It hasn't happened yet, but this thread sure is making me think about what I'm going to say. I just got my bike in December and I'm doing a short group ride on Sunday. I figure I'll hear it then. The biggest surprise to me is that the boost doesn't do all the work. For some reason I thought it would do it all when I had it on. To me, the boost seems like I am riding with a stiff wind behind me.
