When conditions get challenging, Tektro Spyre-C mechanical disc brakes with 160mm rotors deliver dependable stopping power and control. Generous tyre clearance and Vee Tire Co. GPVee 40mm tyres provide grip and comfort across mixed surfaces, while the flared drop handlebar offers additional stability and control when riding off-road.
