Product Review

The ZEE SL-M640 Shifter works with Shimano's 10-speed derailleurs to provide consistent and precise shifts. Using Rapid Fire Plus and two-way release, the ZEE shifts just as well as SLX but uses shorter paddles for DH, FR, and jump bikes. The textured shifter levers add an intuitive element to Shimano's ZEE SL-M640, and it uses a one-bolt clamp to fasten to handlebars.
