Jtek Shiftmate 3

This model is for mating newer 2001+ Campagnolo 9 & 10 speed components with Shimano 9 & 10 speed components.

– Shimano 9 & 10 speed shifters to Campagnolo 9 & 10 speed cassettes & derailleur
– Campagnolo 9 & 10 speed shifters to Shimano 9 & 10 speed cassettes & derailleur

Using a ratio changing pulley, the ShiftMate adapts different component brands and models to make the proper correction in the amount of cable pull needed for perfect shifting. There are no comprimises when using a ShiftMate. Your shifting will perform equally or better than original factory components.

ShiftMate features and benefits:
CNC machined
Sealed ball bearing
Reduces cable friction and cable housing length
Wide range of component mates & interfacing
Small compact design only 12 grams
Save money by upgrading over time or using components and wheelsets you already own.
