Turbine SHIMANO ULTEGRA 8170 Di2 12S

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. Several build choices play a role, including narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, a solid drivetrain that supports efficient riding, and a relaxed posture that gives up some aero efficiency.

On steep roads, it comes in at 1.8/10. Within Road bikes, it sits near the bottom. You may find yourself pushing a bit more on steeper grades. That lowest gear comes out around 32.4 gear inches. On the ‘easier low gear’ scale, it sits around ~18% versus similar bikes. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. 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.

Looking at it as a triathlon setup, at 9.8/10 for aerodynamics, it’s built to minimize air resistance at pace where aerodynamics is the main lever. What that means on the road is: it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. A lower, longer stance usually helps you ride more efficiently in the wind once speed picks up. This tyre size generally plays nicely with aero goals compared with very wide all-road tyres. Not every brand publishes the same detail, so this leans on the clearest available specs. If you ride at higher speeds, this is the kind of bike that’s designed to pay you back for that effort.

Race / Pro fit - a very performance-focused fit with more load on core and arms. That's driven by you get a very large drop: roughly 139 mm from saddle to bar, plus about 602 mm of stretch forward (very long). Expect a lean angle around 45 degrees. Tri bikes are designed around a very forward, tucked position when fitted.

What drives the fit flexibility here: This front-end is not locked into a one-piece system, which helps adjustability, and Cable routing is on the simpler side, which helps adjustability. That is why we tag it Moderately Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

This scores 1.8/10 for comfort, so it feels harsh on rough surfaces out on the road. So it’s tagged Race-Stiff overall. It’s running about 25 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is race-leaning (posture 8/10, torso ~45°), which tends to feel more direct, especially over rougher sections.

This looks expensive compared with similar bikes. 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 comparison, it sits roughly 84% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 8% of them. Quick reference: €9.031 listed versus about €4.899 for a comparable build. Put simply: it’s priced more like a premium pick than a value buy.

This bike is built for smooth pavement and fast road riding. The tire size is around 25 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
