Doubles, triples, Ultegra, 105, Sora, Sugino... lots of choices.
I just saw a presentation by Trek Marketing on how they are going to pitch their Women Specific Design bikes. Yeah.... because women tend to be shorter, and need smaller bikes with shorter top tubes and a more upright position, with narrower bars and short reach brakes... HEY! Swap out the bars, and I bet it would be a closer fit for me than what they pop out of the molds for men. Nobody said anything about crank arms... but it's a big screw-up if they don't offer shorter crank arms, too.
