REACTO 4000

On asphalt, it's mainly a question of resistance and efficiency, and that's what the score summarizes. In day-to-day use, it's quick enough for most rides, but not a pure fastest-possible build. It ends up here thanks to a fairly average weight, an aero-leaning setup that reduces drag at higher speeds, all-round road tires that balance speed and comfort, and a solid drivetrain that supports efficient riding.

Climbing rating: 6.1/10. Within Road bikes, this comes out around the middle. The low gear is workable, but not super easy on steep ramps. The easiest gear works out to about 28.6 gear inches. On the ‘easier low gear’ scale, it sits around ~47% 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. Weight is around 9.0 kg, which is typical for this kind of build. Good for keeping cadence steady on climbs without overcooking it. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

An aero score of 9.0/10 means that with more integrated details, drag reduction is a headline goal and it’s built to feel efficient at pace. In everyday language, 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. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. If you ride at higher speeds, this is the kind of bike that’s designed to pay you back for that effort.

Sporty fit - more tuck for efficiency, but still manageable for many riders. You get this posture because bars are around 99 mm lower than the saddle, which is a large drop, and the forward stretch measures around 577 mm (long). You'll likely be near 38 degrees of lean.

In Road, This front-end is not locked into a one-piece system, which helps adjustability, Less routing complexity makes swaps and adjustments more practical, and Seatpost info looks fairly neutral, so most fit change comes from cockpit choices. That is why it is in the Adjustable bucket. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Comfort comes out to 3.0/10, which usually translates to a firm ride. That’s why it’s labeled Firm. It’s running about 28 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 ~38°), which puts more weight forward, so you notice more feedback through the hands and saddle.

This is the kind of deal people usually notice quickly. 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 17% 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 85% of listings. Quick reference: €2.996 listed versus about €3.631 for a comparable build. Put simply: this is strong value for what’s included.

This setup is focused on speed and efficiency on paved roads. The tire size is around 28 mm, which is typical for fast road setups. Wheel choice (700c) fits the kind of surfaces this bike targets.
