Joker Machine 03-025R Metric Mirror Adapter

10mm metric mirror adapter enables you to mount mirrors with 5/16in.-24 mounts on metric bike controls. Super low-profile design keeps the mirror base looking clean, opposed to some aftermarket messy looking adapters out there on the market. Available in a right thread 10mm on one end and threaded 5/16in.-24 on the other. Heat treated alloy threaded stud and stainless steel jam nut included. Installs in seconds with an Allen wrench. You need one adapter for each mirror. Made in the USA.
