Specialissima COMP 105 Di2

For road bikes, this score reflects how easily the bike carries speed on smooth tarmac. What pushes it in this direction is 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. These factors stack up and show up most at higher speeds or higher effort.

Climb score: 1.2/10. Within Road bikes, it ranks near the bottom. On steep gradients, you’ll be grinding more than spinning. The easiest gear works out to about 36.0 gear inches. This sits at the tough end — easier than only about ~4% of similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. Expect more grinding on climbs than easy spinning. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

Looking at it as a race-focused setup, aero-wise, at 8.2/10, on a 26mm tyre setup, it’s shaped to hold speed once you’re moving quickly so it rewards steady fast riding. 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. 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. This looks like a practical wheel choice rather than a max-aero choice. This tyre size generally plays nicely with aero goals compared with very wide all-road tyres. Not every brand publishes the same detail, so this leans on the clearest available specs. When you’re riding quickly, this kind of design can feel easier to keep rolling at the same speed.

Sporty fit - more tuck for efficiency, but still manageable for many riders. Because you get a large drop: roughly 104 mm from saddle to bar, plus about 570 mm of stretch forward (long). Estimated lean is about 39 degrees. Race-focused geometry usually rewards a more tucked posture.

In Road / Race, This rating is mainly driven by the parts that affect adjustability: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts. Plus, Routing through the headset can make cockpit swaps harder than normal internal routing. Net result: Moderately Adjustable. In practice, it is about how easy fit changes are with normal parts and service work.

This scores 2.4/10 for comfort, so it feels stiff-feeling out on the road. 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.

This doesn’t look like the best deal once you compare it to similar builds. 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 34% above what similar builds typically cost. Compared with similar bikes, it trends a little expensive (cheaper than about 43% of listings). Quick reference: €5.929 listed versus about €4.419 for a comparable build. Put simply: it’s a bit pricey for what you get.

This setup is focused on speed and efficiency on paved roads. The tire size is unknown in this entry, so the surface range is based on the clearest available signals. Overall, the setup matches this surface range well.
