It’s never easy to spec the ultimate jumping frame but that’s exactly what tried to do – with feedback from like-minded

Welded brake mounts were a priority. We wanted a long headtube to minimize the need for both spacers and steerer tube cutting. We specced double head tube gussets for maximum strength. We wanted a drop out with integrated chain tensioners that would be immediately recognisable, a wider tapered BB and a seat-tube cable stop.

Above all we wanted stable geometry and the butted/tapered tubing that most of our competitors struggle to supply.
