I rode a Trek 1000, 50 CM, for 2 years just fine. Many of my rides were an average of 40-60 miles.

I am 5'4" with a long torso and short legs.

It's a good solid bike, and just because you are a women does't mean you necessarily need a WSD bike.

I recently bought (well, got it as a gift) a Specialized Tarmac Expert, 49 CM. Fits me just fine too.
