PROLOGO Scratch Pro Tirox Saddle & Onetouch Bart The Scratch Pro Tirox borrows a fairly traditional, round profile. This makes it absolutely ideal for riders who tend to stay seated, even for climbs. Its shape, materials, & rail system have all been engineered to provide one of the lightest & most supportive saddles available, making it ideal for both road & XC mountain applications. Prologo chose to build the Scratch Pro Tirox Saddle around its Tirox rail system. This is a light steel rail with a base & clamping zone that are both durable & incredibly stiff — it's the same composition used in the airspace industries due to its low weight & durable properties. Prologo then attached its carbon fiber injected "skeleton" base to the Tirox rails, creating a supportive foundation that works in conjunction with its multi-density padding.
