Product Details
The 3T Racemax Boost Italia Rival XPLR AXS 1x12 takes the speed and efficiency of the original Racemax and adds seamless electric assist—perfect for pushing your off-road and all-road adventures even farther. Built in Italy using filament winding and RTM carbon molding, this limited-edition model combines performance, precision, and heritage with a custom colorway that nods to 3T’s racing legacy.
At the heart of the bike is the Mahle X20 system, delivering a smooth, natural boost with 55Nm of torque and a lightweight 236Wh battery. The bike’s weight stays impressively low—around 12kg—giving you all the benefits of e-assist without the bulk. You’ll ride with confidence knowing the SRAM Rival XPLR AXS 1x12 drivetrain offers wireless shifting that’s crisp, clean, and reliable across varying terrain. Matched with 3T Discus 45|40 carbon wheels, the Boost Italia is built for riders who want it all—speed, traction, and style.
Designed with REALFAST aero shaping and the 3T MORE Integrale cockpit, the Boost Italia hides cables internally without compromising on fit or maintenance. It’s everything you want in a fast gravel e-bike—with nothing holding you back.
