I just bought a new bike and I am looking to upgrade my wheels ASAP. I've been really interested in both the 101's and the SL's BUT based on their price (and weight) I've recently been considering the Speed Dreams. A lot of the reviews on the Speed Dream are older so I was hoping that I could get a recent update on the SD's and get everyone's feedback on these compared to the Zipp's and K's. I'm looking for a lightweight everyday trainer that is pretty bombproof. I really apprecaite it!
