Delta Process Moulding


Don’t get excited. That’s top tube, not tube top. Now that we’ve cleared that up, let’s talk Delta Process Moulding (DPM). What is it? Well, it’s a newly designed shape that increases lateral stiffness. In other words, major performance.Think triangles – tubes are wider at headtube than at the seatube, both vertically and horizonally. This increases front triangle stiffness and front braking perfomance.
