I was riding a men's hybrid for a while, and I always had aches and pains.

Last year, I bought a Cannondale R1000 Fem, their version of WSD. I loved it so much, I just bought another one!

When I was shopping, I really looked at a Trek too, but I seemed to be in between their sizes, and the Cannondale was just right. Someone else mentioned that when you find the 'one', you just know it.
