Allen 900B Tension Bar Bicycle Cross-bar Adaptor

If you have a bike rack that has one or more support arms, and your bicycle is secured by being tied down and hung from those arms by its frame, then having a horizontal top tube makes the whole procedure a lot simpler.
Some bicycle frames, such as those designed for women or children, do not include a horizontal crossbar. Additionally, frames that have interesting shapes and are equipped with full suspension may often make it difficult to load such bicycles in a secure and safe manner.

It does not matter what kind of frames your bicycles have; you must always ensure that they are loaded in a safe and secure manner.

Installing a cross-bar adapter on your bike, which produces a solid top tube, makes it possible for the weight to hang more readily and produces a strong, secure load. This is the ideal option.

The Allen tension bar attachment is intended to be compatible with bicycles that have a distance ranging from 16 inches to 27 inches between the stem and the seat post.
