Planet X Tempest Shimano GRX RX820 Titanium

It prioritizes confidence and everyday riding over outright pace. For road bikes, the speed score favors setups that waste less energy at higher speeds. Most of the story comes from wider mixed-surface tires that add some drag, aerodynamics that help it hold speed once you're rolling, and a solid drivetrain that supports efficient riding.

How it climbs: 4.2/10. Within Road bikes, it ranks around the middle. On longer climbs, the gearing lands on the easy side. Your easiest gear lands around 24.0 gear inches. Compared with similar bikes, this low gear is easier than about ~81% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. It can climb, but you’ll likely prefer smoother pacing on longer 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 gravel side of things, with a 4.7/10 aero score, it’s tuned for mixed riding rather than pure aero focus and it doesn’t force a specialist aero posture. In everyday language, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Different categories trade aerodynamics against comfort and stability—gravel is part of that story. A lower front end can help you tuck in a bit, even if the bike itself isn’t built as an aero specialist. That tyre width leans toward grip and stability first, with a small aero penalty at speed. Specs can vary by market and model year, so the summary follows the strongest published signals. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Balanced fit - a neutral road posture that suits most riders. That's driven by bars are around 103 mm lower than the saddle, which is a large drop, and the forward stretch measures around 559 mm (long). You'll likely be near 40 degrees of lean.

Why this fit flexibility rating: This front-end is not locked into a one-piece system, which helps adjustability, The front-end is easier to work on, supporting fit tweaks over time; The listed seatpost details do not show clear restrictions or extra flexibility signals. Net result: Adjustable. In practice, it is about how easy fit changes are with normal parts and service work.

Ride comfort is 5.9/10 — on a real ride it feels balanced. So it’s tagged Balanced overall. It’s running about 40 mm tires on 700c wheels, and wider tires let you drop pressure a touch, which smooths out rough pavement on rough lanes and gravel patches. The posture is race-leaning (posture 7/10, torso ~40°), which tends to feel more direct, especially over rougher sections.

From a value angle, this comes out as a standout deal. 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 spec estimate, it comes in about 24% under the typical level for similar builds. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 87% of listings. To anchor it: price €2.870 versus an estimated €3.782 for a similar build. Overall, it looks like a great-value pick in its category.

This bike is comfortable on gravel roads and unpaved back roads, and it still rides well on tarmac. Tires around 40 mm are well suited for gravel roads and unpaved connectors. Overall, the setup matches this surface range well.
