I quit using this handlebar bag because the zipper broke. My ride quality improved tremendously!
If you use this bag ($10 Bell walmart zipper bag) , put a piece of broom handle in the bag, and run steel hose clamps through the bag, around the bars. The velcro tabs will tear off!
This mirror is good enough to use with the weight of the hose on the stalk, but it still vibrates a lot. I would like a better mirror. Its really good for plain bicycles though.
