these are unique
The power grips for the Fixed gear bike are quite good. My only beef is that it is a bit tough to get into them, especially on the fixed gear bike when your "slip-in" time is greatly restricted. However, I have size 13 shoes which may compound the problem. But they are really nice once you get locked in, and you can wear dress shoes if you must without mucking them up, which is important for me. It is also really easy to release from these, which is critical given the idiotic drivers in Tucson.
