I just got a crazy idea. Someone was bragging to me the other day that their campy was so rebuildable, and when they wanted to go from 8 to 9 speed or 9 to 10 speed (I forgot which...I was already defensive feeling about them throttling my 105 components, and I wasn't really listening) they just had to order a small cog, and with a few hours of dissaembling and reassembling, they were able to use their old 8 or 9 speed shifters with their new 9 or 10 speed drivetrain.
now here is the crazy part. what if a third party were to make a little cog thing that allowed it to work with shimano? that way people that like the hand shape and function of the ergo shifter could use the cheaper and more available shimano components? enh? I got an idea there, eh?
ok, now you can tell me all the reasons why it can't be done. go ahead, I can take it. bring it on.
