At Sea Otter we took a closer look at the Alchemy Airon, an aero road bike that won the best carbon construction award at the North American Handmade Bike Show in Denver, CO earlier this year. Custom frame, fork, headset, seatpost and clamp of this Boulder, CO based brand can be had for $4,550 and the customer can also opt for a round seattube and seatpost.

The Alchemy Arion looks fast standing still.

An Enve fork up front matches the bike quite nicely.

The carbon layup is very visible in the sun light.

This bike had a Zipp cockpit and Mavic wheels.
