Speedmax CF SLX 8 Di2

This road speed rating is tuned for paved riding - think steady fast tempo and easier acceleration. The score is largely shaped by a fairly average weight, all-round road tires that balance speed and comfort, a high-end drivetrain that tends to feel crisp under load, and a relaxed posture that gives up some aero efficiency.

How it climbs: 5.0/10. Within Road bikes, it sits around the middle. On longer climbs, the gearing lands on the tall side. Your easiest gear lands around 32.4 gear inches. On the ‘easier low gear’ scale, it sits around ~18% versus similar bikes. 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 9.4 kg, which is typical for this kind of build. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

Category-wise (triathlon), scoring 10.0/10 on aero, aero is one of the main points of the design and it’s built to feel efficient at pace. The short version is: it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. The triathlon category also hints at the intent behind the design. A lower, longer stance usually helps you ride more efficiently in the wind once speed picks up. With rims around 62mm deep, the wheels clearly lean toward an aero setup. That rim depth is a classic aero-leaning choice for faster riding. 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. The faster you ride, the more this aero focus tends to show up in how it holds speed.

Race / Pro fit - an aggressive tuck meant for hard efforts over pure comfort. This is mainly because the bar sits about 111 mm below the saddle (a large drop), and you'll be stretched forward about 627 mm in total (very long). Estimated lean is about 39 degrees.

In Road / Triathlon, So it lands in Moderately Adjustable. What affects adjustability on this bike: Standard cockpit parts make it simpler to fine-tune your position over time, Hidden cables usually add a little friction when you swap bars or stems. Also, This seatpost design is more specific than a round standard post, which reduces flexibility. In practice, it is about how easy fit changes are with normal parts and service work.

Comfort comes out to 2.4/10, which usually translates to a harsh on rough surfaces ride. So it’s tagged Race-Stiff overall. It’s running about 27 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 8/10, torso ~39°), which tends to feel more direct, especially over rougher sections.

This reads like a good buy compared with similar bikes. 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 74% of listings. To anchor it: price €8.925 versus an estimated €9.083 for a similar build. Bottom line: it compares well against similar bikes.

This setup is focused on speed and efficiency on paved roads. Tires around 28 mm usually mean it’s tuned for smooth-road speed. Overall, the setup matches this surface range well.
