I currently ride a Cannondale F300 mountain bike to commute from home to work that's about 30 mile round trip in the San Fernando Valley located in California. It's fairly flat and doesn't rain much at all. I have a bike set up with lights, extra tube with equipments to change tube, lock, rear rack, avenir panniers, rear pack. I'm interested in getting Arkel T42 panniers to replace my Avenir panniers b/c I hit my heels on the panniers, and it pisses me off. I like how Arkel T42 are adjustable to fit the rack. I was wondering what other equipments you suggest me to get. I want to start riding my bike on weekends too for fun. So, throw me some ideas of things to get. Thanks for reading.
