Sizing Guide

The chart below provides a general recommendation for bike sizes based on height, though keep in mind that sizing can vary between different brands and type of bike. If you have specific fit concerns regarding this bike, don’t hesitate to contact us!

Getting the right fit on a bike is essential for both comfort and performance, and it may take a little time to adjust to a new setup. You can easily modify key components, like the pedals, saddle, and shoes, to better match your riding style and comfort preferences.

While the chart helps suggest an appropriate size based on your height, other measurements like your torso length and inseam are also important for a perfect fit. We recommend visiting a store for a professional fitting to ensure you find the best size for your needs. All bike purchases picked up in store come with a complementary comprehensive bike fit to ensure you’re comfortable on your new ride.

Under 5’6” Under 173cm 48cm
5’6” - 5’8” 167 - 173cm 51cm
5’8” - 5’10” 173 - 178cm 54cm

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.

GRAVELPLUS: FIT ROAD, GRAVEL & MTB TIRES

The Exploro Primo 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. For 700c, we recommend our 3T Discus wheels, for 650b our 3T DiscusPlus wheels.

REALFAST

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).
  • The Exploro is also a great road bike in its own right. When using it for fast paved (group) rides, any aero benefit is appreciated.

We didn’t want the Exploro Primo 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).

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.

DESIGN IS IN THE DETAILS

CLEAN PERFORMANCE: Internal cables, hoses and seatpost clamp clean up the frame aerodynamically and visually. Dedicated FlipTop cable guides are future-proof with in mechanical & electronic versions for single & double chainrings.

HANG LOOSE HANGER: Mounting a rear wheel with disc brake can be a pain, we make it easy. Forget the derailleur, focus on the disc, put the wheel in, slide thru the axle and hang the derailleur back with the wheel already securely in place.

SEATPOST EXPANDER: The original Exploro Primo has a beautiful hidden expander, but a top-mounted expander is a bit more user-friendly so just like on the Strada, we now offer this design on the Exploro.
