Zee is Shimano’s new line of Gravity-specific components, for those of us who do not have multi-million dollar sponsors. The 10 speed Zee RD-M640 features Shimano's premier Shadow Plus technology, which introduces a switchable friction clutch into the rear linkage that significantly reduces chain noise and offers a more stable drivetrain through rough terrain. With a flick of an anodized gold switch, it also virtually eliminates chain slap, makes changing out rear wheels easier, and reduces the possibility of dropping your chain.
Zee is tuned specifically for 1x10 applications, although narrow range 2x10 applications will also work with this derailleur so long as extreme gear combinations are not used. The Zee derailleur is offered in two short cage (SS) configurations: DH and FR. The DH derailleur has a specific actuation arc that will closely follow closely spaced DH ratio cassettes, up to 11-28T. The FR version is designed for riders who hit more varied terrain, and want to go uphill as well as downhill, featuring capacity up to 11-36T cassettes.
Feature-packed, and surprisingly light, the Zee rear derailleur is designed specifically for hard gravity riders on a budget, because everyone, not just the pros, should be able to crush lines.
