Thanks, It seems that 700s may get pretty close to the front fender edge during a turn...a 650 seems to have only about an inch and half clear..There is a 750 16 mounted on one of my wheels now, so Im guessing that a 700 will work. I think I will go with the Tornels from Summit which are a little less expensive. Ive never had a speedo that wasnt funky anyway. Thanks
