mountain Fullsuspension
Dual Trail Control, DTC for short, is a rear suspension system further developed by us and now in its 2nd generation form, in which the shock absorber is controlled simultaneously from the chain stay and linkage, i.e. is suspended as if floating in the rear suspension. This and the kinematics selected to match the intended use leads to a situation with our DTC models, where a very sensitive suspension response is guaranteed and at the same time the rear suspension displays absolutely no “seesawing” with the associated power loss.
Why a lockout when the rear suspension doesn’t seesaw anyway due to its kinematics? We have implemented this different on the various DTC models in accordance with the intended purpose. The STING and the STEREO, perceived as a Marathon (Sting), XC (Sting) and All mountain (Stereo HPC, Stereo and Stereo WLS) bikes have the most strongly pronounced Anti-Seesaw kinematics. The Fritzz, our Enduro Bike, still displays very good Anti-Seesaw behaviour with at the same time optimised downhill ride characteristics which are really fun. Naturally we also use here for each model an individual shock absorber specially developed in collaboration with FOX Racing Shox.
How do the various Dual Trail Control models differ? The STING SUPER HPC. Top model in the DTC Series, For Marathon, Alpencross, Allmountain Sport, 120 mm suspension travel, carbon, no seesawing. Our Sting Super HPC is our cutting edge innovation bike. Light due to Advanced Twin Mould Process. In this way we achieve a very good stability and rigidity to weight ratio using High Performance Composites and the consequent reduced use of resin. Top kinematics specially tuned for use as a marathon and CC bike. A
bike which takes you uphill without seesawing which wastes effort but which also displays outstanding suspension sensitivity and performance. Best possible rigidity values due to optimised tubing cross-sections and joints, e.g. to the bottom bracket bearing housing. This is especially wide in order to accept the Shimano press-fit bottom bracket. In that way we achieve maximum bearing support width and make possible even more efficient power transmission. In order to be able to use suspension forks with tapered head tubes (significantly greater rigidity) we have also designed the frame head tube accordingly. This again results in even better rigidity values due to the possibility of having a greater crosssection at the down tube-head tube joint. In addition here, as on the Stereo and Fritzz models we also use the Syntacedeveloped X12 through-axle. With all these measures we have succeeded in developing a bike which sets new standards both in design and in function.
The STEREO HPC. In 2010 we are expanding our DTC model range with the STEREO HPC. On this bike we are only using carbon material on the main frame, this conditioned by optional use in heavy terrain, due to the possible suspension travel. Here too High Performance Composites are used as on the Sting Super HPC. However the frames are produced in an already forward-developed improved Advanced Twin Mould process. Parallel to the Sting Super HPC for reasons of rigidity we are also using the Shimano press-fit bottom bracket and the conical head tube here in order to fit suspension forks with a conical head tube. A further highlight on this model is control line routing for the shift cables designed inside the frame. The highlight on this model is plainly that with identical geometry and ride characteristics the bike is significantly lighter than the Stereo HPA.
