After spending years spent lusting over Italian tubed road bikes, we decided to build one of our own. Columbus’ Zona tubeset offered an unbeatable combination of suppleness, lightweight, and stiffness.
In Electrophoretic Deposition, or E.D., coating the frame or fork is placed in a paint bath where an electric charge is applied. This fuses a thin layer of black satin coating to the tubes inside and out. This coating acts as both a rust preventative inside and a primer out.
We’re way into the handbuilt touches when it comes to our frames. Which is why you’ll find things like internal cable routing, custom dropouts, lugged crown forks, reinforcements on the bottle bosses, hidden fender mounts, etc on our framesets.
Investment cast, stainless steel with a beautiful lugged lower portion, and “All-City” on the pads.
