3T Ultra2 Italia GRX 1x12

The most accessible way into a complete 3T Made in Italy bike, the Ultra² Italia GRX 1x12 combines advanced Italian carbon construction with the proven reliability and simplicity of Shimano mechanical shifting.

At its core is the Ultra² Italia Fusion Carbon frame, manufactured using a hybrid process that combines 3T’s proprietary filament winding and Resin Transfer Moulding (RTM) technologies with selected elements of traditional carbon manufacturing.

The mechanical Shimano GRX 1x12 drivetrain delivers dependable, straightforward shifting with a wide 10–51T cassette, giving you the range to tackle steep climbs, rough gravel and varied terrain without the complexity of a front derailleur.

Finished with a Fulcrum Lite GR wheelset, 3T Superghiaia Integrale LTD cockpit and Fizik Vento Argo X5 saddle, the Ultra² Italia GRX 1x12 is built for riders looking for a versatile, performance-focused gravel bike with genuine Made in Italy pedigree.
