Grail:ON CF 8

It prioritizes confidence and everyday riding over outright pace. This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. It trends this way because of a heavier build, very wide tires that create extra drag, and a solid drivetrain that supports efficient riding. The effect is most noticeable when you're chasing a faster average speed or riding into wind.

Climbing rating: 6.7/10. Within e-road bikes, it ranks above average. The low gear should feel friendly on most hills. Your easiest gear lands around 19.3 gear inches. Compared with similar bikes, this low gear is easier than about ~94% of them. “Gear inches” sounds nerdy, but it’s just a quick way to describe how easy your lowest gear is to turn uphill. Lower usually means easier. At about 16.6 kg, it’s a heavy build; the low gear matters even more when the slope kicks up. E-assist can take the sting out of steep ramps, especially at lower speeds. Good for keeping cadence steady on climbs without overcooking it. 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.

From a gravel perspective, coming in at 4.5/10 on aero, it’s tuned for mixed riding rather than pure aero focus and it doesn’t force a specialist aero posture. Put simply, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The gravel category also hints at the intent behind the design. This setup supports a more race-leaning posture, helping you present less of your body to the wind. Tyres around 50mm are clearly aimed at comfort and control, and that usually adds some drag in the wind. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Balanced fit - a versatile position for long rides and faster efforts. You get this posture because the cockpit sits 95 mm below the saddle (a large drop), and the cockpit stretches you forward by ~578 mm (long). Estimated lean is about 38 degrees.

Net result: Adjustable. Main reasons for the fit flexibility result: A modular front-end gives more freedom to change stem length or bar width, A more service-friendly routing setup makes changes easier. Another point: Offset options make it easier to get the saddle where you need it. Put simply, it describes how practical it is to reconfigure your position later.

Comfort comes out to 6.7/10, which usually translates to a nicely smooth ride. That’s why it’s labeled Balanced. It’s running about 50 mm tires on 700c wheels, and wider tires let you drop pressure a touch, which smooths out rough pavement on rough lanes and gravel patches. The posture is race-leaning (posture 7/10, torso ~38°), which tends to feel more direct, especially over rougher sections.

From a value angle, this comes out as a standout deal. 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 comes in about 19% under the typical level for similar builds. Against similar bikes of the same type and age, it’s usually on the cheaper side, beating about 89% of listings. Quick reference: €4.999 listed versus about €6.154 for a comparable build. Put simply: this is strong value for what’s included.

This bike is aimed at exploring off the main roads on tougher mixed terrain. The tire size is around 50 mm, which supports comfort and control on rougher ground. The wheel setup (700c) supports that direction.
