A.C.E. Tubing 

A.C.E. is seamless, custom extruded tubing that is heat treated and air hardened. This allows us to use the thinnest walls practical while maintaining strength and weight targets. Rather than accept the offerings from a tubing supplier, as is the case with our Reynolds, Columbus, and 612 Select varieties, A.C.E. allows our engineer to go completely custom with the butting profiles, diameters, shape and wall thickness'. We do this not only on the main tubes, but on the stays as well. Full frame heat treating and customization that yields a tubeset holistically designed and engineered for ride characteristics, strength, and weight savings. 

This level of customization opens up a whole new world of possibilities to tune the ride and feel of our line and makes our A.C.E. tubing bikes completely unique. 

While we will be expanding the line of A.C.E. tubing bicycles over the years, it is not something that we plan on moving every model to. In many cases the off-the-shelf tubing options meet our needs swimmingly, but for when we really need to go deep on a project, you can expect to see the A.C.E. tubing badge. 

For the Cosmic Staillion the tubeset was engineered with several goals in mind: 

  • A significant weight savings over our existing 853 frames 
  • Enhanced bump absorption 
  • Increased stiffness  
  • Increased fatigue life  

So how did we do?

Well, we managed to shave 5oz off our Reynolds 853 built Macho King in the 55cm size, and in testing, the Cosmic Stallion exceeded our requirements by a significant factor. In fact, after it doubled the amount of required test cycles we simply turned the machines off. (Hey machine time, is expensive and we knew what we had to know!) This thing is plenty strong, and significantly lighter than any disc model we've ever produced.  

It also sports a number of frame features that are firsts for All-City: 

Integrated headset 
Tapered headtube 
New Signature thru-axle dropout 
Shaped Stays 
Di2 Compatibility  
 
When we say that this is without a doubt our finest work to date, this what we're talking about. Never before seen features, a fully custom tubeset specifically designed for the application, weight savings, and increased strength. The numbers tell part of the story, but you'll have to ride one for yourself to get the rest.
