AK105 Full Carbon Racing Bike 24S

On paved roads, the rating is mostly about fast cruising and how the setup supports higher speeds. In comparison with more aero-focused bikes, this build is shaped by typical road tire sizing assumptions, aerodynamics that likely help it hold speed once you're rolling, and a solid drivetrain that supports efficient riding. That's why it's not at the sharpest end of outright speed.

On steep roads, it comes in at 1.1/10. Within Road bikes, this comes out near the bottom. This setup leans heavily toward ‘push’ rather than ‘spin’ on climbs. Your easiest gear lands around 42.2 gear inches. Most comparable bikes have an easier low gear; this is easier than only about ~2% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. 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 race-focused build, with more integrated details, sitting at 7.5/10 for aero, it’s shaped to hold speed once you’re moving quickly so it tends to hold speed efficiently. The short version is: it’s built with speed in mind, with choices that reduce wind drag once you’re riding faster. Different categories trade aerodynamics against comfort and stability—race is part of that story. Rims around 50mm are more of an all-round choice than a pure aero choice. That wheel depth is more all-round than purely aero-focused. A tidier cockpit and cable routing can help a little once you’re riding quickly. When you’re riding quickly, this kind of design can feel easier to keep rolling at the same speed.

Sporty fit - you'll lean forward more and feel ready to push the pace. Based on full geometry data.

So we classify it as Adjustable. Here is the simple reasoning behind the fit flexibility rating: Separate bar and stem components keep fit changes practical - Cable routing is on the simpler side, which helps adjustability.

Comfort comes out to 2.8/10, which usually translates to a quite direct ride. That’s the reason it lands as Firm. The posture is race-leaning (posture 7/10), which tends to feel more direct, especially over rougher sections.

This looks like a great buy for the spec on paper. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the parts list, it’s roughly 73% cheaper than what similar builds typically cost. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 100% of listings. To anchor it: price €1.699 versus an estimated €6.216 for a similar build. Bottom line: you’re getting a lot of bike for the money compared with typical options.

This bike is built for smooth pavement and fast road riding. The tire size is unknown in this entry, so the surface range is based on the clearest available signals. Overall, the setup matches this surface range well.
