Developed and designed to be the best bikes in the world, Factor bikes give riders the freedom to go fast and have fun. With total control over every aspect of the design, development and manufacturing process, we at Factor know that our expanding range will enhance outings on any terrain. So, where do you ride next?

Speed is your goal. Every ride, whatever the surface, faster is what counts, and this is the gravel bike you've been waiting for. The OSTRO Gravel draws its "win everywhere" mentality from its stable road racing companion, the OSTRO VAM, and is also developed to dominate its class with incredible aerodynamics, superior handling, high stiffness and low weight. With a tire capacity of 45 mm, it's ready to go anywhere, fast.

Many off-road and gravel bikes struggle to offer efficient, confident steering both on and off-road, usually ending up with an unsatisfactory compromise of smooth handling and modest tire capacity. The OSTRO Gravel breaks this mold by making tire size an integral part of the geometry. Wider Tires tires also have a larger outside diameter (or rolling circumference), which increases the actual or "resultant" track of a bike; narrower Tires tires have a smaller outside diameter, which reduces resultant drag. These results correspond to the handling response you want when riding these respective Tires , so we designed the resulting track as a priority. We selected a track value on the slightly faster handling side for gravel use, given the bike's racing orientation, while prioritizing head tube angle when selecting our fork rake. This results in a gravel bike with fast handling on Tires 43mm and an equally satisfying and precise off-road machine on 32mm.

The new Black Inc THIRTY FOUR wheels are - like the OSTRO Gravel itself - dedicated to speed on gravel. Their 34 mm depth maximizes aerodynamic gains while keeping weight to a minimum and avoiding a too-high rim and tire lateral zone, ensuring crosswind stability. They are more aerodynamic with a 32 mm tire for off-road use, but also very efficient for Tires gravel up to 43 mm. The 25 mm internal width allows larger Tires tires to take better shape. The hookless rim is designed to facilitate the mounting of Tires tubeless, in most cases with an ordinary foot pump. The rim features a secondary shoulder that holds the tire securely in place in the event of rapid deflation, allowing you to stop in a controlled manner. Black Inc hubs run on CeramicSpeed bearings for ultimate efficiency.
