction.

    XD-15 Pro
    XD-15 ceramic bearings use a different material than any other bearing on the market and is exclusive only to Enduro bearings. XD-15 is a very special nitrogen infused steel material that will not rust or corrode. Even running in salt water or any caustic nutrition drink you can spill, it will not be degraded or affected. Even dirt or sand inside will not wear it out; this will simply polish the races smoother. The process to produce this steel involves re-melting a very high grade of martensitic stainless steel from the end of an electrode. This occurs in a highly-controlled re-melt chamber while introducing nitrogen gas, producing a homogenous steel, free from course carbides and giving ultimate fatigue resistance. A super tough and strong steel perfectly mated with Grade 3 Silicon Nitride ceramic balls, XD-15 bearings start out great and get even better with riding over time. While other bearings are best the day you buy them out of the box and degrade from there, XD-15 bearings improve over time, even years from now. We even offer a lifetime limited warranty to the original owner. You will not only save watts, you will save maintenance time. XD-15 is the pinnacle in bicycle bearing technology.

    Our XD-15 Pro bearing utilizes the same XD-15 steel as our Xd-15 Corsa bearing, only different in design. XD-15 Pro bearings are 15º angular contact sealed cartridge bearings. The bearing raceways are deep-groove to improve longevity and increase ball size. XD-15 Pro bearings use Grade 3 Silicon Nitride ceramic balls and are sealed on both sides using LLB Nitrile seals.
