Aim at AX Lightness was to develop a possible lightweight, yet fully compatible framework with best mechanical properties. The key data are convincing:
- Comfort-oriented geometry with longer head tubes
- Complete new development with reduced tube cross sections
- Double Tubing: raise extra body inside the frame stiffness
- Vertical compliance in rear and seat tube for appreciable comfort
- Better aerodynamics
- Internal cable routing
- Di2 compatible
- Sub 700 grams to size L
Already the Vial put a benchmark in terms of bottom bracket stiffness and comfort. Such a benchmark to set a good bit higher without accepting losses elsewhere is not without new concepts. The objective: optimizing anyway optimal.
Improving the comfort value and aerodynamics could shrink many pipe diameters. To simultaneously set stiffness in the bottom bracket and head tube again at the highest level has placed at certain points of the frame structures inside AX Lightness. A lot of effort but in cover worth of rigidity. Comfort is more important than ease. The Vial Evo is one of the lightest frames in the world, but to be on longer trips relaxed mobile. For the rear and the seat tube has a special design, which allows a vertical flex. The bearing diameter of the lower tax warehouse was reduced to 1 ¼ ", for such forks offer noticeably more flex where you need it. At the same time grow the headtube and allow a relaxed position in the top link Spacertürme. An optical Bonus for your bicycle.
The frameset Vial EVO D has the super light and stiff THM Scapula CT. The scapula CT corresponds to the racers for the lowest weight. With only 275 grams, the fork marks the peak of what is currently feasible.
No other road bike fork reaches the same low weight with full racing prowess. The stiffness values are well above average and are thanks to the geometry of the stem / fork crown even slightly above the Scapula SP. The lateral stiffness (55N / mm), important for hard sprints and precise cornering, despite the low weight is very high. Simultaneously THM has managed the balancing act to construct the fork extremely comfortable. The central feature of the scapula CT are the continuous fibers from the stem to the dropouts, which have a bearing structure made of carbon fiber.
The wall thickness of the shaft and the fork blades are continuously graded, according to the acting forces. Due to the different forces in the direction of travel and transversely thereto results in an elliptical inner cross section of the supporting structure of the shaft.
