The Bossless Bottle Cage lets you add a bottle (or three) to any bike—mounts or not. We designed it so Tern bike riders can add extra water bottles to their seatposts or handleposts, but it works just as well on bossless track bikes, under-equipped road bikes, and long-haul tourers.
Velcro fastening system secures the cage without water bottle mounts, bosses, or eyelets
Mounts to any* seatpost, handlepost, seat tube, head tube, or down tube with a diameter of 22 – 41 mm
Sprung cage design snugly grips small and large bottles (63 – 73 mm in diameter) for a rattle-free fit
Grippy rubber base prevents movement during rides
Optimized for stainless steel bottles thanks to non-scratch polycarbonate
