MisMatch adaptors allow users to mount Shimano & SRAM brakes and shifters on one clamp. Available in multiple configurations. Compatibility (Updated 7/17/2017): MisMatch adapters and the ever evolving "standards" it attempts to integrate between SRAM and Shimano is a confusing subject. Shimano brake and shifter mounting options have changed a lot, going through four mounting systems from 2011-2016. Shimano brakes have a model number printed somewhere on the brake and shifter, and this is the best way to determine what you own and what adaptor you need.
