The trousers clip is designed to prevent the bottom of the trousers from becoming caught in the chain or crank mechanism， and from being covered in oil and dirt. We recommend this trousers clip can also be used as a wrist strap， which are also more securely fastened to the leg and often larger， providing a greater visibility benefit.
