Kind of a hijack, but are you going to ride your mtb fixed? On trails?
Do people really do that?
I could imagine riding a single speed mtb, even though I have never done it. It would actually be fun and cool, I'm sure. On the trail, I seldom use more than maybe 3-4 gears...hell maybe not even that.
But the thing about going fixie is that you really don't have a ton of control over when your pedals are down and what might be in the way.
Granted, I'm a bit of a fixie newb, but I can't imagine how hard that must be!
