When the gravel roads are calling we get rolling on the HED Emporia GC3 Performance Disc Wheelset and set out to conquer the wildest the hills have to throw our way. These wheels are designed for gravel bikes, featuring 12mm front and rear thru-axles and a rim width that's ideal for tires 35mm - 55mm wide. When the roughest roads are out to get us these carbon hoops have us gliding over the terrain and quick to get rolling.
