Chiron Dura Ace Di2
All Road // Titanium // 38mm Max Width // Starting At $7499
Titanium All Road Bike
The Chiron boasts state-of-the-art titanium craftsmanship for the cyclocross and gravel connoisseur. Easily the highest performance and most stunning titanium bike in any starting grid. S-bend seat and chain stays dampen the ride and keep the rear tire tracking while also offering more tire clearance than a traditional CX or Gravel frame. Chiron’s tapered down tube and top tube translate into increased stiffness and torque at the bottom bracket. American-made seamless 3a/2.5v titanium tubing creates a frame that holds up to any abuse and delivers world-beating performance.

Frameset Features
Proprietary Alchemy USA-Made Titanium
The first frame Alchemy produced was titanium, and it immediately received accolades and awards. That didn’t mean we rested on our laurels though. Over the years, we have continued to develop and refine our titanium bikes. Five years ago, we took a giant step and did what few in our industry dared to do: we created our own proprietary USA-made titanium tubing. It’s the reason we have been able to stay one step ahead of the competition, and the reason why Alchemy continues to produce titanium bikes that are heads-and-tails superior to other bikes on the market.

Oversize and Shaped Top and Down Tubes
Take a close look at an Chiron frame…do you see the unique profile and oversize shape of the top and down tubes? Do you see the way the down tube flares, seamlessly flowing into the bottom bracket? This of course helps create a visually-stunning Alchemy bike, but there is also science behind the art. The oversize tubes and proprietary shapes create a bike which is stiff but comfortable, compliant yet responsive, fast and capable, yet easy to handle in the most demanding conditions. It’s the reason why Alchemy continues to earn accolades for making the best titanium bikes in the business.
Natural or Painted Ti Options
Alchemy continues to be one of the few companies in the world that is able to paint titanium. At our Ethic paint studio, housed inside Alchemy headquarters, we have obsessively perfected the process of painting titanium to both create a unique and durable frame. And we can do custom paint as well…perfectly designed to meet your creative imagination.
