Venturi STC Ultegra Di2

It's designed for a mix of riding rather than top-end pace. This road speed rating is tuned for paved riding - think steady fast tempo and easier acceleration. It trends this way because of all-round road tires that balance speed and comfort, an aero-leaning setup that reduces drag at higher speeds, and a solid drivetrain that supports efficient riding.

Climb score: 1.8/10. Within Road bikes, this comes out near the bottom. You may find yourself pushing a bit more on steeper grades. The easiest gear works out to about 32.4 gear inches. In its peer group, it lands around the easier ~18% for low-gear climbing. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. Expect more grinding on climbs than easy spinning. 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.

Seen as an aero option, scoring 9.2/10 on aero, running tyres around 28mm, it’s a speed-first, wind-focused setup with a clear speed-over-everything bias. What that means on the road is: it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. Its aero label helps explain the balance between speed, comfort, and versatility. Rims around 35mm are more of an all-round choice than a pure aero choice. 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. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. On fast flats and windy days, it’s built to feel like it wastes less energy pushing air.

Sporty fit - more tuck for efficiency, but still manageable for many riders. Aero intent typically nudges you into a sleeker position. Some measurements were missing, so part of this is estimated.

Main reasons for the fit flexibility result: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, A headset-integrated routing system reduces practical flexibility for cockpit changes. Also, Seatpost info looks fairly neutral, so most fit change comes from cockpit choices. That is why we tag it Moderately Adjustable. Put simply, it describes how practical it is to reconfigure your position later.

Comfort comes out to 3.1/10, which usually translates to a firm ride. That’s why it’s labeled Firm. It’s running about 28 mm tires, 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), 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 parts list, it’s roughly 35% 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 96% of listings. Quick reference: €3.850 listed versus about €5.948 for a comparable build. Overall, it looks like a great-value pick in its category.

This bike is built for smooth pavement and fast road riding. The tire size is around 28 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
