But that's not all -this trail-tuned design boasts a balanced geometry with a 75-degree seattube angle for powerful pedaling on climbs, and a slacker 66-degree head angle for boosted confidence and control on technical descents. Plus, the lightweight ALUXX SL aluminum hardtail frame offers nimble acceleration and maneuverability, so you can climb, corner, and hammer the flats with ease.

The most accurate way to determine any bike’s weight is to have your local Bicycle Warehouse weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
