Planet X Pro Carbon Shimano Ultegra Di2

It's one of the more speed-focused builds in its group. In a road context, the speed rating is about holding pace with less effort once you're up to speed. A few practical factors stand out: a fairly average weight, an aero-leaning setup that reduces drag at higher speeds, narrow road tires that keep resistance low, and a solid drivetrain that supports efficient riding.

How it climbs: 6.2/10. Within Road bikes, it ranks around the middle. For hill work, the easiest gear is moderate. The easiest gear works out to about 28.6 gear inches. In its peer group, it lands around the easier ~47% for low-gear climbing. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. Weight is around 8.8 kg, which is typical for this kind of build. A good middle-ground if you want mixed routes that include some hills. 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.

With a 7.3/10 aero score, it aims for usable speed without big trade-offs so it won’t hold you back on normal fast riding. Put simply, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Its race label helps explain the balance between speed, comfort, and versatility. The fit looks fairly neutral, so aerodynamics depends more on the overall design and components than on an extreme position. That tyre width is common on performance road builds and tends to suit aero goals. That typically means solid everyday speed without forcing an aggressive position or race-only parts.

Sporty fit - more tuck for efficiency, but still manageable for many riders. This is mainly because you get a large drop: roughly 99 mm from saddle to bar, plus about 562 mm of stretch forward (long). Estimated lean is about 39 degrees.

Fit flexibility summary: Separate bar and stem components keep fit changes practical. Also, A more service-friendly routing setup makes changes easier. Net result: Adjustable.

This scores 2.2/10 for comfort, so it feels very firm out on the road. That’s the reason it lands as Race-Stiff. It’s running about 25 mm tires on 700c wheels, and narrow tires usually mean higher pressure, so more buzz comes through on chipseal and broken pavement. The posture is neutral (posture 6/10, torso ~39°), which keeps things neutral and easy to live with.

This looks like a typical market price for the spec. 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 55% of listings). To anchor it: price €4.493 versus an estimated €4.331 for a similar build. Put simply: you’re paying roughly what similar bikes tend to cost.

This bike is best when your rides stay on clean tarmac. The tire size is around 25 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
