Better spec
More robust Bontrager XR-2 tires, oversize 31.8mm handlebars, and 9-speed throughout. New 4900 model has 3x10 drivetrain!
-
Outstanding warranty
Built to last, and backed by Trek's limited lifetime warranty.

Mountain-tough frame
A trail ready Alpha Gold Aluminum frame, with gussets and monostay seatstay.
-
Perfect fit
The best fitting bike is the best riding bike. Our extended sizing range guarantees that every rider gets the perfect fit.
The 4300's frame has nice lines thanks to its formed tubing, and it's strong and stiff courtesy of gusseting in key areas. Trek uses lightweight Alpha Black Aluminum on the 4300 to keep its weight to a minimum.
