Old Beliefs, Modern Technology
Clears a 29 x 2.25 tire, ridiculously fun, unbelievably fast.

We decided to make a thoroughly modern gravel space ship cutting no corners, cost be danged. You'll find the finest double butted titanium tubing, full internal cable routing, a custom T47 bottom bracket shell, it's UDH compatible, and fits the big tires. 

The Heighliner is built in Taiwan by our friends at ORA, the same folks who build Dark Stars and Mean Jeans. Their work is absolutely impeccable. 

Designers Notes
I can tell you with the utmost sincerity that this is the most fun drop bar bike I've ever ridden. I feel such joy when I ride it, like the toughest thing on two wheels. Unstoppable. It’s an absolute monster in the dirt, becoming ever more fun the harder you push. I was very much a skeptic of the big tire trend, but off-road it’s superb and on pavement it’s still pretty fast. In a world of gravel bikes that are becoming more and more specialized at going in straight lines and don't really want to turn, the Heighliner is nimble, agile, playful, and I find myself reaching for it ride after ride after ride.

Why Titanium? The first Wilde ever built was my own titanium Earth Ship, the prototype for every Wilde gravel bike that would follow. The ride quality of a high end titanium frame is simply sublime and it offers significant weight savings. As I've always counseled our customers, "if titanium is in the budget, go Ti. You won't be disappointed." Just like our steel production bikes, the Heighliner allows us to bring the titanium experience to more riders via a significantly reduced cost compared to our USA made customs. 

In case you were wondering, the name is a Dune reference. From Dune Wiki: "A Heighliner was a large starship used by the Spacing Guild to transport people and equipment, and could fold space to travel vast distances."
Yeah, we folding friggin' space. 
Blaise named it. I did the geo, he did the development.
