Wide Bontrager Line Comp 30 Tubeless Ready wheels provide stability, improved grip, and reduced risk of punctures, making them ideal for aggressive trail riding.

The drivetrain uses SRAM’s wireless GX Eagle AXS transmission, offering smooth, reliable, and precise electronic shifting across 12 speeds.
