Has anyone used or currently use any of the Ergon Grip products? I've seen them advertised in Magazines and on Fatty's blog. I understand the concept behind them, but was wondering if anyone had any "real world" experience that they could "share with the rest of the class". I tend to get numbness in my fingers after longer rides. Now I realize that is mostly due to the fact that I'm 6'-4" and weigh 280 lbs, and that my hands are supporting my entire upper body (which is the majority of my 280 lbs). It just stands to reason that a grip with a larger surface area would distribute my weight a little differently. Anyway, if anyone has any thoughts or comments, post away.
