Factor has launched its latest gravel bike called the Ostro Gravel, which seeks to blur the lines between the tarmac and the road less traveled with a more aggressive geometry and a sleeker aerodynamic signature than what’s typically found on most gravel grinders.
Utilizing a blend of TeXtreme and Toray carbon that’s interwoven with Nippon Graphite fibers, the Ostro Gravel comprises both ovalized and truncated tube profiles, which not only enhances the frame’s wind cheating capabilities, but also allows it to tip the scales at an impressive 900 grams.
Elsewhere, the Ostro Gravel is treated to full internal cable routing thanks to Factor’s new Black Inc HB02 combination carbon bar and stem, allowing the hydraulic brake hose to pass through the handlebar and stem down the front of the headset through a split ring. From there, it runs down the down tube or the fork leg.
Additionally, since the Ostro Gravel’s fork uses a rounded 1 1/8in steerer, riders can ditch the HB02 set-up in favor of a third-party cockpit, while a T47A threaded bottom bracket with CeramicSpeed bearings ensures a smooth and solid bottom bracket interface.
What about tire clearance?
Factor says the new Ostro Gravel can accommodate tires up to 43mm.
In order to ensure that the rubber meets the road properly, Factor offers customers a frameset and wheelset bundle courtesy of its Black Inc Thirty-Four carbon wheels, which feature 34mm hookless rims that spin on the brand’s own hubs with CeramicSpeed bearings.
For those wanting a complete bike, Factor offers the Ostro Gravel in a number of builds that start at $8,600.
