Factor Sarana SRAM Force XPLR 13.sp w. power meter
Factor Sarana – Cyan Blue
The Factor Sarana is developed specifically for ultra-distance gravel racing, where the demands on efficiency, control and durability are markedly different from those of a regular gravel bike. The frame was developed in collaboration with Rob Britton (winner of Unbound XL 2025) and tested over months of riding in British Columbia.
Frame
Carbon frame with a directional fiber layup – high-modulus carbon in the power-transfer zones (bottom bracket, chainstays) combined with intermediate-modulus layers for vibration damping. The seatstays are heavily dropped and shaped on a leaf-spring principle that absorbs vertical vibration without compromising lateral stiffness. 1x-only drivetrain, compatible with chainrings up to 52T. T47A bottom bracket. Flat-mount brakes, 160 mm native, max. 180 mm rotor. UDH derailleur hanger standard.
Tire clearance & fork
Up to 57 mm (2.2") tire clearance front and rear. The fork is prepared for both a rigid setup and a 30 mm-travel RockShox Rudy XPLR suspension fork, without any change to geometry or handling.
Seatpost
30.9 mm seat tube with external clamp – dropper post compatible.
Storage
Integrated down tube storage compartment with matching bag, plus a frame bag developed with Post Carry and designed around the frame's main tube profile for minimal drag.
