| Features |
Alpha Gold Aluminum frame Shimano 9-speed drivetrain Hayes hydraulic disc brakes Bontrager XR2 off-road tires Alpha Gold Aluminum: Our high-performance lightweight aluminum is continuously cold extruded and butted for weight reduction and superior strength. Frames built with Alpha Gold feature some degree of mechanical and hydroforming to create more sophisticated shapes for lighter weight, and are finished using Trek’s smooth-weld finishing process. Internal derailleur routing: Sleek ports at the head tube and near the seat tube let you run your front derailleur housing directly through the frame, keeping the cable protected from the elements and your bike running smooth, clean, and quiet. Rack & fender mounts: Built-in mounts make it easy to add racks and fenders for added versatility. |
