Grail:ON CF 7 eTap

On paved roads, the rating is mostly about fast cruising and how the setup supports higher speeds. It ends up here thanks to a heavier build, very wide tires that create extra drag, and a solid drivetrain that supports efficient riding. When you combine them, you can feel the difference most when you surge or climb at tempo. That's why it trades speed for comfort, durability, or practicality.

How it climbs: 7.5/10. Within e-road bikes, it ranks above average. The low gear should feel friendly on most hills. That lowest gear comes out around 18.4 gear inches. For the low gear, it’s right at the easy end — easier than about ~96% of 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 17.1 kg — on steep, slow climbs that extra mass becomes more noticeable. Being an e-bike helps on climbs because the assist adds steady push when you need it. This kind of low gear helps you stay smooth on long or steep climbs. 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.

Category-wise (gravel), aero-wise, at 4.5/10, it’s aero-aware without going extreme so it won’t hold you back on normal fast riding. In everyday language, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Wider tyres like this tend to trade a bit of aero efficiency for comfort and confidence. It’s a middle-ground feel: not the fastest possible in the wind, but not holding you back either.

Balanced fit - a middle ground between comfort and speed. This is mainly because bars are around 95 mm lower than the saddle, which is a large drop, and the forward stretch measures around 578 mm (long). You'll likely be near 38 degrees of lean. Estimated spacers: ~14 mm.

Overall, it falls into Adjustable. Why this fit flexibility rating: This front-end is not locked into a one-piece system, which helps adjustability, Cable routing is on the simpler side, which helps adjustability. Plus, A fliphead or multi-offset option increases fit range. In practice, it is about how easy fit changes are with normal parts and service work.

Ride comfort is 6.7/10 — on a real ride it feels comfortable. That’s the reason it lands as Balanced. It’s running about 50 mm tires on 700c wheels, and extra tire volume helps mute vibration and small bumps on rough lanes and gravel patches. The posture is race-leaning (posture 7/10, torso ~38°), which puts more weight forward, so you notice more feedback through the hands and saddle.

This looks like a great buy for the spec on paper. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the spec estimate, it comes in about 12% under the typical level for similar builds. In its peer group, it tends to be better-priced than many, beating about 79% of listings. Quick reference: €5.249 listed versus about €5.937 for a comparable build. Not every spec detail is consistently published, so think of this as a strong hint rather than the last word. Put simply: this is strong value for what’s included.

This bike is aimed at exploring off the main roads on tougher mixed terrain. Tires around 50 mm usually point to more stability on tough mixed terrain. Even though it’s tagged Gravel, the spec pushes it toward Adventure.
