The 2024 3T Exploro RaceMax Boost GRX blends aero gravel performance with electric assist, delivering a fast, fluid ride across mixed terrain. Its carbon frame mirrors the aero-tuned geometry of the RaceMax, but adds Mahle’s X20 hub-drive motor system for subtle, efficient pedal support when you need it most. Outfitted with Shimano GRX drivetrain components, it maintains the mechanical simplicity and rugged reliability gravel riders expect. With clearance for wide tires and a stealthy battery integration, the RaceMax Boost is built for riders who want to go farther, faster—without giving up the feel of a real gravel bike.
