You want a reliable 29er mountain bike you can trust to get you out on the trails for some hassle free fun, and the overdrive sport is just the ticket. Its 6061-t6 aluminum alloy tubes are formed and butted for strength, but they also save weight to make your bike light and maneuverable. The machined head tube stiffens up the steering so you enjoy precise steering response and stout 29″ wheels, Shimano hydraulic disc brakes and a SR sun tour suspension fork ensure that you can handle whatever rolls your way.
