I've been looking at the R3's. I printed out the comparison sheet from the Fulcrum website and it seems that the only difference between the R1 and the R3 is that the R3 has stainless steel rather than aluminum spokes. Which apparently accounts for the R3 wheelset being 55g heavier. Plus, I'd think that steel spokes are more compliant than aluminum.
