1. I need a mirror. I ride in traffic and make lots of left turns.
2. Helmet mirrors do not work for me.
3. I do not want to lose any hand positions.
4. I do not want to feel anything mirror-related under my hands when I ride. In other words, I don't want to know I have a mirror unless I'm looking at it.
5. I ride without gloves.
6. I have bar-end shifters and drop bars.
So far I have not found a product that works for me. May need to DIY. Any ideas?
