Single rear systems are very popular these days, but the one problem with them is finding a way to store your repair kit. Not anymore: XLAB has designed the 1st aerodynamic repair storage bag for these systems. This patent-pending design looks compact & sleek, but at the same time will carry a great deal of essential repair tools. It fits around the bottle cage on all metal XLAB single rear systems by simply using the two bottle cage holes. Additionally the AERO POUCH 300 actually helps the drag behind you by collecting the air into a smooth airflow.
