The Cyclocross forum has one of these, but aside from the Pay It Forward thread (which I have used), there is no similar thread here in Commuting. I would think a thread like this might be helpful, so hopefully the mods won't take issue with it. There are things that are not for donation, nor are they for sale - just trade.

That being said, can someone please sticky this thread?

I have a set of flat bar 'Bar Mitts' for cold weather riding I'd like to trade for a drop bar set of Bar Mitts.
