I love my Ortlieb 40L panniers! So happy they had my favorite color of Orange (plus it’s nice to be seen). They were easy to install as I don’t consider myself mechanically inclined. The first day I rode and used them, I was able to fit $85 in groceries! I made sure to balance both sides and my bike rode like a dream handling all the weight nicely. Be sure to carefully balance your bike when you remove a bag as it may tip to the side with the other bag still on it (gravity). I’m riding more just because of my new bags! May sound silly but true! These panniers are worth every penny!!
