A capable, versatile gravel road bike. Built for chasing horizons, exploring routes less travelled or accelerating your commute. A balanced riding position: upright enough for comfort over the long haul and control on technical terrain, yet still low and forward enough for speedy efficiency.
Built with plenty of room for tyres up to 42mm wide, for comfort, grip and adventurous capability. With mounts for three waterbottles, plus mounts for top tube storage, Topstone is ready to go long. Multiple bottle cage positions on the downtube mount let you configure for big frame bags.
