Okay, after falling over 5x yesterday, banged up both sides of my body and severly sprained my right wrist, NOW im returning them for credit on a new pair of shimanos. IM thinking about the 536's. The 515's look like they belong on road bikes although they are also nice. What do you guys think? Im not going to buy a pair b/c they are cheap anymore. I did it and i paid the price.
