Product Review

Borrowing the powerful 4-piston caliper from Shimano's World Cup dominating Saint, the Shimano ZEE BL-M640 Disc Brake instills confidence into your riding with its brute stopping force and precise modulation. Ideal for trail and enduro rigs, the ZEE Brake resists fade on long downhill sections, thanks to its heat-dispersing 4-piston caliper design and improved pads with a new metallic compound for better consistency and control on the descent. Featuring Sero-Wave actuation with greater lever travel off the top, the ZEE allows its braking pads to sit farther from the rotor, reducing the chance of nasty brake rub, while providing a powerful bite for fast stopping. Its Shorty levers are almost identical to what you'd find on Shimano's SLX brakes. However, they exchange tool-free reach for a dimpled, non-slip lever surface. This gives you added control when your hands are damp from perspiration, retaining reach-adjustment with an Allen wrench for a customizable trigger feel. Note that the Zee Brake is available in either left or right options. Disc rotors and brake adapters are not included.
