About this item

  • 【EXTEND YOUR HYDRATION CAPACITY!】This rear bike bottle cage mount is designed for cyclists who need extra hydration on long rides. With 3 mounting points, you can install two water bottles simultaneously - either on the sides or behind the saddle. Perfect for road bikes, mountain bikes, and triathlon bikes, it’s the ultimate solution for staying hydrated during your ride.
  • 【LIGHTWEIGHT & DURABLE CONSTRUCTION】Crafted from high-strength PA nylon, this mount weighs only 84g, making it both lightweight and durable. Its weather-resistant design ensures your bottles stay secure in any condition, whether you're riding in rain or shine. Enjoy a sturdy and reliable mount without adding unnecessary weight to your bike.
  • 【EASY INSTALLATION WITH UNIVERSAL FIT】Installing this mount is quick and hassle-free! Simply attach it to your saddle rails using the included non-slip screws and washers. Note: Your saddle rails must have at least 1cm of clearance for proper installation. Compatible with most road, mountain, and triathlon bikes, it’s a versatile addition to any cycling setup.
  • 【DOUBLE THE STORAGE, DOUBLE THE CONVENIENCE】This mount isn’t just for water bottles! It also features additional mounting points for saddlebags, allowing you to carry essential tools, CO2 cartridges, or other accessories alongside your hydration.

Used this on a 10-mile trail. The adjustable straps stayed secure, and the key ring kept my keys from jingling. No bulk, just pure convenience.

Fits my work ID, earbuds, and even a small snack. The buckle is easy to adjust, and the design doesn’t scream "tactical gear." Simple and functional!
