WHEN THE GOING GETS ROUGH The C.I.M. Cage is made to keep a firm grip on your water bottle regardless of the road surface or trail condition. Using long carbon fiber reinforced polyamide, the injection molded cage has a tuned grip and full-contact rails to prevent bottle creep and ejection. While at first glance this cage might seem like just any other bottle cage, all considerations have been made to ensure that the C.I.M. Cage will hold your bottle, no matter how rough the going gets. At 31 grams, the C.I.M. Cage is lightweight while still doing its job. Made in Utah.
