Turbine SLR SHIMANO ULTEGRA Di2 R8170

It's tuned to feel quick when you push the speed. On asphalt, it's mainly a question of resistance and efficiency, and that's what the score summarizes. Several build choices play a role, including narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, a high-end drivetrain that tends to feel crisp under load, and a relaxed posture that gives up some aero efficiency.

Overall on climbs: 1.8/10. Within Road bikes, it sits near the bottom. On climbs, the lowest gear feels tall. Your easiest gear lands around 32.4 gear inches. Compared with similar bikes, this low gear is easier than about ~18% of them. 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. 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.

As a triathlon bike, at 9.8/10 for aerodynamics, it’s built to minimize air resistance at pace where aerodynamics is the main lever. What that means on the road is: it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. Its triathlon label helps explain the balance between speed, comfort, and versatility. Tyres around 25mm fit a faster road setup and usually keep drag in check. Specs can vary by market and model year, so the summary follows the strongest published signals. If you ride at higher speeds, this is the kind of bike that’s designed to pay you back for that effort.

Race / Pro fit - a very performance-focused fit with more load on core and arms. Because you get a very large drop: roughly 132 mm from saddle to bar, plus about 608 mm of stretch forward (very long). You'll likely be near 43 degrees of lean. Tri bikes are designed around a very forward, tucked position when fitted.

What affects adjustability on this bike: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, Routing is relatively straightforward, which helps when you change cockpit parts. Another point: The listed seatpost details do not show clear restrictions or extra flexibility signals. That is why we tag it Moderately Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Ride comfort is 1.9/10 — on a real ride it feels harsh on rough surfaces. That’s the reason it lands as Race-Stiff. It’s running about 25 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 ~43°), which tends to feel more direct, especially over rougher sections.

You’re paying a big premium here versus similar builds. 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 comparison, it sits roughly 84% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 8% of them. To anchor it: price €10.396 versus an estimated €5.637 for a similar build. Put simply: it’s priced more like a premium pick than a value buy.

This bike is built for smooth pavement and fast road riding. Tires around 25 mm usually mean it’s tuned for smooth-road speed. Wheel choice (700c) fits the kind of surfaces this bike targets.
