As other have already stated, mono's are no problem on the street. The big pain, literally, is if you run the bars with preload in them. I have everything Calvert offers; bars, monos, 90/10's and ranchos. I drive the car the same way I race it. Stop and go traffic, to and from work, always the same. I do have preload in the bars, so it rides about like a 1 ton truck.
