Isaac Meson Ultegra Di2 road bike Mineral White is a race-focused aero road bike for riders looking for a blend of aerodynamics, low weight, and electronic shifting in the competition category. It’s built for fast road riding, racing, and performance training, where efficient power transfer, stability at high speed, and clean cable integration matter. The manufacturer states a weight from 7.7 kg, placing it among the lighter aero bikes in this class.
The foundation is a carbon composite frame Advanced Carbon Tech Triad 40, with the same material used for the fork—matching the focus on stiffness and low weight for a race platform. The frame is designed with integrated cable routing (Integrated Cable Routing System) and is complemented by the Isaac Airflow II cockpit, which hides the cables within the handlebar/stem area. The fork features a tapered steerer (1-1/8" to 1.5"), and the bike uses thru-axles 12×100 mm front and 12×142 mm rear. A key practical detail is tire clearance up to 32 mm, allowing you to choose fast race tires or a more comfortable setup for rougher asphalt.
The drivetrain is Shimano Ultegra Di2 2×12 with a rear derailleur RD-R8150 Di2 and front derailleur FD-R8150; the build uses Shimano Ultegra FC-R8100 cranks in 165 mm length with 52–36 chainrings. The Shimano CS-R8101 11–30 cassette provides a range suited to fast road riding and sporty climbs while maintaining tight gearing steps. Braking is handled by hydraulic disc brakes Shimano Ultegra BR-R8170 with levers ST-R8170 and Shimano RT-CL800 rotors in 160 mm front and 140 mm rear, with Center Lock mounting. The wheels are DT Swiss ARC1600 Spline DB with hooked (crochet) rims, a 55 mm depth, 22 mm internal width and 28 mm external; the manufacturer states tubeless compatibility. The cockpit is Isaac Airflow II Carbon (width 380 mm, reach 53 mm, drop 121 mm, flare 4°) with integrated bar tape, paired with a 90 mm carbon stem; the saddle is Surface Powerbox and the seatpost is carbon. The bottom bracket uses the T47 Inboard system (Token Zenith Premium Inboard, width 86.5 mm).
The aero road frame concept, combined with the 55 mm deep rims and fully integrated cable routing, targets low aerodynamic drag on flat roads and at high speed. The Advanced Carbon Tech Triad 40 carbon frame and fork, together with 12 mm thru-axles, support precise handling and stability under acceleration and through corners. Tire clearance up to 32 mm lets you increase comfort and traction by choosing wider tires without the bike straying from its road-focused intent. The combination of Ultegra disc brakes and 160/140 mm rotors increases control under braking, especially on descents and in poorer conditions.
Isaac Meson Ultegra Di2 is designed for performance-driven and racing road cyclists who want an aero platform with electronic shifting and modern disc brakes. It’s well suited to criteriums, fast group rides, races, and structured training where an integrated cockpit, deep-section wheels, and the option to run tires up to 32 mm make sense. Within the competitive landscape, it targets other UCI-approved aero road bikes with Ultegra Di2-level equipment.
