Seat tube. A special project in itself. It is not only hydroformed to achieve the desired shape, but also butted. By bulging the centre section, we eliminated the need to weld on a rocker mount, opting instead for a stronger piercing for the oversized pivots. Finally, we shaped and flattened the seat tube to allow for tire clearance with a 29” x 2.3” tire. Open Headtube. Patented design for stiffer, lighter headtube junction. This design means that both tubes are mitred to meet each other at the headtube junction rather than just one, creating a large, open box section. This removes unnecessary material while maintaining exceptional stiffness.
