Well...as a brand new Trek WSD Pilot 2.1 owner....(See pots entitled 'I have a new bike') I can tell you I love my 2.1. I'm still getting used to the clipless pedals and to be honest didn't ride either of the other WSD's you mention. This one fit....was the color I wanted and was in my price range. I loved one that was less $$$ but couldn't deal with the color. Gimme black....no pastels, thank you very much. When all things were equal...I went for the 2.1.

Some of the other women on this forum have alot of experience...so I'll defer to them.

Best from Florida...where storms and tornadoes raged all day today. We're ok.
