These are durable tough and rattle free. Easy to take off. I’ve swapped colours around never a problem. These black ones are a satin matte stealthy colour, not shiny. They finish the look on this gold SE BeastMode.

I needed to protect my son’s pants from getting the chain grease on his school uniform when he rides his bike to school. Very easy to install and it works great!
