Ultralight Cassette & Rotor Lock Ring Socket


Sold Out

We travel a lot with our bikes and are always looking for the "leanest" way to have everything we need to build or service a bike without packing 50 lbs of tools!  To help with this we developed some very specific "travel tools" that are high quality but weight conscious for those that do a lot of mobile wrenching or traveling with their bike.  This light weight cassette and center lock brake rotor lock ring tool is precision CNC machined from hardened 4140 chrome-moly steel & nickel plated. As mentioned it is light weight and compact for your travel tool kit and mates perfectly with our Ultralight Lock Ring & Bottom Bracket Wrench.


  • 1 inch hex drive interface compatible
  • Fits Standard Cassette lock rings
    • Fits most cassette lockrings from Shimano, SRAM, SunTour, Chris King, and SunRace
  • Fits Centerlock rotor lock rings that use the same internal spline as the cassette lock ring
