gravel aero bike 3T Exploro RaceMax Rival AXS 2x Gravel Bike

The 3T Exploro RaceMax Rival AXS 2x Bike is the build that started the aero gravel category. 3T introduced the original Exploro in 2016 as the world's first aerodynamic gravel bike — a claim that reshaped how the industry thought about frame design for off-road riding. The RaceMax is the evolution of that platform, carrying forward the same aerodynamic engineering logic but applying 3T's more refined REALFAST methodology: engineering the frame's tube shapes specifically around the measured dimensions of the tires it's designed to run, not the label sizes. The result is a gravel bike built to be genuinely fast on the surfaces where most competitive gravel riding actually happens.

The RaceMax aerodynamic package is more precise than most aero gravel frames because it starts with a specific problem rather than general principles. The upper downtube is 50mm wide, shaped to intercept the turbulent airflow coming off the front wheel and redirect it smoothly around the frame. As it descends toward the bottom bracket, the downtube widens to 75mm — wide enough to completely shield a water bottle from the incoming airflow and maintain smooth boundary layer flow through the mid-frame. The headtube is dimensioned like a road bike: narrow externally, built around a 1-1/8" to 1-1/4" steerer, but hiding a 1-1/2" internal steerer for stiffness. 3T calls this the MinMax headset — it fits a big steerer inside a narrow external profile, which is the kind of engineering detail that looks obvious once you know what problem it solves. The rear wheel cutout is a close-fitting aero profile rather than the generous clearance cutout most gravel bikes use, which removes a significant aerodynamic penalty around the seat tube without sacrificing mud clearance.

The frame uses a unidirectional pre-preg carbon layup with a high-modulus/high-strength performance blend — the same material approach as the RaceMax Italia, though the Italia uses 3T's proprietary filament winding and RTM process for a different ride character. The pre-preg RaceMax is the race machine: bottom bracket stiffness is prioritized for power transfer, the geometry is aggressive and road-inspired, and the geometry program matches a road bike more closely than most gravel frames. Chainstay length is a consistent 415mm across all four sizes (51–58cm), which keeps rear-end handling predictable regardless of frame size. The fork is the 3T Fango RaceMax with a compact crown — 25mm shorter than a standard gravel fork, which tightens the front-end geometry and reduces the steering leverage a long fork creates on loose terrain.

The drivetrain is SRAM Rival AXS 2x12 — a fully wireless electronic groupset built around a 46/33 crankset and a 10-36 cassette. Two chainrings change the calculus versus a 1x setup: you get a tighter gear range across the cassette, which means smaller jumps between gears on sustained climbs and fast road sections, while the front derailleur shift handles the large range change. The combination suits a rider who races on mixed terrain at sustained tempo rather than someone who needs a bail-out low gear for loaded adventure riding. SRAM Rival AXS hydraulic disc brakes with 160mm rotors handle stopping front and rear. Wheels are Fulcrum Rapid Red 900 with 22mm internal width, tubeless-ready rims. The handlebar is 3T's Superergo PRO, a compact drop bar shaped for riders who spend time in the drops on fast descents and road transitions. The seatpost is the 3T Charlie Sqaero Team — an aero-profiled post with a Ritchey WCS clamp, maintaining the RaceMax's aerodynamic tube shapes through the cockpit.

This is a demo unit, offered at a significant reduction from the standard retail price. Demo bikes are inspected and represent a substantial value on one of the most aerodynamically engineered gravel frames available. The RaceMax is the choice for the rider who rides gravel competitively, commutes through headwinds, or simply wants a gravel bike that responds like a road frame without asking them to give up rough-road capability to get it.
