Introducing Zee: Gravity Components for a New Generation
Shimano introduces Zee, a new line of gravity components that are an ideal starting point for**aggressive riders and racers. Zee is the gateway gravity component line that allows riders to get**on board with Shimano’s gravity program and experience premium new component**technologies at a price they can afford.
Highlights in the Zee line include a 10-speed system that**comes standard with new ICE Tech and Shadow Plus technologies.

• Zee Shadow Plus RD – The Zee RD-M640 features Shadow Plus technology proven to**reduce chain slap, drop and impact noise and the 10-speed short cage RD’s low profile**tucks safely below the cassette cogs.


Zee RD-M640 features Shadow Plus Technology

With two spec options that enable a typical MTB**cassette (11-32,11-34,11-36) or a close ratio road cassette (11-23,11-25,11-28), Zee is**ready to handle the needs of enduro and DH racers. 10-speed also offers complete**compatibility with Dyna-Sys MTB product and Shimano’s latest chain and cassette**technology.

• New gravity 10-speed shifter – The new Zee shifter uses Dyna-Sys compatible cable**stroke, which means linear shift effort, easy set-up and accurate, stable gear changes.**All new paddle shapes with 2-Way release and dimpled main lever allow riders to be**more in control and perfectly engaged.



• Powerful 4-piston Disc Brakes with ICE Tech – New Zee hydraulic disc brake**systems are gravity rated with a Servo-Wave brake lever and new 4-piston ceramic disc**brake caliper. System stiffness is tuned using Shimano’s high-power hose and shorter**lever blade while ergonomics are perfected with a new pivot location and dimpled**surface. ICE Tech brake pad and rotor options reduce heat in the system and maintain**performance on the longest descents.
