Trek's Superfly 100 AL offers pro-level handling and speed at a price that even un-sponsored racers can afford. And, even if you never race it, you'll love the light, efficient aluminum frame with G2 geometry for amazing handling, the 100/110mm front/rear travel for total control and the 29-inch tubeless-ready Bontrager wheels and tires for rolling over anything. Also, a short wheelbase and the custom Fox fork deliver power on the climbs, control on the descents and all the benefits of big wheels with super-quick handling and snappy steering. And, in the components department, you get a solid SRAM X7 parts group, powerful Avid disc brakes and Bontrager controls so you're ready for anything from throwing down on local trails to racing on the weekend.
