Description The OSTRO Gravel V.A.M. Frameset by Factor – Carbon racing machine par excellence The OSTRO Gravel V.A.M. frameset from Factor is the further development of the high-performance road bike frame into a race-oriented frameset for gravel biking and more. In this aerodynamic carbon frame and the equally streamlined carbon fork, there is room for up to 45 mm wide 28-inch tyres, making even difficult gravel passages a cinch. The integrated, wind-optimised seatpost blends stylishly into the overall concept. High-end headset and bottom bracket from CeramicSpeed minimise friction losses during the ride. Thanks to the wind-optimised handlebar stem unit from Black Inc, the frameset lives up to its name – OSTRO is one of the main Mediterranean winds. On the underside of the handlebars, there is a mounting option for the included bike computer mount. Designed for fully-integrated cable routing for electric groupsets, you can decide yourself whether you want to use one or two chainrings. You can quickly replace the front derailleur mount if you only want to use one chainring. This gives you a smooth seat tube without protruding braze-on attachment. Eyelets for bottle cages or bags are located on the down tube, seat tube and top tube. To demonstrate the frameset’s ability to withstand the most adverse conditions, Factor has already sent OSTRO Gravel V.A.M. builds into the race at the Unbound Gravel 2022, where they passed the endurance test with flying colours. Factor also stays true to the principle of ” One Bike for All” with the OSTRO Gravel V.A.M. frameset. That’s why you can ride fast with 28-inch wheels or 650B wheels or with a narrow road chassis. Whether it’s a speedy gravel bike or super-aerodynamic road bike, the choice is yours.
