Diamante SV Shimano Ultegra 8170 Di2 Disc

It tends to feel lively when you accelerate or surge. In a road context, the speed rating is about holding pace with less effort once you're up to speed. The score is largely 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.

How it climbs: 2.3/10. Within Road bikes, it sits below average. On climbs, the lowest gear feels tall. The easiest gear works out to about 30.6 gear inches. On the ‘easier low gear’ scale, it sits around ~32% versus similar bikes. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. Good for keeping cadence steady on climbs without overcooking it. 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.

On the race-focused side of things, at 7.2/10 for aerodynamics, with a fairly neutral fit, it lands in the ‘do-most-things-well’ aero zone and it doesn’t force a specialist aero posture. What that means on the road is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The fit looks fairly neutral, so aerodynamics depends more on the overall design and components than on an extreme position. That tyre width is common on performance road builds and tends to suit aero goals. That typically means solid everyday speed without forcing an aggressive position or race-only parts.

Sporty fit - you'll lean forward more and feel ready to push the pace. That's driven by bars are around 97 mm lower than the saddle, which is a large drop, and the forward stretch measures around 564 mm (long). Estimated lean is about 38 degrees. Race-focused geometry usually rewards a more tucked posture. Front-end spacers are estimated around 11 mm.

Why this fit flexibility rating: Because the bar and stem are separate, changing reach or bar shape is usually straightforward. Another point: A more service-friendly routing setup makes changes easier. Overall, it falls into Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

This scores 3.2/10 for comfort, so it feels quite direct out on the road. That’s the reason it lands as Firm. It’s running about 28 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is neutral (posture 6/10, torso ~38°), which keeps things neutral and easy to live with.

Against comparable bikes, this comes out looking overpriced. 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 comparison, it sits roughly 85% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 19% of them. To anchor it: price €7.350 versus an estimated €3.976 for a similar build. Overall, you can likely find better value elsewhere.

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.
