Synapse Carbon 3 L

On asphalt, it's mainly a question of resistance and efficiency, and that's what the score summarizes. When stacked up next to faster-rolling setups, this build is shaped by all-round road tires that balance speed and comfort, an aero-leaning setup that reduces drag at higher speeds, and a solid drivetrain that supports efficient riding. As a result, it tends to feel slower when you try to hold a high tempo.

Overall on climbs: 3.3/10. Within Road bikes, this comes out below average. It has a middle-of-the-road low gear for climbing. The easiest gear works out to about 27.0 gear inches. On the ‘easier low gear’ scale, it sits around ~58% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. 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.

On the endurance side of things, at 6.2/10 for aerodynamics, with tyres around 30mm, it aims for usable speed without big trade-offs so it works well across lots of riding. The short version is: it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The endurance category also hints at the intent behind the design. Tyres around 30mm are a practical middle ground, with a small aero trade-off compared with narrower race tyres. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. It’s a middle-ground feel: not the fastest possible in the wind, but not holding you back either.

Comfort fit - less tuck and easier on neck and shoulders. Based on full geometry data.

In Road / Endurance, That is why we tag it Moderately Adjustable. Why this fit flexibility rating: This front-end is not locked into a one-piece system, which helps adjustability. Also, Internal routing is a mild hit to swap-and-go adjustability.

Comfort comes out to 4.8/10, which usually translates to a fairly neutral ride. That’s why it’s labeled Balanced. It’s running about 30 mm tires on 700c wheels, and it softens the edges a little, without feeling plush on chipseal and broken pavement. The posture is neutral (posture 5/10), which keeps things neutral and easy to live with.

This looks like a typical market price for the spec. 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). Based on the spec estimate, it’s about 12% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 56% of listings). Quick reference: €3.325 listed versus about €2.971 for a comparable build. Overall, it sits in the expected range for the category.

This bike is best when your rides stay on clean tarmac. Tires around 30 mm usually mean it’s tuned for smooth-road speed. Even though it’s tagged Endurance, the spec pushes it toward Road Only.
