With a crank that small, what do you intend to run for a cassette, 12-23?
i run 13-29 for climby rides and 13-26 for 'flatter'
most of the riding is in the 'big' ring, so i'm only shifting up and down in the rear.
i may even put a 44 on the front so i'll essentially have a 1x10 setup for most situations... until i head into the mountains or gaps.
i did spin out yesterday @ 46/13 chasing a riding partner. he was running something taller and was smoothly pedaling while i felt like i was descending on my fixed gear. i gave up the chase after about 1/4 - 1/2 mile. on a short social ride it might be fun to have something just a bit taller - but for most of my riding... and for brevets and ld rides in the mountains and hills - 46/30 with 13-29 works well for me. i don't ever see myself 'chasing' coming down a gap... unless someone stole coffee and pastry.
