The 3T Extrema Italia GRX Di2 Bike is 3T's most capable gravel machine — built for the longest days, the most technical terrain, and the kind of riding where a gravel race bike runs out of capability before you do. It sits at the extreme end of 3T's Italia lineup: above the RaceMax (mixed tarmac and gravel racing) and well above the Strada (road-focused), purpose-built around tire clearances and geometry that no pure race bike can match. With 57mm maximum tire clearance, a 10-51T cassette borrowed from Shimano's mountain bike catalog, and a fork rated to carry 3kg per side in cargo, the Extrema Italia is a drop-bar bike designed to go places where most drop-bar bikes stop.

Like the Strada Italia and RaceMax Italia, the Extrema Italia is handmade in Bergamo, Italy using 3T's proprietary filament-winding and RTM manufacturing process. Dry carbon fiber yarn is applied continuously through automated winding machines into heated resin-transfer molds — a process that gives 3T precise control over fiber angles, eliminates excess resin, and allows the frame's layup to be tuned specifically for the Extrema's demands rather than adapted from a road race template. The frame weighs 1,099 grams in size 54; the fork adds 420 grams. That fork — the 3T Fango Extrema Integrale — carries triple-bolt cage mounts on each leg, rated to 3kg of load per side, purpose-built for bikepacking accessories, front racks, and cage systems that keep mass forward and stable on loaded routes. The seatpost is a 27.2mm round section, which accepts wireless dropper posts — a fitment 3T explicitly recommends for the descents this bike can handle. The bike's "3Touring" geometry runs a relaxed 70.5° head angle and a 436mm chainstay in size 54, prioritizing long-day stability and all-day comfort over race-aggressive positioning.
Shimano GRX Di2 RX827 handles shifting wirelessly in 1x12 configuration. The rear derailleur pairs a 40-tooth chainring against a Shimano Deore XT 10-51T cassette — a gear range…
