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.

If your rides include hills, it rates 3.3/10 for climbing. Within Road bikes, it sits below average. On climbs, the lowest gear feels moderate. Your easiest gear lands around 27.0 gear inches. In its peer group, it lands around the easier ~58% 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. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. 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.

On the endurance side of things, running tyres around 28mm, sitting at 6.2/10 for aero, it’s built to be well-rounded in the wind 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. That tyre width is common on performance road builds and tends to suit aero goals. It’s a middle-ground feel: not the fastest possible in the wind, but not holding you back either.

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.

Comfort comes out to 4.1/10, which usually translates to a more responsive than cushy ride. That’s the reason it lands as Firm. It’s running about 28 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 neutral (posture 5/10), which keeps things neutral and easy to live with.

Nothing screams bargain or rip-off here. 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). 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 66% of listings. To anchor it: price €3.439 versus an estimated €3.385 for a similar build. Bottom line: it’s a normal deal — not amazing, not terrible.

This setup is focused on speed and efficiency on paved roads. Tires around 28 mm usually mean it’s tuned for smooth-road speed. It’s listed as Endurance, but the setup aligns better with Road Only.
