Factor Ostro Vam Carbon Shimano Dura-Ace Di2 Road Bike

The Factor Ostro VAM Carbon is an aero road bike built for riders who want one bike to handle sprints, climbs, and rough pavement without switching machines. The frame is built from a blend of TeXtreme, Toray, and Nippon Graphite pitch-based carbon fiber, brought down to a 900g frame weight, and paired here with a Shimano Dura-Ace Di2 9200 groupset in a 2x12-speed, 52/36T crank and 11-34T cassette configuration. According to Factor, this generation is 250 grams lighter and 7 watts faster than its predecessor when built with the included Black Inc 48|58 wheels. The bike is positioned as competitive across terrain types — flat sprints, cobbled classics, and sustained climbs — rather than optimized for a single discipline. Internal cable routing is built for electronic shifting only, disc brakes run up to 160mm rotors front and rear, and the frame clears up to 32mm tires measured, giving riders room to move between smooth road surfaces and rougher pavement on the same bike. Who It's For Racers and serious club riders who want a single bike for varied terrain rather than separate aero and climbing bikes Riders committed to electronic shifting — this frame's internal routing doesn't support mechanical drivetrains Riders who want an aggressive fit: the integrated Black Inc barstem comes in an 80mm reach, 120mm drop Riders who need wider tire clearance than 32mm (gravel or rougher conditions) should look elsewhere What to Look For Bottom bracket compatibility: the CeramicSpeed T47A cups ship standard, with upgraded CeramicSpeed bearings available for DUB, 24mm, or Ultra-Torque cranks — confirm which matches your groupset Fit hardware: barstem, seatpost setback (0mm or 20mm), and saddle rail clamp size (7x7 or 7x9) all come in multiple configurations, so sizing should be confirmed before purchase Headset sizing: 1-1/8" upper and 1-3/8" lower, running CeramicSpeed SLT bearings Key Features The frame's carbon lay-up, combining TeXtreme, Toray, and Nippon Graphite pitch-based fiber, is what gets the frame to 900g while still targeting aero performance — a harder balance to strike than optimizing for weight or aerodynamics alone. The OSTRO Wide Stance Fork works with the Black Inc 48|58 wheelset, a deeper rear/shallower front combination aimed at aero gains without the handling penalties of matching deep-section wheels front and rear. The Dura-Ace Di2 9200 electronic groupset delivers precise, consistent shifting under load, which matters most on the climbs and sprints this bike is built for. Braking runs through discs sized up to 160mm front and rear, and 12mm thru-axles (100mm front, 142mm rear) are standard for the platform. CeramicSpeed bearings appear throughout — bottom bracket and headset — for reduced friction over the life of the bike. Rider Intent Summary Biggest strengths: low frame weight (900g) combined with aero wheels and an electronic-only Dura-Ace Di2 build Tradeoffs: 32mm max tire clearance and electronic-only routing limit this to road use with electronic drivetrains What makes it different: the Nippon Graphite pitch-based fiber lay-up and Wide Stance fork are engineered specifically for this frame, not shared generic components Victory's Take We see the Ostro VAM as one of the more genuine all-terrain race bikes we carry — light enough to matter on climbs, aero enough to matter on flats. At Victory Bicycle Studio, we'd want to confirm your bottom bracket standard and fit measurements before ordering, given how many build options this frame supports.
