The design of SICURO Carbon focuses on three factors: perfectly matched geometry, lateral stability and vibration damping. The majority of water bottle ejections in carbon cages happen because the cage fails to prevent the bottle from walking upward when exposed to certain frequencies of vibration. Most companies try to solve this by increasing grip force on the bottle, making it harder to insert and remove. The problem with this is that along with wearing out bottles, the tight grip can actually hold the bottle in a semi-ejected state as it walks upward when exposed to certain washboard type surfaces, placing it perfectly to be ejected on the next large hit. Using our multi-axis shake rig and high speed cameras, we learned that we could use less grip force combined with a perfectly matched forward lip geometry and our unique 'wings' on the sides of the cage to drive the bottle back down into the cage under these same frequencies. We learned that we could further eliminate walking of the bottle by adding a film of viscoelastic polymer to the layup, allowing the cage itself to reduce the vibration forces on the bottle.
The result: No walking, no ejecting.
One of the most interesting learnings to come out of the testing phase for this product was the effect that cage bolts had on both bottle retention as well as cage fatigue life. Each SICURO Carbon bottle cage comes with two of our premium Titanium Mounting Bolts. Each bolt is machined complete in one operation from 6Al/4V Titanium on a Swiss Lathe. The low-profile flange head design of the bolt distributes load across nearly 3x more surface area than a cap screw and 2x the surface area of a button head for increased rigidity and lower stress.
SICURO Carbon Bottle Cages feature the same elongated mounting slots that we pioneered with the introduction of our SICURO Titanium Bottle Cages. These elongated mounting slots give you up to 16mm of fore/aft adjustment to account for the variance in bottle boss location across different frame manufacturers. Lastly, the bottom of SICURO Carbon bottle cages contain a unique accessory mounting platform, something we’re excited to expand upon in the near future.
