The weight optimised 611 Ergowave active Carbon was precisely designed to accomodate the requirements of off-road cycling and perfectly meet the demands of All Mountain and Enduro use. With just 225g the 611 Ergowave active Carbon is the lightest 611 Ergowave model with active technology. The wave-like shape and raised rear section provides perfect rearward support and an optimal pressure distribution which reaches deep into the body structures resulting in improved power transmission. The lowered nose in combination with the dip provides optimal pressure relief for the perineal area. For an even better pressure relief, especially on long technical climbs, the saddle nose of the 611 was made approx. 4mm wider than that of the 612, but just as flat and with largest possible surface area. The padding was designed for the specific needs on the MTB with better dampening properties than the 612 making it perfect for rough off-road terrain. Additionally, a premium quality Kevlar material protects the saddle in the exposed places. The SQlab active technology allows the saddle to follow the biomechanical motion when pedalling resulting in increased comfort, mobilisation of the spinal discs and reduced pressure to the sitbones. Note on compatability of carbon rails Ensure that the seatrail clamping mechanism of your seatpost is compatible with oval shaped seatrails. In some cases, specific seatrail clamps are available seperately to allow the fitting of saddles with oval shaped rails Area of use MTB Tech Trail Length mm 280 Weight g 191-199g Material Rails S-Tube oval shape 7 x 9.6 mm Material Cover C84 Kevlar max.
