The Lezyne Pod Caddy QR S is the ultimate seat bag. Easy to use, aerodynamic, and unobtrusive. You'll forget it's there until you need to change a tube.
Made from semi-rigid, molded EVA foam, the Pod Caddy QR's clamshell design allows unfettered access to it's cargo—unclick it from the saddle clamp, and it opens up wide so you can see everything in it. An internal mesh divider provides an extra level of organization.
Since it's only contact point is the saddle rail clamp, the Pod Caddy won't slip or wear out from rubbing against your seatpost. Removing the Pod Caddy is a fast and simple affair; simply press the quick-release lever and slide the Caddy out from under your saddle.
