That isn't to stay that you should settle into the sofa with a cup of tea and binge watch your latest go-to series, but rather, pack on your best winter gear and meet him head on as you rocket down sparsely populated trails and crush frost coated climbs.

The outsole itself is built from carbon reinforced nylon, designed for stiffness on the bike that maximizes your power transfer, and just a touch of flex when you're off, allowing torsional flex ...
