SRfive – Dura-Ace Di2 12 Speed

For road bikes, this score reflects how easily the bike carries speed on smooth tarmac. A few practical factors stand out: all-round road tires that balance speed and comfort and a high-end drivetrain that tends to feel crisp under load. Net effect: the bike either carries speed well or feels like more work to keep it rolling. On paper, aero efficiency is a major part of the speed feel here.

Overall on climbs: 1.8/10. Within Road bikes, it ranks near the bottom. On climbs, the lowest gear feels tall. In numbers, the low gear is roughly 32.4 gear inches. In its peer group, it lands around the easier ~18% for low-gear climbing. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. This is happiest on flatter terrain; steep stuff will feel demanding. 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.

Category-wise (triathlon), coming in at 10.0/10 on aero, aero is one of the main points of the design where aerodynamics is the main lever. Put simply, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. Tyres around 28mm fit a faster road setup and usually keep drag in check. On fast flats and windy days, it’s built to feel like it wastes less energy pushing air.

Balanced fit - a neutral road posture that suits most riders. You get this posture because handlebar height is roughly 100 mm lower than the saddle (large drop), and how far you'll be stretched forward is about 569 mm (long). Plan for roughly 39 degrees of lean. Tri bikes are designed around a very forward, tucked position when fitted.

In Road, Fit adjustability is shaped by a few key choices: A modular front-end gives more freedom to change stem length or bar width. Plus, Routing through the headset can make cockpit swaps harder than normal internal routing. Net result: Moderately Adjustable.

Comfort comes out to 3.2/10, which usually translates to a firm ride. That’s why it’s labeled 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 neutral (posture 6/10, torso ~39°), which balances comfort and responsiveness pretty well.

For the spec, this feels competitively priced. 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 estimate, the price is close to what we’d expect for a comparable build. In its peer group, it tends to be better-priced than many, beating about 80% of listings. Quick reference: €6.629 listed versus about €7.112 for a comparable build. Overall, it looks like a strong buy in its category.

This bike is built for smooth pavement and fast road riding. The tire size is around 28 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
