The 611 ERGOWAVE active Flow Yellow is identical in construction to the 611 ERGOWAVE active S-Tube model with integrated active technology except for the Kevlar edge protector. It has been precisely adapted to the needs of off-road use as well as to the requirements of all-mountain and enduro riding. The saddle's wave-like shape and raised rear provide perfect rear support and optimum pressure distribution down to the deep structures of the body, which significantly improves power transmission to the pedal. The lower lying nose in combination with the deepening in the middle creates more space for the dam area. The saddle nose of the 611 is approx. 4 mm wider than that of the 612 for even better pressure relief, especially on longer ascents in off-road terrain, but is just as flat and designed with as large a contact surface as possible. The upholstery material was specially adapted to the MTB requirements and has more damping in rough terrain than the 612 ERGOWAVE models. High-quality Kevlar cover protects the particularly stressed areas on the saddle. The SQlab active saddle technology allows the saddle to follow the pedalling movement, increasing comfort, mobilising the intervertebral discs and minimising pressure on the seat bones.
