Trek's Superfly SS offers pro-level handling with the let's-go-shred-everyday reliability that only a rigid singlespeed can offer. You'll charge on the light, efficient aluminum frame with proven G2 geometry, tapered head tube, press-fit BB, and sliding rear through axle. Up front, a 15mm through axle connects the rigid carbon fork to the 29-inch tubeless-ready wheels and tires that roll over practically anything. The singlespeed simplicity lets you focus solely on the trail ahead, and it keeps the the bike feather light, too. It also has Shimano disc brakes and Bontrager bar, stem, and seatpost so you're ready for anything from scorching the local trails to winning races on the weekends.
