Tributary GRX 600 US

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. It trends this way because of a heavier build, very wide tires that create extra drag, a solid drivetrain that supports efficient riding, and a more tucked riding position that cuts wind resistance. It's the combination that matters: weight, rolling resistance, and (for road) aerodynamics.

How it climbs: 5.1/10. Within e-road bikes, it lands around the middle. It’s set up for steady spinning on climbs. Your easiest gear lands around 20.7 gear inches. Compared with similar bikes, this low gear is easier than about ~91% of them. 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 20.9 kg — on steep, slow climbs that extra mass becomes more noticeable. E-assist can take the sting out of steep ramps, especially at lower speeds. It’s set up so climbs feel controlled rather than a grind. 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.

An aero score of 4.4/10 means that it’s built for everyday ease over airflow tricks so it’s happier when the route gets rough than when it gets windy. Put simply, it’s more about stability and everyday comfort than cutting through the wind. The gravel tag is a useful clue for how wind efficiency ranks among the priorities. The fit looks fairly neutral, so aerodynamics depends more on the overall design and components than on an extreme position. The wheels are on the shallower side (around 27mm), so frame shapes and position likely matter more than wheel depth here. This looks like a practical wheel choice rather than a max-aero choice. It’s built for ease and control, not for squeezing out speed against the wind.

Balanced fit - a neutral road posture that suits most riders. Because the bar sits about 24 mm below the saddle (a very small drop), and you'll be stretched forward about 587 mm in total (very long). You'll likely be near 25 degrees of lean. Gravel setups typically avoid an extreme tuck for stability. Spacer height is roughly 17 mm.

This front-end is not locked into a one-piece system, which helps adjustability, Routing is relatively straightforward, which helps when you change cockpit parts. Plus, The dropper post improves on-the-fly position changes. That is why it is in the Adjustable bucket.

Ride comfort is 6.1/10 — on a real ride it feels easygoing over rough patches. That’s the reason it lands as Balanced. The posture is neutral (posture 5/10), which keeps things neutral and easy to live with.

This sits in a nice value spot for its category. 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 70% of listings. To anchor it: price €5.499 versus an estimated €5.753 for a similar build. Bottom line: it compares well against similar bikes.

This bike is built for everyday trails with a mix of roots, rocks, and turns. Suspension travel details aren’t available here, so the label follows the category and the rest of the setup. Suspension type (Rigid) fits this kind of terrain.
