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).

Climbing rating: 1.8/10. Within e-road bikes, it sits near the bottom. For hill work, the easiest gear is very tall. Your easiest gear lands around 32.4 gear inches. On the ‘easier low gear’ scale, it sits around ~12% 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. E-assist can take the sting out of steep ramps, especially at lower speeds. This is happiest on flatter terrain; steep stuff will feel demanding. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

In race-focused terms, scoring 7.0/10 on aero, it’s tuned for mixed riding rather than pure aero focus 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. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. 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 559 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.

This scores 3.0/10 for comfort, so it feels quite direct out on the road. That’s why it’s labeled Firm. The posture is neutral (posture 6/10, torso ~38°), which balances comfort and responsiveness pretty well.

This bike is built for smooth pavement and fast road riding. The tire size is unknown in this entry, so the surface range is based on the clearest available signals. The wheel setup (700c) supports that direction.
