Planet X EC-130 Shimano Ultegra Di2

For road bikes, this score reflects how easily the bike carries speed on smooth tarmac. This means it's biased toward performance over comfort-focused choices. A few practical factors stand out: 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.

If your rides include hills, it rates 2.8/10 for climbing. 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 28.6 gear inches. In its peer group, it lands around the easier ~47% for low-gear climbing. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. 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 an aero option, with shallow rims (~30mm), at 8.8/10 for aerodynamics, drag reduction is a headline goal with a clear speed-over-everything bias. Put simply, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. A lower, longer stance usually helps you ride more efficiently in the wind once speed picks up. The wheels are on the shallower side (around 30mm), so frame shapes and position likely matter more than wheel depth here. This looks like a practical wheel choice rather than a max-aero choice. Tyres around 25mm fit a faster road setup and usually keep drag in check. Not every brand publishes the same detail, so this leans on the clearest available specs. The faster you ride, the more this aero focus tends to show up in how it holds speed.

Sporty fit - more tuck for efficiency, but still manageable for many riders. This is mainly because you get a very large drop: roughly 121 mm from saddle to bar, plus about 565 mm of stretch forward (long). You'll likely be near 42 degrees of lean. Estimated spacers: ~10 mm.

In Road, Because the bar and stem are separate, changing reach or bar shape is usually straightforward. At the same time, Cable routing is on the simpler side, which helps adjustability. Net result: Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Comfort comes out to 2.1/10, which usually translates to a stiff-feeling ride. 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 race-leaning (posture 7/10, torso ~42°), which tends to feel more direct, especially over rougher sections.

This sits in a nice value spot for its 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. In its peer group, it tends to be better-priced than many, beating about 69% of listings. To anchor it: price €5.087 versus an estimated €5.115 for a similar build. Overall, it looks like a strong buy in its category.

This setup is focused on speed and efficiency on paved roads. 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.
