| Double Triangle Swingarm Project D.T.S.P. This suspension system used in Akita frame, designed for hard riding. Constant rotation, axis CNC milled components and smart construction are able to create a framework for geeks favorite 4x and slope style. Ease of driving combined with an adjustable suspension travel provides a lot of versatility. Low weight of this solution allows to create really light frame. After many successful seasons D.T.S.P. is a proven design for the advanced Riders. Duncon Dual Linkage System We began to develop this rear wheel suspension at the beginning of 2005. The main aim of our constructor, DunCon, was to create a system with a virtual axis of rotation which would not complicate the look of the frame, which optically was to consist of a classic front triangle and a swingarm on two small links. The D2LS was to be universal enough to be functional in downhill and enduro / freeride frames. At the beginning of 2006 we suggested two twin constructions: Tosa Inu as a freeride bike and Cane Corso as a downhill bike. Key features of D2LS: - the SAG suspension point is situated where the forces resulting from pedalling are ignored, so there is no ‘rocking,it does not matter whether the rider is sitting on the saddle or standing on the pedals. -the path the rear wheel follows is a fragment of a parabola and not an arch. - D2LS does not require the use of an intermittent brake clamp, braking has a marginal influence on the work of the suspension. - suspension is progressive, which prevents a frequent driving in of the damper. - placing three important elements of a frame in one milled aluminium block; two axes of rotation and a support axis, allows a considerable increase in the hardness of the suspension in the place where the greatest forces, coming from suspension, influence the frame. On the track, the rear wheel is in constant contact with the ground (provided the damper is positioned correctly), and the costructionally designed point of suspension stabilisation, situated at the back of SAG, allows the use of back shock absorbers without a platform in downhill biking. The progressive character of the end of rear wheel travel in the DDLS makes the suspension very sensitive to minor unevenness and, at the same time, resistant to great unevenness, driving in the damper. A slight increase in the damper progression is enough to ‘programme’ the suspension to be completely resistant to driving in.
