nel-E-nel on April 18, 2026 5:31 pm From what I could find on the Cannondale site, looks like a gear storage mount: [https://www.cannondale.com/en-us/bikes/road/gravel/topstone-carbon/topstone-carbon-2-lefty/2022](https://www.cannondale.com/en-us/bikes/road/gravel/topstone-carbon/topstone-carbon-2-lefty/2022) I’m guessing you can thread voile straps through those slots and secure stuff to the mount.
