Jtek Engineering Shiftmate 8A Circuit Converter

Shimano Road 11-speed combined with MTB 11-speed: the Shiftmate 8A from 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.
With the Shiftmate 8A (Shiftmate Barrel) you can combine Shimano Road 11-speed STIs with Shimano MTB 11-speed derailleurs. This means you can use racing bike handlebars while having access to an off-road gradation, such as on a cyclocross bike. If you want to go in the other direction, i.e. use a Shimano MTB 11-speed shifter with Shimano 11-speed road rear derailleur, mount the Shiftmate onto the shifter handlebar.
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.
