S-Works Shiv TT Disc Module – Speed of Light Collection

It's not at the sharpest end of outright speed. This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. It ends up here thanks to a default tire-width baseline, aerodynamics that likely help it hold speed once you're rolling, a basic drivetrain spec that prioritizes practicality over outright performance, and a relaxed posture that gives up some aero...

On steep roads, it comes in at 1.8/10. Within Road bikes, it sits near the bottom. On climbs, the lowest gear feels tall. In numbers, the low gear is roughly 32.4 gear inches. In its peer group, it lands around the easier ~18% for low-gear climbing. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. 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.

On the triathlon side of things, that 10.0/10 aero rating suggests that 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. This setup supports a more race-leaning posture, helping you present less of your body to the wind. Not every brand publishes the same detail, so this leans on the clearest available specs. On fast flats and windy days, it’s built to feel like it wastes less energy pushing air.

Race / Pro fit - an aggressive tuck meant for hard efforts over pure comfort. This is mainly because you get a very large drop: roughly 138 mm from saddle to bar, plus about 647 mm of stretch forward (extreme). Expect a lean angle around 43 degrees. Spacer height is roughly 5 mm.

A one-piece cockpit locks the front-end setup more than separate bar and stem parts, The front-end is easier to work on, supporting fit tweaks over time. Another point: This seatpost design is more specific than a round standard post, which reduces flexibility. Overall, it is Race-Fit Specific. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Ride comfort is 2.7/10 — on a real ride it feels firm. That’s why it’s labeled Firm. The posture is race-leaning (posture 9/10, torso ~43°), which puts more weight forward, so you notice more feedback through the hands and saddle.

Against comparable bikes, this comes out looking overpriced. 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 34% above what similar builds typically cost. Compared with similar bikes, it trends a little expensive (cheaper than about 30% of listings). Quick reference: €7.000 listed versus about €5.215 for a comparable build. Not every spec detail is consistently published, so think of this as a strong hint rather than the last word. Bottom line: the price looks high for what’s included.

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.
