REACTO 6000 Di2

On asphalt, it's mainly a question of resistance and efficiency, and that's what the score summarizes. Key drivers include 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. In combination, they decide how the bike feels when rolling along.

On steep roads, it comes in at 3.3/10. Within Road bikes, it sits below average. The low gear is workable, but not super easy on steep ramps. That lowest gear comes out around 27.0 gear inches. In its peer group, it lands around the easier ~58% 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. 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.

From an aero perspective, with a more tucked fit, coming in at 9.3/10 on aero, drag reduction is a headline goal and it’s built to feel efficient at pace. What that means on the road is: it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. The aero tag is a useful clue for how wind efficiency ranks among the priorities. A lower front end can help you tuck in a bit, even if the bike itself isn’t built as an aero specialist. 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. Tyres around 25mm fit a faster road setup and usually keep drag in check. On fast flats and windy days, it’s built to feel like it wastes less energy pushing air.

Sporty fit - a performance-leaning position that encourages speed. It feels this way because the bar sits about 101 mm below the saddle (a large drop), and you'll be stretched forward about 574 mm in total (long). Estimated lean is about 39 degrees.

That is why we tag it Moderately Adjustable. Here is the simple reasoning behind the fit flexibility rating: This front-end is not locked into a one-piece system, which helps adjustability. Plus, A headset-integrated routing system reduces practical flexibility for cockpit changes. Put simply, it describes how practical it is to reconfigure your position later.

This scores 2.1/10 for comfort, so it feels stiff-feeling out on the road. That’s why it’s labeled 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 ~39°), 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. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. 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 13% under the typical level for similar builds. In its peer group, it tends to be better-priced than many, beating about 80% of listings. To anchor it: price €4.245 versus an estimated €4.859 for a similar build. Put simply: this is strong value for what’s included.

This bike is best when your rides stay on clean tarmac. Tires around 25 mm usually mean it’s tuned for smooth-road speed. Overall, the setup matches this surface range well.
