Topeak Modula Cage EX

The cage features a simple sliding base and an adjustable arm that allows you to expand or contract the diameter. You can easily set it to fit everything from standard cycling water bottles to larger insulated containers or even smaller soda bottles.

Yes, the adjustable design is engineered to create a snug, tensioned fit around your bottle. While it is not a dedicated mountain bike cage designed for extreme downhill riding, it provides a secure hold for road, gravel, and commuting use.

At just 52 grams, the Modula Cage EX is quite lightweight. It is designed to be unobtrusive and won't noticeably affect your bike's handling or overall weight.

It uses standard mounting points, meaning it will fit almost any bicycle frame equipped with standard water bottle cage braze-ons. If your bike has the two holes on the down tube or seat tube, this cage will mount right up.

Absolutely. It is fully compatible with standard cycling bottles, but its primary advantage is the ability to switch to different bottle types if you prefer using a disposable plastic bottle or a larger insulated container on different rides.
