3T Exploro Ultra Graphite 56cm Carbon Gravel Frame 700c/650b

3T Exploro Ultra Graphite Carbon Gravel Bike Frame Only 56cm 700c/650b Disc

This listing is for a 3T Exploro Ultra carbon gravel frame in graphite finish. The Exploro Ultra is a high-performance gravel platform that blends aerodynamic design with wide tire clearance and modern geometry, making it capable on rough gravel, bikepacking routes, and fast mixed-surface rides.

Built from unidirectional high-modulus carbon fiber, this frame supports both 700c wheels with tires up to about 46 mm WAM (width as measured) and 650b wheels with tires up to approximately 61 mm WAM when set up with compatible components. It uses a BB386EVO press-fit bottom bracket standard for broad crank compatibility, flat-mount disc brake mounts, and internal cable routing for electronic or mechanical drivetrains.

This listing is frame only (no fork) and includes the seatpost wedge and derailleur hanger(s) needed to complete your custom build.
