The 3T RaceMax Integrale GRX Di2 Bike is built on a single premise: gravel doesn't have to be slow. Where most gravel bikes accept aerodynamic compromise as the cost of off-road capability, 3T's RaceMax platform was designed from the start to minimize that tradeoff. The result is a carbon gravel bike that handles dirt roads and mixed terrain without abandoning the aero engineering that makes meaningful differences on long, fast rides.

Realfast Frame Design
The frame is shaped around 3T's Realfast methodology, which uses actual tire measurements — Width As Measured (WAM) and Radius As Measured (RAM) — to define the aerodynamic envelope around the tire rather than leaving an arbitrary gap. For 700c tires, the RaceMax Integrale accommodates a WAM of 35–46mm; swap to 650b wheels and that opens to 61mm WAM, wide enough for a completely different character on more demanding surfaces. The lower downtube runs 75mm wide specifically to wrap around a mounted water bottle, reducing airflow disruption from the bottle itself. The upper downtube narrows to 50mm where it meets the head tube, managing air from the front wheel before it reaches the down tube. The fork uses a compact crown — road-length rather than the taller crowns common on gravel bikes — which keeps handling precise and reduces weight. Double-drop chainstays create tire clearance while maintaining lateral stiffness, and the threaded bottom bracket shell provides more reliable interface alignment than a press-fit under real-world conditions. Chainstay length is 418mm across all six sizes, keeping the rear end consistent regardless of frame size.
Integrale Cockpit System
The "Integrale" designation refers to the fully integrated cockpit, where cables and hoses route internally through the stem and handlebar rather than running externally. This isn't just aesthetic — internal routing eliminates the aerodynamic drag of exposed cables at the front of the bike, which is one of the more significant sources of resistance…
