Maryellen-
I went from a Trek Hybrid to a Trek Pilot 2.1 WSD this year....and now I'm having trouble getting back to riding my hybrid. If you can get your hands on a Pilot 5.1 WSD try it. It's a terrific bike, I just couldn't afford it. I probably stayed with the Trek line because I love our Trek LBS and their staff.

The seat on my Pilot 2.1 WSD is great, no need to change it out...but my husbands non WSD Pilot 2.1 has a horrible seat, after the first ride he changed to a Terry liberator.

Good luck, and let us know what you get!!
