Planet X Pro Carbon Shimano 105 R7100

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. What pushes it in this direction is narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, and a solid drivetrain that supports efficient riding. This means it sits toward the faster end for comparable bikes.

Overall on climbs: 3.3/10. Within Road bikes, this comes out below average. The low gear is workable, but not super easy on steep ramps. That lowest gear comes out around 27.0 gear inches. Compared with similar bikes, this low gear is easier than about ~58% of them. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. 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.

At 7.2/10 for aerodynamics, it’s aero-aware without going extreme so it’s more efficient than it looks once you’re rolling. In everyday language, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The wheels are on the shallower side (around 30mm), so frame shapes and position likely matter more than wheel depth here. That wheel depth is more all-round than purely aero-focused. 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 - you'll lean forward more and feel ready to push the pace. This is mainly because there's about 100 mm of drop to the bars (large), with roughly 563 mm of forward stretch to the bar (long). Expect a lean angle around 39 degrees.

That is why it is in the Adjustable bucket. Fit adjustability is shaped by a few key choices: Separate bar and stem components keep fit changes practical, Cable routing is on the simpler side, which helps adjustability. Also, The listed seatpost details do not show clear restrictions or extra flexibility signals. In practice, it is about how easy fit changes are with normal parts and service work.

Comfort comes out to 2.2/10, which usually translates to a very firm ride. That’s why it’s labeled Race-Stiff. It’s running about 25 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is neutral (posture 6/10, torso ~39°), which balances comfort and responsiveness pretty well.

For what you get, the price looks very hard to beat. 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 46% 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 97% of listings. Quick reference: €2.218 listed versus about €4.124 for a comparable build. Put simply: this is strong value for what’s included.

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. Wheel choice (700c) fits the kind of surfaces this bike targets.
