The new Ergon SM Sport Men s Saddle has been specifically tailored to the features of the male anatomy and optimized for the requirements of mountain biking. With the assistance of the latest scientific studies and intensive prototyping, Ergon s interdisciplinary development team consisting of sports scientists, industrial designers, engineers and test riders have come up with a new generation of pressure-relief men s saddles. Large-Area Pressure Distribution: Perfect pressure distribution in the sit and pubic bones by means of a flat, even contact area and high-end padding foams.Flat Rear: The narrow, slightly inclining rear with a flat contour and a minimal ramp-up give great freedom of movement on the downhills.Flat contour: Due to the more upright pelvic orientation the saddle surface is flat with great freedom of movement.Integrated Mount: Convenient removable mount for accessories like Topeak saddle bags.Shape: Through its Y-Shape the freedom of movement and legroom are maximized, while at the same time all bone structures are ideally supported.The SM Men saddles effectively avoid discomfort and numbness for most applications in mountain biking, for most types of mountain bike riders. They offer effective relief with the extremely deep and rearward increasing relief channel is complimented by a proper cut-out in the deepest spot. This construction combines all the benefits of a standard cut-out saddle without its drawbacks (often a very stiff shell) producing a particularly high degree of pressure relief of the sensitive perineal area. Exceedingly high pressures often are the cause for discomfort and numbness in the genital area.Shell: Nylon CompositeRails: CroMoCover: MicrofibrePadding: Orthopaedic Comfort FoamWeight: 305g (S/M), 325g (M/L)Size guide:Small/Medium: 9-12cm Sit bone widthMedium/Large: 12-16cm Sit bone width
