EXPLORO PRIMO : THE WORLD’S FIRST FULL-AERO GRAVEL BIKE
The Exploro Primo has changed gravel riding & racing forever, combining road speed and mountain toughness.
Fast on any surface; paved, gravel and singletrack. Winner of Unbound, Jeroboam, RAT1000, etc.
SQAERO
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 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.
We also use Sqaero on the headtube, seattube, seatstays and seatpost.
