Trek Roscoe 8 Mountain Bike 2022
A no-nonsense hardtail built for good times only, the Trek Roscoe 8 Mountain Bike is a quality choice for those hunting out rowdy lines on grin-inducing terrain. The 29” wheels are rapid along undulating trails, holding their speed and providing superior performance when the track gets rough. These are clad in tacky 2.6” tyres for supreme grip, while the 140mm RockShox 35 Gold RL suspension fork irons out roots and rocks.
The frame features an Alpha Gold aluminium construction, complete with a tapered headtube and dropper seatpost routing, ensuring lightweight performance and bombproof durability. A Bontrager cockpit offers high levels of control, while their Line Comp 30 wheels shrug off big knocks with ease.
