Add hydration capability to any bike—with or without bottle cage mounts—thanks to the innovative Tern Bossless Bottle Cage. Designed with flexibility and practicality in mind, this accessory ensures you stay hydrated on city rides, commuting trips, or longer adventures.
-
Dimensions & Format
The cage measures approximately 145 mm × 90 mm × 73 mm, compact enough to attach to most frame tubes or posts without protruding awkwardly. -
Material & Durability
Crafted from polycarbonate, the cage is strong yet lightweight, offering scratch-free handling for stainless steel bottles, while the rubber base prevents unwanted movement or rattling during rides. -
Weight
Weighing in at just ~72 g per set, the cage won’t add noticeable bulk to your bike, maintaining overall ride agility. -
Mounting Versatility
Its Velcro fastening system allows it to be mounted securely onto seatposts, handleposts, seat tubes, head tubes, or down tubes with diameters ranging from 22 mm to 41 mm—no brazed-on bosses or eyelets required. -
Bottle Compatibility
The spring-loaded cage arms accommodate bottles from 63 mm to 73 mm in diameter, keeping small or large bottles snug and rattle-free.
Usage & Care Instructions
-
Installation
Wrap the Velcro strap around your chosen tube (22–41 mm in diameter) and tighten until the cage sits firmly, but without overtightening that could damage the tube or strap. -
Inserting Bottles
Simply slide your bottle (63–73 mm diameter) into the cage—the spring-loaded arms secure it in place gently yet firmly. -
Surface Protection
The rubber base ensures your bottle or bike frame remains scratch-free during rides, particularly with stainless steel bottles. -
Maintenance
Rinse off dirt or sweat after rides using mild soapy water. Wipe the rubber base clean and allow it to air-dry—this prevents grit buildup and maintains the Velcro’s stickiness.
Precautions
-
Ensure Proper Fit
Make sure the cage is tightly secured and doesn’t shift during bumpy rides—re-tighten the Velcro if needed before each ride. -
Avoid Overloading
Don’t try to force oversized bottles into the cage; excessively large or heavy bottles might deform the polycarbonate. -
Secure Folding
If used on folding bikes, ensure the strap doesn’t obstruct folding joints when collapsed—tuck it neatly during storage or transport.
