Sure, I've been commuting with it, with some heavy rain on Wed and Thurs. Also a longer ride in the nice weather yesterday. Since there is no metal touching except for the non-drive side brace there is no rattle. My main concern was with it staying in place but that hasn't been a problem yet.

I've been tempted to add vinyl or Coroplast sides but one thing stops me. I don't really want the extra surface area exposed to side winds, resulting in extra drag. A minor concern I admit, especially for that bike but still enough to stop me from taking the time for it ...
