Go ahead, grab a gear or two, and sprint into the face of the next jump, Shimano's ZEE Rapidfire Plus Shifter proudly features the slick, definitive shifting that Shimano is revered for. It's a very linear effort, as you move up and down your cassette, meaning it takes the same pressure to shift, so you keep your mind on cranking out a proper whip. This 10-speed shifter sports 2-way release, so you can push or pull the trigger lever to fire off the shifts. The thumb paddle is lightly textured and shaped for perfect ergonomics and a wonderful feel, perfect for downhill, freeride, and dirt jumping.
