    VBC 2x Chainring Hardware Sets

    These hardware sets are needed to mount VBC 2x chainrings to outer VBC 2x chainrings.  If you are purchasing a VBC chainring “set” the hardware is already included and the rings will be assembled together.  There are two types of VBC 2x chainrings, v1 for the older 9-11 speed rings, and v2 for the new 9-12 speed rings.  Refer to the tech docs below for information on how to identify which version rings you have and installation instructions.

    You would need a hardware set if:

    1. You are purchasing separate VBC 2x inner and outer rings
      1. You need this hardware to bolt the rings together
    2. You lost some of your hardware when working on your bike
    3. Some other odd reason we’re not aware of

    Bottom Bracket Bearings

    Product Details

    Since 1996 White Industries has partnered with the folks at Enduro to ensure that the bearings we install in all our products are of the highest standards.  Along the way Enduro has continually sought out better materials, seals, greases, tolerances and manufacturing techniques to stay on the cutting edge of bearing development and performance.  Our hubs come standard with Enduro high-carbon chromium steel bearings which have the best price/performance ratio, but if you are seeking the absolute pinnacle of bearing performance, we also offer Enduro XD15’s which features ceramic balls rotating in aerospace developed, nitrogen-infused, super-stainless-steel bearing races and come with a limited lifetime warranty.

    Specs

    • Bearings sold individually
    • Grey seals always face out
    • Green seals face out
    • Bearings should be installed using a bearing press
      • See Tools>Bearing Presses

    What’s In The Box

    • One bearing, sold individually

     

  • Bottom Bracket Spindle Spacer Kits

    Bottom Bracket Spindle Spacer Kits

    With all the different bottom bracket styles, frame manufacturers, and component makers out there you’re bound to run into situations where spindle spacers may be needed to make your particular frame/crank/bottom bracket combination fit correctly together.  Because there’s no way for us to know what your particular situation might be, we offer “kits” to cover a wide variety of combinations.

    We offer three spindle kits for 24mm, 29mm and 30mm spindles.  The 24mm and 30mm spindle kits also come with one “wavy” washer which goes on the spindle and acts as a bearing “preload” mechanism for crank arms that do not use a built-in bearing preload adjuster.

     

    Specs

    • The 24mm spindle kit includes:
      • Two .5mm spindle spacer, nylon
      • Three 1mm spindle spacers, aluminum
      • Two 2.5mm spindle spacers, aluminum
      • One 24mm wavy washer, steel
      • Spacers/wavy washer go between the bottom bracket seals and the crank arm
      • Fits 24mm spindle cranks such as Shimano, etc.

     

    • The 29mm spindle kit includes:
      • Two .5mm spindle spacer, nylon
      • Three 1mm spindle spacers, aluminum
      • Two 2.5mm spindle spacers, aluminum
      • No wavy washer
      • Spacers sit between the bottom bracket seals and the crank arm
      • Fits SRAM DUB 29mm spindle cranks

     

    • The 30mm spindle kit includes:
      • Two .5mm spindle spacer, nylon
      • Three 1mm spindle spacers, aluminum
      • Two 2.5mm spindle spacers, aluminum
      • One 30mm wavy washer, steel
      • Spacers/wavy washer sit between the bottom bracket seals and the crank arm
      • Fits 30mm spindle cranks such as White Industries, etc.

  • External T47 Bottom Bracket

    External T47 Bottom Bracket

    Product Details

    White Industries external T47 style bottom brackets are made here in our shop and feature Enduro stainless steel angular contact bearings or optional Enduro XD-15 ceramic-hybrid radial bearings.  We offer them with three different bearing sizes to help you fit your favorite crank to your favorite bike.  “T47” is a bottom bracket standard that White Industries helped develop in 2016 and allows for a greater weld area for bigger frame tubes as well as room inside the shell for internally routed cables and wires.

    The “T” stands for “threaded” and the “47” is the nominal 47mm outside thread diameter of the cup. T47 bottom bracket cups are not compatible with the much smaller (and more common) threaded BSA BB shells.  The “external” designation on this bottom bracket refers to the fact that the bearings sit “outboard” of 68mm and 73mm wide bottom bracket shells, as opposed to our “internal” T47 bottom brackets where the bearings sit “inboard” of 86mm and 92mm wide bottom bracket shells.  If you have an 86mm or 92mm wide T47 bottom bracket shell on your frame, you will need one of our “internal” T47 bottom brackets.

  • External PF30 Bottom Bracket

    External PF30 Bottom Bracket

    Product Details

    This is our PressFit 30 (PF30) bottom bracket system and incorporates a “thread-together” design that keeps the bearings aligned, prevents creaking and has a built in sleeve to protect against contamination as well as offering room for internal cable routing and wiring.  It is made in our shop and features Enduro stainless steel angular contact bearings or optional Enduro XD-15 ceramic-hybrid radial bearings.

    “PF30” is a bottom bracket shell type that was originally designed to use internal bearings (inside the BB shell) with a short, 30mm diameter crank spindle. With this thread-together bottom bracket we have located the bearings externally of the BB shell to work specifically with longer 30mm and 29mm crank spindles.

  • Press Fit 86/92 Bottom Bracket

    Press Fit 86/92 Bottom Bracket

    Product Details

    This bottom bracket is designed for 30mm spindle cranks installed into press fit style BB86 and BB92 bottom bracket shells that have an internal diameter of 41mm. It uses 30mm ID bearings to work with our MR30 series cranks as well as many other manufacturers that use 30mm spindles.  This unique design utilizes Enduro stainless steel double row flanged bearings that press directly into the BB shell.  This allows more room for bigger diameter balls as well as doubling the number of balls per side, both of which greatly increase the durability and life of the bearings.
