If your bicycle has solid axles, Pitlock’s M10 set, double or single, should be compatible.
Please keep these conditions in mind before implementing Pitlock:
The protruding thread should extend about 14 mm out of the dropout in order to securely install Pitlock. If the protruding thread is too short, you will need to use an axle stub with a long threaded axle (available for purchase from Rohloff.)
Make sure that the threads protrude far enough so that there is enough space for the security ring and the locking mechanism can be assembled correctly.
Be sure to grease the thread before assembling.
