The Scratch Pro Nack is part of the Prologo round shape range of saddles using the Nack, Active Density and ESD technologies. Increased seating area for your inner tights, better support to the pelvic zone, less seating options than the other shapes. Ideal for the cyclist that likes to keep the same position for long rides.

technologies

Active Density
A new solution patented by Prologo that allows a new level of comfort. This system is actually a combination between MULTIPLE STIFFNESS and MULTIPLE DENSITY

ESD
The Easy Stroke Design (ESD) is the result of ergonomic and biomechanic studies and test done by Prologo in the last few years. With the ESD Prologo re-designs the transition area of the seating zone of the saddle with the following results: More space for the legs of the cyclist, plus much better pedal strokes(avoiding the sliding forward) equals the maintenance of the correct position.

Nack Tech
Nano carbon fiber rail. Carbon fiber, Kevlar and aluminum filaments seatpost clamp area, treated with the production porcess call Braided Carbon Rail(BDR). This is done in order to obtain "the perfect fusion" and uniformity of the serveral type of fiber and matierials. The result is a balance structure and resistant to penetration.
