I really like Ergon grips. Am considering switching to Grip Shift, but am not confident I can use my Ergon grips with Grip Shift. The Ergons are clamp-on style and the Grip Shift is "Jaws" technology. I'm not clear from the web site if Ergons would work on Grip Shift. Would it be pretty straightforward to remove the non-shift part of each Grip Shift and replace the grips?
