Venturi STC 105 Di2 Tailormade

For road riding, the score leans toward outright pace rather than comfort-first priorities. Several build choices play a role, including 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 combination, they decide how the bike feels when rolling along.

How it climbs: 2.8/10. Within Road bikes, it lands below average. 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. 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. 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.

Coming in at 9.0/10 on aero, aero is one of the main points of the design and it’s meant to pay you back at high speed. Put simply, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. 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. Aero intent typically nudges you into a sleeker position. Mostly geometry-based, with a small category-based estimate.

Because the bar and stem are separate, changing reach or bar shape is usually straightforward, Hidden cables usually add a little friction when you swap bars or stems. Another point: Notable system naming mentioned: SMR. Overall, it is Moderately Adjustable.

Comfort comes out to 2.5/10, which usually translates to a harsh on rough surfaces ride. So it’s tagged Race-Stiff overall. The posture is race-leaning (posture 7/10), which puts more weight forward, so you notice more feedback through the hands and saddle.

This looks like strong value without any tricky caveats. 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 95% of listings. To anchor it: price €4.126 versus an estimated €6.302 for a similar build. Put simply: this is strong value for what’s included.

This setup is focused on speed and efficiency on paved roads. Tire size details aren’t available here, so the label follows the overall setup and category cues. Overall, the setup matches this surface range well.
