Izoard 105 Di2

For road-style bikes, the score is a proxy for how fast the build feels on normal pavement. When you push the pace, it's one of the more speed-focused builds in its group. What pushes it in this direction is a fairly average weight, an aero-leaning setup that reduces drag at higher speeds, all-round road tires that balance speed and comfort, and a solid drivetrain that supports efficient riding.

Uphill performance score: 7.4/10. Within Road bikes, this comes out above average. On climbs, the lowest gear feels moderate. Your easiest gear lands around 27.0 gear inches. Compared with similar bikes, this low gear is easier than about ~58% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. Weight is around 8.5 kg, which is typical for this kind of build. It can climb, but you’ll likely prefer smoother pacing on longer hills. 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.

From a race-focused perspective, with a 7.8/10 aero score, it tends to shine more on flats and into headwinds so it tends to hold speed efficiently. What that means on the road is: it’s built with speed in mind, with choices that reduce wind drag once you’re riding faster. 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. In real riding, it tends to reward holding speed: the faster you go, the more the aero design helps.

Sporty fit - you'll lean forward more and feel ready to push the pace. It feels this way because the cockpit sits 103 mm below the saddle (a large drop), and the cockpit stretches you forward by ~572 mm (long). Expect a lean angle around 39 degrees. Estimated spacers: ~10 mm.

In Road / Race, What drives the fit flexibility here: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, Internal routing looks tidy but can make cockpit changes a bit more fiddly. Also, A round post makes fit changes simpler than proprietary shapes. That is why it is in the Adjustable bucket.

This scores 3.1/10 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 neutral (posture 6/10, torso ~39°), which keeps things neutral and easy to live with.

For what you get, the price looks very hard to beat. 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). Based on the parts list, it’s roughly 30% cheaper than what similar builds typically cost. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 89% of listings. Quick reference: €3.149 listed versus about €4.478 for a comparable build. Put simply: this is strong value for what’s included.

This bike is best when your rides stay on clean tarmac. 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.
