Specialissima COMP Ultegra Di2

For road bikes, this score reflects how easily the bike carries speed on smooth tarmac. Put simply, it's built to carry momentum with less wasted effort. The biggest contributors are narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, and a solid drivetrain that supports efficient riding. Over a longer ride, it tends to feel more lively when you increase the pace.

How it climbs: 1.1/10. Within Road bikes, it sits near the bottom. For hill work, the easiest gear is very tall. In numbers, the low gear is roughly 40.5 gear inches. This sits at the tough end — easier than only about ~2% 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. Expect more grinding on climbs than easy spinning. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

From a race-focused perspective, on a 26mm tyre setup, sitting at 8.2/10 for aero, it leans toward speed once pace rises so it rewards steady fast riding. The short version is: it’s built with speed in mind, with choices that reduce wind drag once you’re riding faster. A lower, longer stance usually helps you ride more efficiently in the wind once speed picks up. Rims around 33mm are more of an all-round choice than a pure aero choice. These wheels lean more toward stability and versatility than pure aero. That tyre width is common on performance road builds and tends to suit aero goals. A tidier cockpit and cable routing can help a little once you’re riding quickly. Not every brand publishes the same detail, so this leans on the clearest available specs. On flatter roads and into headwinds, this kind of setup often feels noticeably quicker than more comfort-first designs.

Sporty fit - you'll lean forward more and feel ready to push the pace. This is mainly because bar height comes out ~104 mm below the saddle (large), with about 570 mm of forward reach - a long stretch. Plan for roughly 39 degrees of lean.

What affects adjustability on this bike: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, Routing through the headset can make cockpit swaps harder than normal internal routing. Plus, The listed seatpost details do not show clear restrictions or extra flexibility signals. Net result: Moderately Adjustable.

Ride comfort is 2.4/10 — on a real ride it feels very firm. That’s why it’s labeled Race-Stiff. It’s running about 26 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 ~39°), which puts more weight forward, so you notice more feedback through the hands and saddle.

The value looks a bit weak compared with similar options. 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 27% above what similar builds typically cost. Among comparable bikes, it sits around the middle on price (cheaper than about 47% of listings). Quick reference: €6.366 listed versus about €5.006 for a comparable build. Put simply: it’s a bit pricey for what you get.

This bike is built for smooth pavement and fast road riding. Tire size details aren’t available here, so the label follows the overall setup and category cues. Wheel choice (700c) fits the kind of surfaces this bike targets.
