(4 customer reviews)

From: $72.99

Upgrade your rear Maxle with the unmatched security of Pitlock. Set 20 is compatible with rear wheels using Rockshox Maxle thru axle mounts.

This set can be purchased in two lengths: Standard or Boost. Standard installation width (the hub width) is 12mm x 142mm, and Boost installation width (the hub width) is 12mm x 148mm. The total length of the standard and boost thru axles is 174mm and 179mm respectively. You may see different lengths advertised on other websites, but this length is correct (see the photos) and is what is labeled on the packaging itself. This set comes with all the necessary components for installation: one black thru axle, and up to two keys.

See below for additional product and sizing specifications.

This thru axle provides security for 12mm x 142mm (or 12mm x 148mm for Boost) rear Maxle thru axle mounts. The set comes complete with the following: one black thru axle, and up to two keys.

The Set 20 and Set 20B Pitlock thru axles have the following specifications:

  • Installation width (hub width): 12mm x 142mm (Standard), 12mm x 148mm (Boost)
  • Total length: 174mm (Standard), 179mm (Boost)
  • Thread pitch: M12 x 1.75mm
  • Thread length: 20mm
  • Weight: 2.40oz (68g)
  • 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: for installation, this Pitlock thru axle will require a flat surface area of approximately 22mm in diameter.
