Gold STC 105 Di2

This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. So overall, it trades speed for comfort, durability, or practicality. 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.

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. Your easiest gear lands around 27.0 gear inches. Compared with similar bikes, this low gear is easier than about ~58% of them. 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.

Rated 6.2/10 for aero, it’s an all-round aero level so it won’t hold you back on normal fast riding. The short version is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Tyres around 28mm fit a faster road setup and usually keep drag in check. Different brands share different amounts of detail, so this uses the most consistent cues that are available. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Comfort fit - comfort-leaning without feeling sluggish. Mostly geometry-based, with a small category-based estimate.

Fit flexibility summary: Because the bar and stem are separate, changing reach or bar shape is usually straightforward; A more service-friendly routing setup makes changes easier. Net result: Adjustable.

This scores 4.2/10 for comfort, so it feels quite direct out on the road. So it’s tagged Firm overall. 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 neutral (posture 5/10), which balances comfort and responsiveness pretty well.

This looks like strong value, even if it’s not the absolute cheapest listing. 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). On the spec estimate, the price is close to what we’d expect for a comparable build. In its peer group, it tends to be better-priced than many, beating about 72% of listings. To anchor it: price €3.237 versus an estimated €3.385 for a similar build. Overall, it looks like a strong buy 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. Even though it’s tagged Endurance, the spec pushes it toward Road Only.
