Description
Factor Sarana Red XPLR Gravel Bike
Engineered for ultimate speed, compliance, and all-day endurance, the Factor Sarana Red XPLR Gravel Bike combines cutting-edge carbon technology with premium components. Crafted from Toray and Nippon Graphite pan-based fibres, the monocoque frame delivers exceptionally responsive handling and power transfer while absorbing harsh trail feedback. The front end features a 1.5-inch integrated headset with clean internal cable routing and a sleek Black Inc integrated barstem, ensuring an aerodynamic profile without sacrificing control. Designed around modern 700c gravel geometry, this build runs on CeramicSpeed T47A WIDE bottom bracket bearings for maximum drivetrain efficiency and offers massive tyre clearance up to 57 millimetres to conquer the most challenging terrain.
Shifting and Braking Performance
At the heart of this high-performance setup is the wireless SRAM RED E1 XPLR 1x13-speed electronic groupset, paired with a 44-tooth crankset and a wide-range 10 to 46-tooth cassette for precise gearing across steep climbs and fast flats. Powerful hydraulic disc brakes with 160 millimetre rotors front and rear provide consistent stopping power in all weather conditions, while 12 millimetre thru-axles ensure total frame rigidity under heavy cornering. The lightweight Black Inc 46 wheelset complements the drivetrain seamlessly, delivering sharp acceleration, stability in crosswinds, and effortless momentum over unpredictable surfaces.
Integrated Storage and Bike Build Features
Designed for gravel racing and remote adventure, this complete build comes equipped with custom frame accessories including a dedicated downtube storage bag, top tube pack, and frame pack. A lightweight FSA SL-K seatpost offers subtle vibration dampening at the rear, while the frame remains fully compatible with 30.9 millimetre dropper posts for steep, technical descents. Backed by Factor's limited lifetime warranty, this 13-speed gravel machine represents a race-ready package designed for uncompromising speed, comfort, and reliability across any course.
