GXE Carbon Disc Gravel Bike – Shimano 12s 105 R7170-DI2

This road speed rating is tuned for paved riding - think steady fast tempo and easier acceleration. The strongest influences are all-round road tires that balance speed and comfort, an aero-leaning setup that reduces drag at higher speeds, and a solid drivetrain that supports efficient riding. Those ingredients add up to a setup that either preserves speed or bleeds it off.

On steep roads, it comes in at 3.3/10. Within e-road bikes, this comes out below average. On climbs, the lowest gear feels moderate. The easiest gear works out to about 27.0 gear inches. On the ‘easier low gear’ scale, it sits around ~54% 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. Being an e-bike helps on climbs because the assist adds steady push when you need it. Good for keeping cadence steady on climbs without overcooking it. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

Seen as a gravel option, that 5.2/10 aero rating suggests that with more integrated details, it keeps decent wind efficiency without becoming a specialist so it won’t hold you back on normal fast riding. The short version is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. Not every brand publishes the same detail, so this leans on the clearest available specs. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Balanced fit - a middle ground between comfort and speed. It feels this way because there's about 86 mm of drop to the bars (large), with roughly 540 mm of forward stretch to the bar (long). You'll likely be near 37 degrees of lean.

Standard cockpit parts make it simpler to fine-tune your position over time, A more service-friendly routing setup makes changes easier. At the same time, This seatpost design is more specific than a round standard post, which reduces flexibility. Overall, it falls into Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

This scores 4.5/10 for comfort, so it feels fairly neutral out on the road. So it’s tagged Firm overall. It’s running about 32 mm tires on 700c wheels, and there’s a bit of cushion, but it still rides fairly direct on rough pavement on rough lanes and gravel patches. The posture is neutral (posture 5/10, torso ~37°), which balances comfort and responsiveness pretty well.

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). Based on the spec estimate, it’s about 23% above the typical level for similar builds. Compared with similar bikes, it trends a little expensive (cheaper than about 29% of listings). To anchor it: price €6.990 versus an estimated €5.670 for a similar build. A few manufacturer details aren’t clearly published, so treat this as a best-effort estimate, not a precise verdict. Bottom line: you may be paying extra versus similar options.

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. Even though it’s tagged Gravel, the spec pushes it toward All Road.
