Out on the trail

With its 11-speed Shimano Cues system and 11-50t cassette, the bike shifts smoothly on technical climbs and provides a low enough gear to help you maintain your rhythm even on the steepest forest tracks.

On all-day rides, the aluminium frame with its modern geometry and 2.40-inch-wide Kenda Booster tyres provide stability and reduce fatigue by effectively absorbing smaller bumps in the trail.

On fast descents, Shimano MT200 hydraulic disc brakes provide reliable stopping power, while the SR Suntour front suspension keeps the front wheel in consistent contact with the ground over roots and rocks.
