Combining the Dimension family's compact V-shape profile with increased cushioning, enhanced grip, and vibration-damping Tirox rails, the R2 AGX delivers the support and stability needed when fast riding moves beyond smooth pavement. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAGX Performance — Engineered for Rougher Roads\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAGX stands for Adventure, Gravel and Cyclocross — Prologo's saddle platform developed to balance race-level efficiency with the additional comfort required on broken pavement, gravel roads, and extended off-road rides.\u003c\/p\u003e\n\u003cp\u003eCompared with road-focused designs, the Dimension R2 AGX uses a more compliant base and additional next-generation foam to better absorb vibrations and impacts without sacrificing the support required for efficient power transfer. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eV-Shape Ergonomics for a Stable, Forward Riding Position\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Dimension R2 AGX features Prologo's characteristic V-shaped geometry with a flat profile and an advanced anatomical center. This design helps reduce unnecessary movement on the saddle and encourages a stable, slightly more forward position — ideal for riders with good pelvic flexibility and an aggressive riding style.\u003c\/p\u003e\n\u003cp\u003eA redesigned 40 mm-wide nose provides additional support when moving forward during hard accelerations, steep climbs, or high-power efforts, while its rounded profile improves comfort in more dynamic riding positions. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3D Slide Control — More Grip When the Terrain Gets Loose\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrologo's 3D Slide Control surface technology is designed to increase grip between the rider and saddle. The textured upper helps maintain a consistent position when riding across uneven gravel, technical terrain, or repeated accelerations — reducing unwanted sliding while allowing the rider to remain properly supported through the pedal stroke. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePAS Pressure Relief for Long-Distance Comfort\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the center of the saddle, Prologo's PAS (Perineal Area System) uses an open central channel to reduce pressure peaks and compression in sensitive areas. By helping relieve soft-tissue pressure and improve comfort around the pelvic zone, the PAS design is particularly valuable during long gravel rides where changing surfaces and sustained seated efforts can amplify discomfort. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTirox Rails — Performance with Added Vibration Absorption\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis version of the Dimension R2 AGX uses Prologo's Tirox rail system, manufactured from lightweight alloy steel. Tirox provides an excellent balance of strength, stiffness, weight, and vibration absorption — making it especially well suited to gravel and all-road applications.\u003c\/p\u003e\n\u003cp\u003eThe Tirox version is paired with an injected-carbon base engineered to maintain efficient support while offering the compliance needed for rougher terrain. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo Widths.
