Shiftmate 6

Combining Shimano with SRAM: the Shiftmate 6 by Jtek Engineering
The Jtek Shiftmate adapts the transmission ratios of incompatible shift components to each other. The shifter cable runs through the Shiftmate, which uses a special shifting wheel to change the cable ratio and match the shift levers.
The Shiftmate 6 (Shiftmate Straight) lets you combine Shimano shifter grips with SRAM 1:1 rear derailleurs, or SRAM offroad shifter grips with Shimano rear derailleurs. It is also possible to combine Shimano 10-speed Road STIs with Shimano MTB 10-speed Dyna-Sys rear derailleurs and Shimano or SRAM cassettes.
Jtek Engineering was founded in 2003 in the USA and is now based in Great Britain. It offers high quality and well thought-out products that can be used to solve compatibility problems in an elegant way.
