Venturi STC 105 Di2

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. Compared with trail-speed specialists, this build is shaped by 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. In practice, it's a balanced setup rather than a pure speed machine.

If your rides include hills, it rates 3.3/10 for climbing. Within Road bikes, it sits below average. The low gear is workable, but not super easy on steep ramps. The easiest gear works out to about 27.0 gear inches. Compared with similar bikes, this low gear is easier than about ~58% of them. “Gear inches” sounds nerdy, but it’s just a quick way to describe how easy your lowest gear is to turn uphill. Lower usually means easier. 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.

Seen as an aero option, at 9.0/10 for aerodynamics, with tidier routing up front, aero is one of the main points of the design so the faster you ride, the more it shows. In everyday language, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. 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. Not every brand publishes the same detail, so this leans on the clearest available specs. On fast flats and windy days, it’s built to feel like it wastes less energy pushing air.

Sporty fit - you'll lean forward more and feel ready to push the pace. Mostly geometry-based, with a small category-based estimate.

This rating is mainly driven by the parts that affect adjustability: Separate bar and stem components keep fit changes practical, With headset routing, adjustments often require more disassembly. Also, Seatpost info looks fairly neutral, so most fit change comes from cockpit choices. Net result: 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 quite direct ride. That’s the reason it lands as Firm. It’s running about 28 mm tires, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is race-leaning (posture 7/10), which tends to feel more direct, especially over rougher sections.

Compared to similar bikes, this is priced very competitively. 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 40% 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 98% of listings. Quick reference: €3.237 listed versus about €5.371 for a comparable build. Overall, it looks like a great-value pick in its category.

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. Overall, the setup matches this surface range well.
