I got a Nerve XC8 in July and it’s a fantastic bike with great spec/VFM, well saying that I’m doing my usual and upgrading bits fairly quickly (wheels, brakes, saddle, bars, grips, shifters, tyres and a reverb so far!).
So far I’ve done Glentress red and black bits, Dalbeattie, Kirroughtree, Carron Valley and Laggan and it manages everything easily.
Light enough on the ups and confidence inspiring going down.
Don’t worry about buying blind check the geometry against your old bikes as a guide for size and contact the U.K service centre if you have any questions.
