The ARC8 Eero sits in the fast-gravel camp with a clear brief: maximise efficiency on the road while staying highly capable off-road. The frame uses aero-profiled tube shapes and fully internal routing to trim drag. Double chainring compatibility suits riders who alternate between committed gravel rides and group road outings.

Frame, fork and claimed weights

• Frame: ARC8 Eero carbon
• Fork: ARC8 Eero carbon
• Frame weight: 990 g (unpainted, size M)
• Fork weight: 395 g (cut for size M)
• Sizes: S / M / L / XL

The design features slender, dropped seatstays. According to ARC8, the layup (developed via FEA simulations) is intended to filter vibrations, while stiff chainstays preserve power transfer.

Tyre clearance and drivetrain

• Tyre clearance: up to 700c x 50 mm
• Drivetrain: compatible with 1x and 2x (double chainring possible)

With 50 mm of clearance, the Eero covers a wide spectrum: fast-rolling 35–40 mm tyres for road and fast gravel, larger sections for rough tracks or soft terrain.

Handling and intended use

The geometry is designed to inspire confidence in technical sections without losing the responsiveness of a drop-bar bike. The Eero is aimed at riders who go fast on tracks, without giving up long asphalt transfers.

Mounts and utility features

• Two bottle-cage mounts positioned low to free up space for a frame bag
• Additional mounts on the top tube and under the down tube
• Rear rack eyelets
• Mudguard eyelets

These options extend usage to light bikepacking as well as all-weather daily commutes.

Who is it for?

The Eero suits performance-oriented gravel riders who want:

• A fast bike on tracks, able to keep up with a road group
• Generous tyre clearance (up to 50 mm)
• 1x or 2x options depending on terrain and elevation gain
• Full mounts for everyday versatility or bikepacking

Key takeaways

• Light, aero-profiled carbon frame, fully internal routing
• Generous clearance: 700c x 50 mm
• Varied builds with Shimano GRX (mechanical and Di2) and SRAM AXS
• Full eyelets: mudguards, racks, bags
• Price range: about €4,399 to €8,499, frameset at €2,699

Our take

The ARC8 Eero ticks the boxes of a modern race-focused gravel bike: large clearance, an aero-profiled frame, 2x options and a range of electronic builds. At a claimed 990 g (unpainted frame, M), it sits in the solid middle of the performance segment, without chasing the extreme lightness of a Specialized Crux, while offering more utility options (mudguards and racks) than some pure-speed competitors. Against fast-gravel benchmarks (3T Exploro/Racemax, Cervélo Áspero), the Eero stands out with its 50 mm clearance and numerous mounting points, a duo that broadens use without sacrificing speed.
