Endurance SL e – Hero, Shimano Dura Ace Di2

It's built to carry momentum with less wasted effort. On paved roads, the rating is mostly about fast cruising and how the setup supports higher speeds. The setup that matters most here is a heavier build, all-round road tires that balance speed and comfort, and a high-end drivetrain that tends to feel crisp under load. On paper, aero efficiency is a major part of the speed feel here.

If your rides include hills, it rates 2.2/10 for climbing. Within e-road bikes, it ranks below average. For hill work, the easiest gear is very tall. The easiest gear works out to about 76.5 gear inches. This sits at the tough end — easier than only about ~1% of similar bikes. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. At about 10.5 kg, it’s in a normal range, so gearing matters more than weight swings here. The motor support helps you keep rolling when the slope kicks up. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. 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.

Looking at it as an endurance setup, at 6.3/10 for aerodynamics, it lands in the ‘do-most-things-well’ aero zone so it sits comfortably in the all-rounder lane. In everyday language, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. A lower front end can help you tuck in a bit, even if the bike itself isn’t built as an aero specialist. This tyre size generally plays nicely with aero goals compared with very wide all-road tyres. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. Different brands share different amounts of detail, so this uses the most consistent cues that are available. That typically means solid everyday speed without forcing an aggressive position or race-only parts.

Balanced fit - a middle ground between comfort and speed. You get this posture because bars are around 103 mm lower than the saddle, which is a large drop, and the forward stretch measures around 561 mm (long). Estimated lean is about 40 degrees. Endurance bikes often keep the front end a bit higher for longer rides.

Overall, it falls into Adjustable. What affects adjustability on this bike: Because the bar and stem are separate, changing reach or bar shape is usually straightforward. Also, The front-end is easier to work on, supporting fit tweaks over time. This mainly reflects how easy it is to adjust or swap key fit parts over time.

This scores 4.0/10 for comfort, so it feels firm out on the road. That’s the reason it lands as Firm. It’s running about 28 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 7/10, torso ~40°), which puts more weight forward, so you notice more feedback through the hands and saddle.

Against comparable bikes, this comes out looking overpriced. 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 33% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 10% of them. To anchor it: price €10.610 versus an estimated €7.985 for a similar build. Put simply: it’s priced more like a premium pick than a value buy.

This setup is focused on speed and efficiency on paved roads. Tires around 28 mm usually mean it’s tuned for smooth-road speed. Wheel choice (700c) fits the kind of surfaces this bike targets.
