The Open One + development team combines to Gerard Vroomen the virtues of a lightweight, uncompromising Cross Country frame with a bike for demanding trails and splinted intended use. Due to the special rear of Open One + this is compatible without restrictions with modern plus-size wheels. At the frame size adjusted wheel sizes optimize the bike for the actual driver and the intended use.
When Rahmenbau Hi is - modulus carbon used in aerospace, to meet its own high standards of the product. D abei is not about high or low -Modulus Carbon, it comes to the use of carbon in the right place (TRCinTRS).
The revised rear with floating axle as a connecting element between the impeller and frame, not only guarantees more stiffness but also lower weight. The choice fell on the X-12 BOOST standard, complete with its own 12x148 mm thru-axle. When BOOST standard chainring 3mm travels further outward, so the rear is at the same Q-factor 6mm wider than conventional hubs, thus the wheels are stiff, without any to it, the ergonomics is concerned restrictions.
Additionally ONE + chainstay were on OPEN lowered, which brings a bit more space for the drive train as well as for the strut itself. It can now be carried out even larger and more stable. For the comfort and enhanced traction, the leaf-spring-shaped seatstays are responsible (Wire stays).
The 12 mm ThruThread dropouts for floating axles combine the thread of the axle with the mounting of the derailleur hanger. So you have the advantage of rigidity through axle without additional extra weight of the mounts on the frame.
Even the choice of the bottom bracket, there are innovations. OPEN changes from known BBright standard to BB92. This step allows a variety of combinations crank for the frame and an improved weight / stiffness ratio in the bottom bracket.
Open Cycle frames are prepared for the future. Conversion to electric circuits with the current Shimano Di2 standard is the clever cable guides (optional) at any time. Also a loading with the hydraulic circuit components by Acros is not a problem.
