The lezyne Flow Cage Side Load is a lightweight Composite Matrix bottle cage. It is designed on a way so that the bottle can be picked from both left en right side. Many types of bottles fit into this cage (not only the Lezyne Bottle). Also, if you are driving over rough terrain this cage will keep your bottle in place. Thanks to the special design and oval mounting holes this cage is ideal for compact frames with little space for a bottle cage.
