Trek Roscoe 9 first ride review

Jul 2018 · Guy Kesteven

The big tyres also hide the primitive fork damping pretty well, and while the geometry isn’t radical (a 68-degree head angle, 440mm reach and 1,155mm wheelbase on the large), you can properly rag the Trek on natural trails or nurtured red routes.. .

Trek Roscoe 9 review

Apr 2018

Trek's Roscoe 9 marries an aluminium frame with trail riding orientated geometry to chubby 2.8" Plus tyres on 27.5" rims. While it doesn't jam in as much value as direct sales rivals, it more than makes up for that with a fun, refined ride and coherent kit list. Review: Genesis Tarn 20 - a steel framed Plus tyre trail hardtail Buying your first mountain bike: our guide to everything you need to know Review: Trek Fuel EX5 Women's 27.5 Plus - confidence inspiring Plus trail susser The Roscoe is a bit of a departure for Trek.
