Calmly gliding over bumpy ground at immense speed. Superhero feeling. A bike that emulates how Eero Hämäläinen became a rally legend.

The Eero is built to be fast on tarmac but best on gravel. With aerodynamic tube shapes, cables hidden from the wind, a lightweight frame and the ability to run double chainrings, this bike does not hold you back on paved roads. You can comfortably join that weekly road group ride on the Eero without your friends realizing that you are on a bike that is even better elsewhere.

Designing the frame specifically with the latest gravel groupsets in mind allowed us to create space for tires up to 700c x 50. And you cannot defy physics, as soon as the ground gets bumpy or soft, wide tires are faster. We designed the geometry to increase confidence in challenging terrain without losing the sharpness, responsivity and quick handling we love about drop bar bikes. Thin, lowered seat stays and a layup refined by the use of FEA simulation software absorb vibrations and hits coming from the ground, while sturdy chainstays make sure no energy is lost. All this combined means you will fly along gravel roads like Eero, leaving your competition in the dust.

But Eero was also a nature lover and bon vivant who liked to explore. We are sure he would have made good use of the multiple storage options and rack mounts, loading up his bike to disappear into the wilderness between races. We placed two bottle cages low in the frame to leave enough room for a frame bag. Additional mounts on the top tube and below the down tube let you carry your essentials, and if that is not enough there are mounts for a rear carrier.

Your weekly diet of riding includes a ride to work? With fender mounts you will arrive dry even on wet days despite having the fastest commuter bike in the streets.

Frequently asked questions

On the Eero, you can ride tires up to 50mm width (700Cx50), when you're using a Oneby drivetrain. However, please note that the tire width may vary depending on the inner rim width of the wheel.

On the Eero, we install a handlebar with a 12-degree flare. If you prefer a handlebar with more flare, we can also offer you a handlebar with a 30-degree flare.

The Eero has mounts for full fenders and a rear rack. Additionally, you find mounts on the top tubes and under the down tube for more storage.

The maximum load weight for a luggage carrier on the Eero is 10 kg. We recommend an even load and avoiding one-sided loading (e.g. mounting the entire weight on one side only).

Unfortunately, the Eero is not fully compatible with a road bike groupset. A standard road bike drivetrain from Shimano, for example, is not compatible with the Eero. However, if this is exactly what you are looking for, then it would be possible to use a FSA or Easton crank (in combination with Shimano) or a SRAM Wide groupset.
