3T Exploro Pro GRX
All-road riding is an adventure for the mind as much as the body and the 3T Exploro Pro GRX is the perfect vehicle for roads ranging from dirt, to gravel to pavement and anywhere in between.
With superb tire clearance, an incredible frame and geometry built for speed and a sweet SRAM GRX drivetrain, the 3T Exploro Pro GRX will take you down roads and paths less traveled in record time.
The key to the 3T Exploro’s speed is the aero downtube that is wide enough to catch the airflow coming off the big front tire (a skinny downtube wouldn’t even touch the airflow). But at 50mm wide, a full airfoil with a normal ratio would have to be 150-200mm deep, causing too much surface drag. So we square off the tail, keeping most of the aero performance with a 50x75mm cross section that is also close to perfect for strength and stiffness; our Sqaero shape. The wide downtube also effectively shields the water bottles.
3T also use Sqaero on the headtube, seattube, seatstays and seatpost.
3T didn’t want the Exploro to be fast in theory, but in the real world. So we tested at a realistic 20mph (32kmh) instead of the standard 30mph (48kmh) and optimized the frame for water bottles (tough to do long, epic rides without). We even designed the Sqaero shape to work well when covered in mud! The result? A muddy Exploro with 40mm knobby gravel tires and 2 water bottles (red line in the graph) is faster than the equivalent clean round tube bike is with 28mm slick road tires and without bottles (grey line).
