Specifically designed as a rear-only lever for 1×10 drivetrains, the M640 Zee shifter features crisp, consistent Dyna-Sys shifts and 2-way release. The Zee shifter’s ergonomics make for an extremely comfortable, intuitive setup for the best performance when ascending or descending. The lever body is built for hard wear and tough usage, to continue working even after impact. Paired up with a Zee or Saint rear derailleur, you will be equipped to tackle any trail, no matter how gnarly.
