Trek FX Sport AL 3 Rental Bike 2026 Cobra Blood

The FX Sport AL 3 is the bike for riders who spend most of their time on pavement but don't want to turn around when the road becomes gravel. Its lightweight Alpha Gold Aluminum frame, carbon fork, and upright riding position keep everyday rides feeling quick, comfortable, and ready for longer adventures.

Wide 700x42mm Bontrager Girona tires add grip on mixed surfaces, while Shimano's 10 speed CUES LINKGLIDE drivetrain is tuned for durability over high mileage. Hydraulic disc brakes provide dependable stopping power, and mounts for racks, fenders, bottles, and a top tube bag make it easy to adapt for commuting or all-day rides.
