Ultralight Lock Ring & Bottom Bracket Wrench


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 Ultralight Lock Ring & Bottom Bracket Wrench is has features a 1 inch hex at one end and a external BB cup spline at the other end (also often used for center lock rotors).  The 1 inch hex end features magnets that quickly couple it to useful tools like our Ultralight Cassette & Rotor Lock Ring Socket.  Wolf Tooth is also working other 1" hex inserts for this tool!


  • 1 inch hex drive at one end and 16 notch 44 mm bottom bracket tool (or center lock rotor tool) at the other end
