NYTRO E9 ROAD – DURA ACE Di2

This road speed rating is tuned for paved riding - think steady fast tempo and easier acceleration. In day-to-day use, it's one of the more speed-focused builds in its group. The main reasons are a baseline tire-width assumption and a high-end drivetrain that tends to feel crisp under load. Under the hood, aero efficiency is a major part of the speed feel here (based on typical road assumptions).

Overall on climbs: 1.8/10. Within e-road bikes, this comes out near the bottom. For hill work, the easiest gear is very tall. In numbers, the low gear is roughly 32.4 gear inches. On the ‘easier low gear’ scale, it sits around ~12% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. The motor support helps you keep rolling when the slope kicks up. Expect more grinding on climbs than easy spinning. 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.

For a race-focused build, sitting at 7.0/10 for aero, it aims for usable speed without big trade-offs without demanding big compromises elsewhere. What that means on the road is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. Specs can vary by market and model year, so the summary follows the strongest published signals. That typically means solid everyday speed without forcing an aggressive position or race-only parts.

Balanced fit - a neutral road posture that suits most riders. This is mainly because you get a large drop: roughly 95 mm from saddle to bar, plus about 560 mm of stretch forward (long). Estimated lean is about 38 degrees.

That is why it is in the Adjustable bucket. A modular front-end gives more freedom to change stem length or bar width, and Less routing complexity makes swaps and adjustments more practical. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Ride comfort is 3.0/10 — on a real ride it feels more responsive than cushy. So it’s tagged Firm overall. The posture is neutral (posture 6/10, torso ~38°), which balances comfort and responsiveness pretty well.

This bike is best when your rides stay on clean tarmac. Tire size details aren’t available here, so the label follows the overall setup and category cues. Overall, the setup matches this surface range well.
