Aerfast.5 Pro Dura Ace 2×12 Classified Powershift

For road riding, the score leans toward outright pace rather than comfort-first priorities. Put simply, it's biased toward performance over comfort-focused choices. Most of the story comes from a very light build, a lighter-feeling mass profile that helps on accelerations and tempo climbs, narrow road tires that keep resistance low, and a high-end drivetrain that tends to feel crisp under load.

Overall on climbs: 7.9/10. Within Road bikes, it ranks above average. For hill work, the easiest gear is moderate. Your easiest gear lands around 28.6 gear inches. In its peer group, it lands around the easier ~43% for low-gear climbing. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. With about 6.9 kg under you, it has a nice advantage when gravity is the main enemy. A good middle-ground if you want mixed routes that include some hills. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

On the aero side of things, an aero score of 9.1/10 means that with very deep wheels (~62mm), it’s built with a ‘race the wind’ mindset and it’s meant to pay you back at high speed. In everyday language, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. The aero category also hints at the intent behind the design. With rims around 62mm deep, the wheels clearly lean toward an aero setup. That rim depth is a classic aero-leaning choice for faster riding. This tyre size generally plays nicely with aero goals compared with very wide all-road tyres. Different brands share different amounts of detail, so this uses the most consistent cues that are available. The faster you ride, the more this aero focus tends to show up in how it holds speed.

Sporty fit - a performance-leaning position that encourages speed. Mostly geometry-based, with a small category-based estimate.

In Road / Aero, That is why it is in the Adjustable bucket. Main reasons for the fit flexibility result: This front-end is not locked into a one-piece system, which helps adjustability; Routing is relatively straightforward, which helps when you change cockpit parts.

This scores 2.3/10 for comfort, so it feels stiff-feeling out on the road. That’s the reason it lands as Race-Stiff. It’s running about 25 mm tires, and narrow tires usually mean higher pressure, so more buzz comes through on chipseal and broken pavement. The posture is race-leaning (posture 7/10), which tends to feel more direct, especially over rougher sections.

For the spec, this is priced well into premium territory. 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 45% above what similar builds typically cost. Compared with similar bikes, it trends a little expensive (cheaper than about 38% of listings). To anchor it: price €10.290 versus an estimated €7.081 for a similar build. Put simply: it’s priced more like a premium pick than a value buy.

This setup is focused on speed and efficiency on paved roads. Tires around 25 mm usually mean it’s tuned for smooth-road speed. Overall, the setup matches this surface range well.
