This full set comes with everything required for installation to replace your “E-Thru” thru axle. This includes: one Standard (or Boost) 12mm x 142mm (12mm x 148mm) thru axle, up to two Pitlock keys, and one thread socket.

The Set 24 and Set 24B Pitlock thru axles have the following specifications:

  • Installation width: 12mm x 142mm (Standard), 12mm x 148mm (Boost)
  • Total length: 170mm (Standard), 178mm (Boost)
  • Thread pitch: M12 x 1.5mm
  • Thread length: 20mm
  • Weight: 2.33oz (66g)
  • Color: black

Installation width is the width between the dropouts, or width of the front hub. Total length is the installation width plus width of the dropouts (the total length of the axle without head and lock.)

If you need additional keys, please order additional keys here: replacement keys. Thru axles use the same size key as the standard Pitlock “quick release” replacement skewers, not the larger Solid Axle keys. Unless you specify otherwise, we will ensure that the additional keys you order will match the coded set you’re given.

Additional details on “E-Thru” axles: this is a standard developed by Shimano, and several variants share the “E-Thru” name. As such, we highly recommend using the actual length of your existing thru axle to determine the correct size for your replacement. Please do not assume that because your frame is a Boost 148mm that it will require the Boost version from Pitlock. A standard E-Thru 142 axle will also fit many 148mm Boost frames.
