Factor Sarana SRAM Force XPLR AXS Gravel Bike 2026
The Factor Sarana Gravel Bike is built for ultra-distance racing, self-supported exploration and demanding days beyond the tarmac. Its carbon frame combines endurance-focused geometry with responsive handling, helping riders maintain efficiency and control as the kilometres accumulate.
A leaf-spring seatstay system helps absorb rough-surface vibrations while preserving lateral stiffness, and generous clearance for tyres measuring up to 57 mm allows a wide range of gravel setups. Integrated downtube storage keeps essentials close at hand, while compatibility with a dropper seatpost and 30 mm travel suspension fork adds versatility for more challenging terrain.
Equipped with SRAM Force XPLR AXS 1×13 electronic shifting, a 10–46T cassette, Black Inc FORTY SIX gravel wheels and an integrated Black Inc cockpit, the Sarana brings race-focused performance to long-distance gravel riding.
FEATURES
Ultra-Distance Geometry: Carefully tuned stack, reach and steering geometry support sustained riding efficiency and confident control through fatigue.
Premium Carbon Frame: Toray and Nippon Graphite PAN-based carbon fibres form the foundation of a performance-focused gravel frameset.
Leaf-Spring Seatstays: Dropped seatstays and an offset seat tube allow controlled flex to reduce rough-road vibration while maintaining lateral stiffness.
Responsive Rear-End Geometry: Consistent 425 mm chainstays across all frame sizes help retain agile handling alongside generous tyre clearance.
SRAM Force XPLR AXS: Wireless electronic 1×13 shifting pairs with a 10–46T cassette for precise gear changes across varied gravel terrain.
Black Inc FORTY SIX Wheels: A 46 mm rim depth, 27 mm internal width and aerodynamic steel spokes balance speed and durability.
Generous Tyre Clearance: Clearance for tyres measuring up to 57 mm provides flexibility to prioritise traction and comfort.
Integrated Downtube Storage: A dedicated internal compartment with a custom bag provides space for tools, clothing and other ride essentials.
Gravel-Specific Cockpit: The Black Inc HB05 integrated barstem combines a short drop and wide flare for confident handling on demanding surfaces.
Dropper Seatpost Compatibility: The 30.9 mm seatpost interface and external clamp allow an optional compatible dropper post.
Suspension Fork Compatibility: Designed to accommodate an optional 30 mm travel suspension fork without compromising the intended geometry or handling.
Custom Frame Bag Options: Purpose-designed Post Carry bags offer additional carrying capacity for self-supported rides.
