The second generation of the Tri Cage by Topeak has been redesigned to have a sleeker overall appearance. It is specifically designed for saddle carrier mounting. The addition of an elastic halo enhances the stability and practicality of the forward-release design, ensuring a secure hold and ease of use. This Tri Cage has also been equipped with support for the Ninja+ system, allowing you to combine it with desired accessories for a customized setup. The cage is made of engineering grade polymer and fits standard water bottles. It can be mounted using Topeak Tri-BackUp hydration mounts or other rear hydration mounting systems. One of its key features is the water bottle guide design, which ensures that the bottle stays securely in place. The dimensions of the Tri Cage 2 are 8.3 x 7.9 x 15.2cm and it weighs just 48g. So, it is lightweight and compact, making it a great addition to your cycling gear.
