ADAPTOR,MIRROR 10 TO 8MM
A threaded adaptor that converts a 10mm mirror stud down to 8mm.
This is a mirror stem adaptor that steps a 10mm thread down to 8mm, letting you run a mirror with one thread size in a mount or lever perch drilled for the other. It is a small, simple piece of hardware, but it solves a common headache when the mirror you have on hand does not match the threading on the bike or lever assembly it needs to bolt to.

The part also shows up in our records under 20-28111 and JRC 28111, which are just different catalog forms of the same adaptor. If you are trying to true up mismatched mirror threads on a British bike build, this is the kind of fitting that gets the job done without swapping mirrors or levers.
We do not have a lot of extra detail on file beyond what the catalog lists, so if you have a specific application in mind, give us a call and we can talk through it before you order.
