Belgian custom bikebuilder Jaegher adds new top-tier stainless steel FL.X Ascender Phoenix to their road bike line-up, leveraging 3D-printing and Artificial Intelligence to give the bike the smooth curves we expect from modern carbon bikes. Calling it a “step into the future”, the new stainless steel Jaegher Ascender Phoenix road bike is made-to-measure for each buyer with a 3D-printed headtube, ‘tailfin’ seat cluster, and dropouts that add up to seamlessly smooth good looks. And of course that classic lifetime steel ride…

I always love to ogle beautifully-crafted handmade steel bikes. And we never really tire of seeing cool 3D-printed parts find their way into the bike building process. So Jaegher’s latest creation is our kind of jam.

Debuted over the weekend at their home Velofollies show, Jaegher created their latest fully-custom Ascender Phoenix road bike by mixing the latest in manufacturing tech up against the most advanced iteration of the most classic bike building material.

In order to match 3D-printed stainless steel parts with a fully-customizable fit, they let a parametric model powered by AI tweak the shaping of the headtube, seat cluster & dropout alignment. Then, they can just pop in the straight top tube and seatstays. Weld it all up, and the end result is as curvy as carbon, with all that makes stainless steel bikes great.
Ride it hard for a lifetime. High stiffness, yet tuned compliance. No corrosion or crash damage worries. And no paint needed, really. Although, Jaegher does some great paintjobs that highlight the beauty of stainless steel without going overboard.
