IAx Advanced Ultegra Di2

It's tuned to feel quick when you push the speed. For road riding, the score leans toward outright pace rather than comfort-first priorities. The strongest influences are narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, a solid drivetrain that supports efficient riding, and a relaxed posture that gives up some aero efficiency.

How it climbs: 1.8/10. Within Road bikes, this comes out near the bottom. On climbs, the lowest gear feels tall. In numbers, the low gear is roughly 32.4 gear inches. In its peer group, it lands around the easier ~18% for low-gear climbing. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. Expect more grinding on climbs than easy spinning. Real-world feel depends on setup and size, and some details aren’t always listed, so this is best seen as a well-informed estimate.

For a triathlon build, aero-wise, at 10.0/10, it’s designed around going fast in exposed conditions with a clear speed-over-everything bias. Put simply, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. A lower, longer stance usually helps you ride more efficiently in the wind once speed picks up. With rims around 62mm deep, the wheels clearly lean toward an aero setup. Deeper rims like this can matter on open roads once speeds rise. That tyre width is common on performance road builds and tends to suit aero goals. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. The faster you ride, the more this aero focus tends to show up in how it holds speed.

Race / Pro fit - a low, stretched position built for speed and aerodynamics. This is mainly because bars are around 146 mm lower than the saddle, which is a very large drop, and the forward stretch measures around 597 mm (very long). Plan for roughly 46 degrees of lean.

Fit flexibility summary: A modular front-end gives more freedom to change stem length or bar width, Cable routing is on the simpler side, which helps adjustability. Also, Seatpost details do not strongly point to a very locked-in or very flexible system. That is why we tag it Moderately Adjustable. Put simply, it describes how practical it is to reconfigure your position later.

Comfort comes out to 1.8/10, which usually translates to a very firm ride. So it’s tagged Race-Stiff overall. It’s running about 25 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is race-leaning (posture 8/10, torso ~46°), which puts more weight forward, so you notice more feedback through the hands and saddle.

This feels like you’re paying extra for the same kind of bike. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). On the spec comparison, it sits roughly 26% above what similar builds typically cost. Compared with similar bikes, it trends a little expensive (cheaper than about 39% of listings). Quick reference: €7.350 listed versus about €5.838 for a comparable build. A few manufacturer details aren’t clearly published, so treat this as a best-effort estimate, not a precise verdict. Overall, it doesn’t look like the best value for the spec.

This bike is best when your rides stay on clean tarmac. The tire size is around 25 mm, which is typical for fast road setups. Wheel choice (700c) fits the kind of surfaces this bike targets.
