## Description

Review: Makes it easy to other family members to use each other's bikes. - I have no idea why 'light weight' is a criteria, but I guess it is light enough. Anyway, I wanted to make it so that any family member could ride any bike they want. We are all different sizes, so these seat adjusters work so that we can call change seat heights when we are using each other's bikes. I like the different colors - nice touch.
Review: Fits a regular bike. - It’s hard to tell the fit online. I have a couple regular bikes. This fits perfectly.
