3T Exploro Primo - Campagnolo Ekar
13-speed Campagnolo drivetrain for perfect gearing on- and off-road at the best price-quality ratio.
The key to the 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 3T squared off the tail, keeping most of the aero performance with a 50x75mm cross section that is also close to perfect for strength and stiffness; 3T’s Sqaero shape. The wide downtube also effectively shields the water bottles.
