Noah Fast 3.0 Shimano Dura Ace DI2 2x12

The Noah Fast 3.0 is offered in four high-end drivetrain configurations: SRAM Red AXS, SRAM Force AXS, Shimano Ultegra Di2, and Shimano Dura-Ace Di2. That spread gives the frame a broad price ladder from premium race-ready builds up to flagship superbike territory, with the new-for-2025 Force AXS option likely serving as the key entry point into the full Noah Fast platform. Even without full pricing details, the range makes clear that Ridley is positioning this as a top-tier race chassis rather than an accessible aero bike.

The available build structure suggests Ridley is emphasizing drivetrain preference and tier rather than changing the bike’s underlying purpose. Arthur’s test bike used Ultegra Di2 with deep-section DT Swiss wheels, Vittoria Corsa tires in a 28 mm front / 30 mm rear combination, an SLR saddle, and Ridley’s own integrated cockpit, which gives a good sense of the intended spec direction: deep wheels, electronic shifting, and fully integrated aero packaging. The main practical distinction between builds will therefore be how much buyers want to spend for lighter weight and higher-end drivetrain hardware, rather than a change in the Noah Fast 3.0’s fundamentally race-specific character.

Reviewer David Arthur of Just Ride Bikes describes the Noah Fast 3.0 as a bike with a very narrow but very clear area of excellence. His main takeaway is that it comes alive at high speed, especially once the rider is in a deep aero position above roughly 45 km/h. In that context, he found it “quick, rapid, efficient, and comfy as well,” and notably said it was a position he could hold for hours. He was also surprised by how smooth the bike felt over rough roads given its extreme aero shaping, crediting some of that ride quality to the 28 mm front and 30 mm rear Vittoria Corsa tire setup run at lower pressures. He also notes that it posted the fastest lap time on his test track, reinforcing the impression that the bike does what it is designed to do.

The downside, in Arthur’s view, is that the Noah Fast 3.0 is much less appealing outside that race-speed envelope. He repeatedly characterizes the steering as very slow and says the bike feels dull, heavy, and unresponsive at more typical riding speeds around 25–30 km/h. The quoted 8.2 kg weight of the Ultegra Di2 test bike was a recurring criticism, particularly on climbs and twistier roads where he felt it lacked the agility and liveliness of more rounded performance bikes. He also questioned the value of the £8,000 Ultegra Di2 build, noting the absence of a power meter and only minor refinement issues such as a less-than-ideal computer mount. Overall, the review paints the Noah Fast 3.0 as a highly effective but highly specialized aero race tool: excellent for riders who genuinely ride fast, less convincing for those wanting an all-purpose superbike.
