Team Israeli startup "Nation" debuted Factor's new "Ostro" road bike at the Tour de France.

Factor's goal with this new frame was to combine the efficiency of an advanced aero package with the ruggedness of a bike that can roll over some pavé with ease.

For amateur riders, it became a true "quiver killer" road bike, with a wide range of capabilities that could theoretically replace a collection of two or three bikes.

The Ostro's overall aero shape is influenced by Factor's O2 Vam, with a similar down tube shape and geometry angles that are based on values proven on the brand's O2 frame.

On a size 54 frame, the new Ostro's seat angle is set at 73 degrees and the heat tube at 72.5 degrees. The geometry spectrum varies by size, and there are three different fork offsets to choose from, with a 53 mm carbon fork offset on the smallest size Ostro, 48 mm on the medium size, and 43 mm on the larger frame.

Besides Ostro's progressive geometry, the frame also incorporates compliance features. The bike's elegant, slim seatstays provide just the right amount of engineered flex to reduce road buzz, especially on imperfect surfaces.

Combining outstanding aerodynamics with high-capacity tire compatibility was a design challenge for this new bike. Factor's carbon fiber engineers solved this problem by controlling the entire process from concept to a series of iterations that eventually became Ostro.

Because Factor owns the carbon fiber production assets, the design engineers are not constrained by third-party suppliers. This allowed Ostro's product team to develop a frame that was extremely lightweight (780 g in size 54), but with perfect aerodynamic details.

One of Factor's Ostro's most notable aerodynamic design features is the generously spaced Caron fork construction. This wide leg spacing reduces the effects of wake turbulence caused by the rotating spokes, which disrupt the airflow through and around Ostro's forks.

Stagnant air and its potential drag is addressed by relief channels formed in the fork crowns to improve laminar airflow. This helps disperse the effects of dynamic air being forced upward by the rotation of the front wheel.

Ostro riders benefit from the reduced rolling resistance, better handling, more secure braking, and all-day comfort provided by the high-capacity tires. The bike can roll 26mm wide tubular or 32mm wide tubeless tires mounted on 21mm inside diameter rims.

Factor is offering the new Ostro with SRAM Red AXS for $10,099 (£9,250) and the SRAM AXS Force kit version for $8,199 (£7,850). Other models are available with Factor's new Black Ink Forty-Five carbon road bike wheelset.

It comes in three colors: Flicker, Soho Mix, and Sicilian Peach. Riders who prefer a customized finishing kit can opt for the $5,499 Ostro frame package, which includes a fork, seatpost, integrated bar stem, Ceramix Speed bottom bracket, and headset.
