Ride Brilliantly

On every ride, SmartSense has your back. With SmartSense’s system of rear-facing radar and intelligent lights increasing your awareness and visibility out on the open road, it’s never been easier to ride smart.

Features

Dropper Ready

Built to accept an internally-routed 27.2mm dropper seatpost, which shouldn’t really be a surprise on a bike this off-road capable.

Engineered Simplicity

Low-friction bushings on the Kingpin thru-axle offer smooth action, maintenance-free reliability and over 100 grams of weight savings vs conventional cartridge bearings.

Clearance and Compatibility

The new dropped chainstay design lets you run big volume tires (up to 700x45mm or 27.5×2.1″, with 6mm of mud-shedding clearance on each side), all with a standard dish rear wheel for easy interchangeability.
