About Silca Sicuro Carbon Bottle Cage
The Sicuro Carbon Bottle Cage is the result of combining their more than 40 years of carbon fiber engineering and manufacturing experience with their first in the world 3 stage bottle cage testing protocols developed for the Sicuro Titanium Cage development. True to their namesake, Sicuro (meaning secure), the design of these bottle cages was directly driven from hundreds of lab tests, and high speed video of cage behavior during these tests and more than a year of on road testing.
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 their multi-axis shake rig and high speed cameras, they learned that they could use less grip force combined with a perfectly matched forward lip geometry and their unique 'wings' on the sides of the cage to drive the bottle back down into the cage under these same frequencies. Silca learned that they 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 their 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 they pioneered with the introduction of their 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 they’re excited to expand upon in the near future.

More About The Manufacturer Silca
Silca pumps are serviceable in seconds. They require no tools for disassembly, and the few parts that wear out are easy to replace. The leather piston cup in the Pista, for example, needs only an occasional dab of grease to keep it lubricated and pumping, and the rubber seal in the brass head is similarly easy to service. Moreover, replacement parts are available all over the world. It is almost impossible to find a bike shop that does not carry service parts for Silca pumps.
If you want the best pump and donít want to keep buying pumps year after year, there is only one choice for you: Silca. Beautiful Italian styling is the bonus.
