Turbine SHIMANO DURA ACE 9270 Di2 12S

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. The main reasons are narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, a high-end drivetrain that tends to feel crisp under load, and a relaxed posture that gives up some aero efficiency. Together, these choices shape rolling resistance and how lively the bike feels.

On steep roads, it comes in at 1.8/10. Within Road bikes, it sits near the bottom. The easiest gear is on the tall side for proper hills. Your easiest gear lands around 32.4 gear inches. Compared with similar bikes, this low gear is easier than about ~18% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. Expect more grinding on climbs than easy spinning. 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.

As a triathlon bike, rated 9.8/10 for aero, it’s at the sharp end of aero priorities and it’s meant to pay you back at high speed. 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. The faster you ride, the more this aero focus tends to show up in how it holds speed.

Race / Pro fit - a low, stretched position built for speed and aerodynamics. Because there's about 139 mm of drop to the bars (very large), with roughly 602 mm of forward stretch to the bar (very long). Plan for roughly 45 degrees of lean. Spacer height is roughly 6 mm.

Main reasons for the fit flexibility result: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, Cable routing is on the simpler side, which helps adjustability. Plus, Seatpost info looks fairly neutral, so most fit change comes from cockpit choices. Overall, it is Moderately Adjustable.

This scores 1.8/10 for comfort, so it feels stiff-feeling out on the road. So it’s tagged Race-Stiff overall. It’s running about 25 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 race-leaning (posture 8/10, torso ~45°), which puts more weight forward, so you notice more feedback through the hands and saddle.

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 90% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 6% of them. To anchor it: price €10.711 versus an estimated €5.637 for a similar build. Overall, you can likely find better value elsewhere.

This setup is focused on speed and efficiency on paved roads. Tires around 25 mm usually mean it’s tuned for smooth-road speed. Overall, the setup matches this surface range well.
