Don't know if anyone has tried this yet, but the stock grips and bars have always been too small for my hands. The small contact area creates a greater pressure point and the stock grips do not have much cushion for the longer rides. So I had the idea of using tennis racket tape to increase the diameter and provide some extra padding without giving up the "grip" of the stock grip. I bought Prince High Tack Replacement Grip from a sports store and the result is amazing. The new size feels great...the padding is firm but has some give...and there is no slipping with the high tack quality... $6.99 per side!! Clean the stock grips with alcohol and apply - the tape has a sticky backing so it won't move.
