Surly: Cross-Check Frameset - 2021

The Surly Cross Check frameset features a cool cross bike design but with a strong utilitarian appeal, its comfortable, versatile, tough as nails.


Pavement Bikes

Today's steel road bikes are tricky little buggers. Surly values steel pavement bikes that can go well beyond fresh asphalt, have accoutrements for various accessories, and won't leave you fighting a sore back for weeks after your ride. They design their steel road bikes for versatility rather than race results and the only wind tunnels they use are the ones that are attached to them.
