The 3T eExtrema Italia is the electric version of 3T’s Extrema gravel platform, built around the same made-in-Italy frame concept rather than a visibly separate e-bike chassis. Its defining feature is how closely it preserves the silhouette and intent of the non-assisted bike while integrating a Mahle X20 hub motor and 350Wh iX350 battery. This is not an e-gravel bike built around oversized tubing or compromised tire room: it keeps the Extrema’s broad off-road remit with clearance for 700x57c tires, double-drop chainstays, a threaded bottom bracket, UDH compatibility, and direct-mount 160mm brake interfaces.
In the market, it sits at the premium end of the lightweight, stealth-assist gravel category. Compared with racier electric gravel bikes, the eExtrema Italia leans more toward rough-surface versatility and load-carrying practicality, with slightly more upright geometry than 3T’s eRacemax, fork cargo mounts, and a 27.2mm round seatpost that can take a wireless dropper. The full MORE internal routing and Integrale cockpit keep the bike visually clean, but the platform’s real distinction is that it combines aero-influenced 3T design with unusually large tire clearance and integrated electric assist without abandoning serviceable standards like a threaded BB.

Geometry & fit.
4 sizes published.
The eExtrema Italia’s geometry points to a stable, all-terrain gravel bike rather than a sharp, race-first setup. Across the size range, the 437mm chainstays are relatively long for gravel, and wheelbases run from 1036mm in M to 1050mm in XL, with the S actually stretching to 1044mm because of its notably slack 69.1-degree head angle. Those numbers suggest calm steering, good composure on rough descents, and room to run the bike with very large tires without making the handling nervous. Bottom bracket drop is also generous at 76mm in M and L, 79mm in S, and 74mm in XL, which should help keep the rider planted and lower the center of gravity.
Fit-wise, the bike trends a bit more upright than an aggressive gravel race bike. In size M, the 570mm stack and 368mm reach indicate a balanced, less stretched position, while the consistent 73.5-degree seat angle keeps pedaling position neutral across the range. The front-end geometry varies meaningfully by size, with the smaller sizes getting slacker head angles to maintain stability, while the XL steepens to 72 degrees for a more proportionate steering feel. Overall, the numbers support 3T’s positioning of the platform as a high-speed gravel bike that is still meant to stay composed when the terrain gets rough and the tires get big.

The lineup.
2 builds, ranging $10,999 – $13,999.
The current range is concise and clearly premium, with two builds: Rival XPLR AXS 1x13 DB Discus 45|40 at $10,999 and Red XPLR AXS 1x13 DB Discus 45|40 at $13,999. Both sit on the same made-in-Italy eExtrema platform with the Mahle X20 system, so the main distinction is component level rather than frame or motor hardware. That makes the lineup easy to understand: buyers are choosing between a lower-priced electronic drivetrain build and a flagship execution of the same concept.
The Rival XPLR AXS model is the more rational value entry into the platform, delivering the same frame, integrated layout, and wheel/tire format without the premium attached to SRAM’s top-tier group. The Red XPLR AXS version is aimed at riders who want the lightest and most refined drivetrain package available in the range. With both builds specified around 1x13 XPLR AXS and Discus 45|40 wheels, 3T is keeping the equipment focus tightly aligned with modern performance gravel use rather than offering a wide spread of price points or alternative personalities.
