The ShiftMate Straight is an inline shifting interface device for mating different bicycle shifting components. Using a ratio changing pulley, the ShiftMate Straight adapts different component brands and models to make the proper correction in the amount of cable pull needed for perfect shifting.

– CNC machined.
– Sealed ball bearing.
– Hard Nickel plating.
– Ideal for straight cable run mounting or mounting at cable stop locations.

This model is for mating older Pre-2001 8 & 9 speed Campagnolo components with Shimano 8 & 9 speed components. You can also match newer Campagnolo 11 speed with Shimano 10 speed components.

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.

*Except Shimano Tiagra 4700 10 speed shifters and rear derailleur

2001 and newer Campagnolo shifters and derailleurs are not compatible with older versions.

For installation you will require a gear cable end cap with an external diameter of 5.3mm.
The Clarks Plastic Gear Ferrule for 4 mm Gear Outer Cable meets this specification (SJSCycles part 5269)
