TRP EVO DH-R brakes provide strong, consistent braking with large rotors for control on long, sustained descents.Finished with wide Giant TRA 2 rims and Maxxis Assegai tyres front and rear, the Reign SX is set up for grip, support and reliability. It’s a purpose-built enduro machine for riders who want confidence and composure when the trail points straight down.
