Product Description
2026 FACTOR OSTRO GRAVEL FRAMESET
The Ultimate Foundation for High-Speed Off-Road Racing.
Redefining dirt-road velocity where aerodynamics meet high-volume traction, the 2026 Factor OSTRO Gravel Frameset turns wide-open fire roads and technical hardpack into high-speed timed trials. Marrying wind-cheating tube profiles with brutal torsional rigidity, this gravel-racing thoroughbred slashes drag through high-speed winds while absorbing trail chatter so you can drop the hammer long after the tarmac ends.
Pro-Tier Build Highlights
OSTRO Wide-Stance Aero Gravel Fork: Specialized broad-blade fork geometry engineered to cleanly manage turbulent boundary-layer airflow around high-volume gravel rubber.
Tri-Fiber Composite Skeleton: High-modulus matrix fusing TeXtreme®, Toray®, and Nippon Graphite® fibers for max lateral sprint efficiency and fatigue-filtering compliance.
CeramicSpeed Bearing Suite: Factory-fitted SLT 1.5-inch headset and threaded T47A bottom bracket architecture delivering zero-maintenance rotational longevity.
True 45mm Tire Envelope: Generous clearance engineered to swallow high-volume mixed-surface rubber for lower impedance and unshakeable cornering bite.
Digital-First Stealth Routing: Clean monocoque-integrated internal line architecture dedicated exclusively to wire-free or clean electronic group setups.
