Information

We offer axle kits for all our current model hubs and some discontinued models.  If you don’t see a particular axle kit listed for your hub, that means it’s not compatible with your hub.  Please read all the information below to help direct you to the correct kit for your hub.

Features

• Axle kits do not include bearings unless otherwise specified
• Axle kits include (these are the names of the parts):
  • “Axle Tube” with the “Press-On End” installed
  • “Adjustable Axle End”
  • “Bearing Preload Collar” (the part with the set screws)

Front Axle Specs

• Boost axle kits are not compatible with non-Boost hubs and vice versa
• We do make a Non-Boost to Boost spacer for CLD and XMR hubs (Part# AXLEND17FABOOST)
  • Requires you to redish your wheel and is only compatible with 15mm x 100mm Thru axle kits
• Part # QRPLUGS is/are only compatible with newer style 15mm x 100mm Thru axle kits (CLD, Mi5, XMR)
  • Removable QR plugs have a 2mm hole cross-drilled through the 9mm axle end to allow for easy removal using a 2mm hex key

Rear Axle Specs

• Boost axle kits are not compatible with non-Boost hubs and vice versa
  • There are aftermarket kits that will convert 12mm x 142mm Thru axle to 12mm x 148mm Boost
    • We do not make these kits
    • We don’t know how well they work
    • They will void our warranty
• Rear hubs with our Shimano Micro Spline drivers require different axle kit than other drivers
  • If you are swapping to or from a Micro Spline driver, you will need to purchase the correct axle kit for the new driver

Mi5 front hubs

• There were 2 types of axle systems used in these hubs
  • Newer Mi5 hubs have removable QR plugs with 2mm cross-drilled holes in the 9mm axle ends that pop out to convert to a 15 Thru axle
  • Older Mi5 hubs do not have removable QR plugs ( no 2mm cross-drilled holes in the 9mm axle ends)
    • When replacing axles on these older hubs you will need to purchase part # KITFQRMI6 which comes with bearings

Mi5 rear hubs

• There were 2 versions of  these hubs, each with different hub shells
• Older Mi5 “10 speed” hubs use Shimano HG 10 speed, SRAM XD (not XDR), or Campy 10 speed drivers
  • When ordering an axle for these hubs make sure you choose the Mi6/Mi5 “10 speed” option
• Newer/current Mi5 hubs use Shimano HG 11 speed, Shimano Micro Spline, SRAM XDR, or Campy 11 speed drivers
  • When ordering an axle for these hubs make sure you choose the Mi5 “11 speed” option
