I am looking for a 165 mm crankset for my wife. She is currently using Dura ace 7800 and would like something with a narrower Q factor. Lighter would be nice too.

Sheldon has 'em

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.

Stronglight and TA

Both Stronglight and TA make 165mm cranks (TA even makes a 167.5mm). Both offer cranks with square taper and Octalink mounting options.

xxcycle.com has wide range of TA and Stronglight cranks.
