Rode 2007 R3 (49 cm) for over two years now and have never liked the fact that there is toe overlap on this bike. Have I ever gone down due this? No. But, you would think with a slogan like 'Enjoy. Engineering.' that they would not have this problem. They obviously recognize it, because the RS in this size is now offered with 650cc wheels. I just purchased a new '09 Tarmac Pro SL (R3 is now in RBR classifieds) virtually the same dimensions and no toe overlap. Overall, I liked the R3 a lot, a little sketchy on descents, and am expecting the Pro SL to be just as smooth, but better engineered. Any smaller riders have these concerns?
