Factor Ostro Vam Carbon Shimano Ultegra Di2 Road Bike

The Factor Ostro Vam Carbon Shimano Ultegra Di2 Road Bike is an all-around race bike built to close the gap between climbing bikes and aero bikes rather than force a choice between the two. Factor's in-house carbon lay-up blends TeXtreme, Toray, and Nippon Graphite pitch-based fiber into a frame that comes in at a claimed 900 grams, paired here with a Shimano Ultegra Di2 8100 electronic groupset and full disc brakes. This generation of the Ostro Vam is 250 grams lighter and 7 watts more efficient than its predecessor, gains Factor attributes to the redesigned OSTRO Wide Stance Fork and the switch to Black Inc 48|58 wheels, a depth-optimized aero wheelset built specifically for this frame. The result is a bike suited to flat sprints, cobbled classics, and sustained climbs alike. Who It's For ● Racers and club riders who want one bike for climbing days and flat, high-speed stages ● Riders who prioritize a low frame weight (900g) but don't want to give up aero wheels ● Riders committed to electronic shifting, since routing is not set up for mechanical groupsets ● Riders who want a race-ready build out of the box: Ultegra Di2 8100, CeramicSpeed bearings, and Black Inc wheels and cockpit all come standard What to Look For ● Cockpit fit: the Black Inc Integrated Aero Barstem has an 80mm reach and 120mm drop; confirm this shape works for you, even with multiple stem lengths and bar widths available ● Bottom bracket and crank compatibility: CeramicSpeed T47A aluminum cups accept DUB, 24mm, and Ultra-Torque cranksets ● Tire clearance: 32mm measured is generous for a race bike but is a road-and-light-cobble limit, not a gravel one Key Features Frame and fork: the TeXtreme, Toray, and Nippon Graphite pitch-based carbon lay-up is engineered in Factor's own factory, and the OSTRO Wide Stance Fork is part of what Factor credits for this generation's weight and aero gains. Groupset: Shimano Ultegra Di2 8100 runs 2x12-speed electronic shifting with a 52/36T crank and 11-34T cassette, enough range for sustained climbs without sacrificing top-end gearing. Internal, electronic-only cable routing keeps the front end clean. Brakes and wheels: disc brakes accept up to 160mm rotors front and rear, with 160/140mm rotors included. The Black Inc 48|58 wheelset is depth-optimized front-to-rear for aero performance, and 12x100mm front / 12x142mm rear thru-axles secure everything. Bearings and finishing kit: CeramicSpeed SLT bearings run in the headset (1-1/8" upper, 1-3/8" lower), with CeramicSpeed T47A bearings available for the bottom bracket. Black Inc Aero Integrated Bottle Cages are included, and the frame carries a Limited Lifetime Warranty. Rider Intent Summary ● Biggest strength: a 900g frame combined with the aero-optimized Black Inc 48|58 wheels, a claimed 250g weight savings and 7-watt aero improvement over the previous Ostro Vam ● Tradeoff: 32mm max tire clearance and electronic-only compatibility narrow this to road and light-cobble riding on a dedicated Di2 build ● What makes it different: a frame designed to compete on climbs and flats alike rather than specializing in one Victory's Take We think the Ostro Vam earns its place as a genuine one-bike quiver for riders who race varied terrain: the weight and aero numbers show up in how it carries speed uphill and down. At Victory Bicycle Studio, we'd recommend a professional fit session given the fixed cockpit geometry, to confirm reach and drop match your position before you buy.
