3 FLAVORS OF EXPLORING
The PRIMO bikes all use the latest generation of the original Exploro frame. It’s a great choice for a high-end, highly-versatile gravel bike at an affordable price.
The RACEMAX and RACEMAX ITALIA are the absolute fastest gravel bikes possible, aero optimized for for 35-42mm WAM (Width As Measured) tires but for particularly tough rides or long trips it even fits up to 61mm tires.
The ULTRA and the EXTREMA ITALIA are designed to go fast on the worst possible terrain, aero optimized for 55-61mm tires (but of course you can spec a narrower tire too). They also combine an aero seattube with a round seatpost so you can use any 27.2 round, dropper or suspension post.
