Prologo Nago R4 3D PAS Tirox Saddle Black, 245x137mm

What Our Gearhead(R) Experts Are Saying:"This saddle felt broken-in from the first ride. The 3D-printed zones really do change how it supports you across climbs and longer efforts, and the Tirox rails absorb trail buzz better than expected. It's supportive without being harsh."We roll into hard training days and weekend routes with the Nago R4 3D PAS Tirox Saddle giving us an adaptable platform tuned for mixed terrain. Its semi-round T-shape lets us shift naturally between climbing, steady flats, and long descents, while the open PAS channel relieves pressure where we feel it most on long hours in the saddle. The 3D-printed padding blends mapped densities that flex and support in the right places as we settle in for extended climbs. Back-road chatter softens through the Tirox alloy rails, and the carbon-reinforced base keeps power transfer crisp without feeling too stiff. From day-in, day-out training to big mileage weekends, this saddle maintains a smooth, supportive feel that helps us stay focused on the ride-not the pressure points.
