JAY sliding ring is an option to connect the CL and avoid the possible CL unhook of the sliding hook. Please check if the tube and lock mechanism of your CL can fit the ring size of 14mm. The pulley has a design to avoit full contact of it's sides to the steel parts. When you mount it take care not to lock the pulley by closing too much the ring's jaws when you screw the threaded pin.
Add a drop of Loctite to guarantee screw lock. To unlock it warm the steel around the screw thread in order to make the glue elastic.
