GXA Aluminium Disc Gravel Bike – Shimano-12s-105 R7170 DI2

This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. A few practical factors stand out: all-round road tires that balance speed and comfort, an aero-leaning setup that reduces drag at higher speeds, a solid drivetrain that supports efficient riding, and a more tucked riding position that cuts wind resistance.

How it climbs: 3.3/10. Within Road bikes, this comes out below average. It has a middle-of-the-road low gear for climbing. In numbers, the low gear is roughly 27.0 gear inches. On the ‘easier low gear’ scale, it sits around ~58% versus similar bikes. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. A good middle-ground if you want mixed routes that include some hills. 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.

Category-wise (gravel), at 4.7/10 for aerodynamics, it keeps decent wind efficiency without becoming a specialist so it feels ‘quick enough’ without being a pure aero build. In everyday language, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The fit looks fairly neutral, so aerodynamics depends more on the overall design and components than on an extreme position. That typically means solid everyday speed without forcing an aggressive position or race-only parts.

Comfort fit - comfort-leaning without feeling sluggish. That's driven by the cockpit sits 62 mm below the saddle (a moderate drop), and the cockpit stretches you forward by ~545 mm (long). Plan for roughly 32 degrees of lean. Front-end spacers are estimated around 20 mm.

In Road, Main reasons for the fit flexibility result: A modular front-end gives more freedom to change stem length or bar width - A more service-friendly routing setup makes changes easier. Net result: Adjustable.

Ride comfort is 4.4/10 — on a real ride it feels moderately comfortable. That’s the reason it lands as Firm. It’s running about 32 mm tires on 700c wheels, and it softens the edges a little, without feeling plush on rough lanes and gravel patches. The posture is neutral (posture 5/10, torso ~32°), which keeps things neutral and easy to live with.

In simple terms, it comes out as ‘about right’ for the category. 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). On the spec estimate, the price is close to what we’d expect for a comparable build. Among comparable bikes, it sits around the middle on price (cheaper than about 56% of listings). To anchor it: price €2.870 versus an estimated €2.681 for a similar build. Put simply: you’re paying roughly what similar bikes tend to cost.

This setup works well when your ride switches between tarmac and easy unpaved sections. The tire size is around 32 mm, which supports mixed routes without feeling slow on road. It’s listed as Gravel, but the setup aligns better with All Road.
