Why riders pick it
- 170mm front and rear travel on a 4-bar carbon frame soaks up big hits and rough lines.
- Bosch Performance CX drive with a 600Wh PowerTube replaces the shuttle or chairlift.
- SRAM 70 Eagle T-Type 12-speed with a 10-52 cassette and a OneUp chainguide keep the drivetrain secure on rough ground.
- SRAM DB8 brakes on 220mm and 200mm rotors are sized for long, steep descents.
- Maxxis Assegai and Minion DHRII tires on Double Down casings for grip and puncture protection.
