I've seen those, I think they're called the Pro or Limited models. Would be interesting to try one. But I definitely agree on the grip shifters...they work and give the bike cheap indexing, but they really do suck too...

Got my ass handed to me tonight on the fast group ride. They sped up, and I wasn't at all used to my new pedal setup. I bonked out somewhere in the last 10 miles and went into limp home mode. The crazy thing is, even after bonking out, I still covered 27.1 total miles in 1:30:45, putting the average speed right at about 18 mph. I really would like to know what we were doing before I bonked, it could have been well into the 20s. I literally sweated off about five pounds tonight.

Feels good now, but man I thought I was gonna die out there, lol. I really need to get some more time on these pedals so I can build strength with them.
