Thank you. There's no way I'd put 105s on a commuting bike though. Maybe that though will change one day when I have more money to spend, but for now I feel like 105s are too nice to be used on a commuting bike. My current commuter has Soras, so almost anything will be an upgrade. I'm not saying they don't shift well (they do), but I can definitely tell the difference between them and my 105 bike. (It could also be that the 105 bike has very many fewer miles than the commuter bike, who knows.)
