ALS II CHASSIS TECHNOLOGY
Active Linkage System II, that is the new ROTWILD suspension technology, optimised for the demands of tough racing conditions. With the ALS II the perfect chain stay technology is available: Completely driveneutral, permanently open and active. Making it unbeatable in traction and thrust. Full function uphill, in the sprint and in fast downhill rides: The intelligently designed chain stay in combination with the specially matched shock absorbers make an open suspension system, which functions permanently and without sophisticated special technical solutions, possible. When the maximum spring defl ection becomes necessary downhill, it makes its reserves available. The ALS II provides 110 mm spring defl ection for fast and demanding downhill rides, without negatively affecting the thrust. To improve the traction of the chain
stay, special development emphasis was placed on the transfer ratios of the chain stay. The ALS chain stay turns with a constant radius around a fi xed pivot point, the lever ratio stays unchanged over the whole spring defl ection range. Ideal for optimal shock absorber setup, so that the chain stay can respond particularly fast for maximum traction and riding dynamics. Supported by new, fully fi lled and sealed industrial ball bearings, which ensure extremely sensitive responding properties at high mileage. The normal drive and braking reactions are unnoticeable. Efficient, lightweight, resilient and overall with maximum performance. No other system allows for lighter construction and is more suitable for racing use. The ALS II is an integral component of the new R.R2 frame concept with a thrust action never experienced before.
