Portaborraccia per bottiglia d'acqua

Snapped this onto my cruiser and it grips my bottle tight even over bumpy pavement. Fits a standard bottle just fine and hasn't rattled loose once in a month of rides.

The quick release is what sold me—I can grab my bottle one-handed at a stoplight without wrestling with the cage. Snapped right onto my folding bike's frame and the bottle hasn't budged once on bumpy paths.
