Could it be a difference in industry. I am not a xc guy at all, even when riding xc. 90% of the people I know don't use clipless and the ones that do race dh. But 0% use flippy shifters as, besides the shifting problem,you break one (which btw is common on a dh course) its 400 cdn to replace.

Maybe in the world of xc, but I don't see it catching on here. I have yet to meet anyone who likes it except convert roadies. And the pros that are sponsored by the system, only run it in vids and pull it off to really ride (similar to rebadging a frame so they don't have to ride ellsworth for example)
