The DIMENSION project started with a clear target: the creation of an innovative product suitable for all categories of cyclists. This is why the Dimension line is extended and Dimension NDR is born. The NDR (born to be MTB oriented) has 3 mm extra padding than Dimension 143 in order to reduce all vibrations come off the ground. On the sides Prologo adds "side protector"ﾝ to avoid scratches or damages. The PAS system is a channel in the base of the saddle. The hole or channel helps to maximises blood flow and supports the pelvic area while also preventing pressure peaks. This system is designed and developed to eliminate pressure and numbness to areas that need it most. **Specs** * Size: 245x143mm * Rail: T4.0 7mm * Cover: Microfibre * Padding: Light Foam * Weight: 218g
