Description
The new Marin Alpine Trail Series 4 aluminum MultiTrac 2 LT frames feature mixed 29"/27.5" wheels, 170mm front and 160mm rear travel, and the utmost in adjustability. Riders can alter the head tube angle and bottom bracket/chainstay length, as well as run 29" rear wheels if desired. "Bear Box" downtube storage includes a zippered nylon bag to house trail essentials, and a 34.9mm seat post increases strength and is compatible with the latest dropper posts. "XR" = "Xtra Rad" at Marin, and like the XR models that have preceded the new Alpine Trail, we created a model for the more discerning rider. We focused our efforts on building a bike with high performance RockShox Ultimate-level suspension, a SRAM GX Eagle Lunar 12-speed drivetrain and DB8 4-piston brakes - all equipment that helps the rider level up, but without blowing the budget. Don't forget the Maxxis rubber and our proprietary CNC machined 35mm stem and matching Trail Bar.
