The Prologo Dimension T4.0 143mm Road Saddle has been tailored towards optimum performance and comfort, with a focus on preventing perineal area problems. With its short nose and T4.0 rail construction, the overall weight has been brought down to a mere 149 grams while the 143mm width aids weight distribution for long distance comfort. Additionally, the PAS channel that runs along the centre of the saddle helps to reduce numbness. With its light foam padding and ergonomic profile, the Dimension is 143mm wide, perfect for tackling long distance rides at speed. Completed with a wide anatomical 'PAS' channel along the saddles' centre, pressure buildups are reduced, removing unwanted numbness during tough rides.
