Isaac Meson 105 Di2 road bike Ruby Red is an aero race road bike built for fast riding on asphalt, based on a carbon frame with integrated cable routing and disc brakes. It targets experienced riders looking for a combination of aerodynamics, low weight, and precise electronic shifting in the race-bike segment with Shimano 105 Di2 equipment. The 2026 model year specification follows modern standards (12-speed drivetrain, thru-axles, tubeless-ready wheels).
Both the frame and fork are made from the Advanced Carbon Tech Triad 40 carbon composite, designed for aero road use and high torsional stiffness around the bottom bracket and head tube area. Cable routing is fully integrated (Integrated Cable Routing System) and interfaces with the Isaac cockpit, reducing exposed routing at the headset. The Token A-Box headset uses IS52/28.6 | IS52/40 (45°) bearings, and the fork features a tapered 1-1/8"–1.5" steerer. The frame is designed for 12×100 mm front and 12×142 mm rear thru-axles, and the manufacturer states a maximum tire clearance of 32 mm.
The drivetrain is the electronic Shimano 105 Di2 2×12 group with a Shimano 105 RD-R7150 Di2 rear derailleur and Shimano 105 FD-R7150 front derailleur, paired with Shimano 105 FC-R7100 cranks (170 mm) with 52–36 chainrings. Gearing for fast road riding and sporty climbs is provided by a Shimano CS-R7101 11–30T cassette; the chain is Shimano CN-M7100. The braking system is hydraulic: Shimano 105 ST-R7170 levers and Shimano 105 BR-R7170 calipers with Shimano RT-CL800 rotors sized 160 mm front and 140 mm rear, Center Lock mounting. The DT Swiss ARC1600 Spline DB wheelset uses Hooked (tubeless-ready) rims with a 55 mm depth and 22 mm internal width, fitted with Goodyear Eagle 700×30C tires. The cockpit consists of Isaac Airflow II Carbon carbon handlebars (380 mm, reach 53 mm, drop 121 mm) and a 100 mm carbon stem with a -5.5° angle; the saddle is Surface Powerbox 244×148 mm and the seatpost is carbon with 0 mm setback.
The combination of an aero frame, tall 55 mm rims, and an integrated cockpit results in a focus on speed on the flats and maintaining pace in the wind, where a clean front end and a stable wheel platform matter. The carbon frame with 12×100/12×142 mm thru-axles supports precise cornering lines and predictable behavior under disc braking. The fitted 700×30C tires and clearance up to 32 mm make it possible to set pressure for real-world surfaces and improve control and comfort without moving away from a road-focused setup. The 52–36 gearing and 11–30T cassette suit sporty road use, with an emphasis on fast sections and efficient cadence on gentle to moderate climbs.
Isaac Meson 105 Di2 is designed for experienced road riders and race-oriented recreational cyclists who prefer aero geometry and electronic shifting in the price range of bikes specified with Shimano 105 Di2. It makes sense for fast training rides, criteriums, amateur races, and long rides at higher intensities, where you’ll appreciate the combination of an aero wheelset, disc brakes, and the modern T47 bottom bracket standard.
