There is something magical and fun about riding on a mixture of surfaces, and only the EXPLORO delivers on all terrains. Its road geometry is fast on good surfaces and capable on bad ones. Its clearance for up to 2.1” mountain bike tires means nothing will stop you. And the aerodynamics are so good that even with knobby tires, it outperforms round-tube road bikes with skinny tires. There’s simply nothing else like it. The Exploro is designed to fit road, cross and even mountain bike tires following the GravelPlus standard. The road and cross tires are 700c, the mountain bike tires use the 650b size, ensuring that all of these have virtually the same overall wheel diameter and therefore the same predictable handling. Why is aerodynamics important on allroad (asphalt, gravel, fire roads, single track) rides? - You may go slow off-road, but on the connecting asphalt sections, you need road riding speed. - If you’re slow because of gradients, aero doesn’t matter much. But if it's due to head- or crosswinds, you're slow relative to the ground but very fast relative to the air, and that’s what determines the resistance you experience (that’s exactly why you’re slow). We didn’t want the Exploro to be fast in theory, but fast 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 is faster than the equivalent clean round tube bike is with 28mm slick road tires and without bottles. 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.
A stiff frame for ultimate power transfer. Wider tires for an unexpected wealth of comfort. A 1x drivetrain to improve aerodynamics and save 400g in component weight. And aerodynamics optimized around all these features! The Strada blends together benefits in a way no other aero road bike can. Do you want speed or comfort? Both! Wider tires are one of the biggest factors in road bike comfort by reducing the shock of cracks, curbs, and cobbles. But aerodynamics are also important on such rides, and wide tires tend to test poorly in the wind tunnel. However, that is to be expected if you test them with frames and parts optimized for narrow tires. The Strada is the first aero road frame optimized for wider tires, so finally you can be fast and comfortable all the time, from the cobbles to the climbs. All day, every day, with one and the same bike. With all aero road bike developments of the past 20 years, the drivetrain was never really tackled. So we did. The BB area - with frame, crank, chainrings, front derailleur, water bottles and rider legs - leaves little room for the air to pass through. A single ring drivetrain eliminates the front derailleur and inner ring. Thus it reduces frontal area and creates space for unobstructed air flow. And with modern cassettes (in particular the 3T Overdrive and Bailout), you still have all the gears you need.
