I have a Shimano Ultegra shifter lever on my road bike and need a good mirror. I really like Mirrycle that attaches to the shifter lever. I have only been able to find a mirror that attaches to the end of the drop handlebar and it keeps getting bumped and needs readjustment. Does anyone know of a good mirror that attaches to the brake hood of a Shimano Ultegra shifter lever? Thanks!
