Simple, reliable and loads of fun, the aluminum Topstone is a gravel bike designed for those with a taste for adventure. Roll light and free, or pack it up for the long haul; The Topstone’s comfortable ride, confident handling and do-anything capability make it a perfect companion on any road, anywhere.
An extra-long offset at the fork axis together with a tumbled head angle achieve light and agile turning reaction, but also unbeatable stability at speed when the terrain gets rough. The frame accepts a 27.2mm diameter seat post with internal cable routing, so a dropper post could be fitted, which shouldn’t be a surprise on a true all-terrain bike.
