Changing 42 to 39 on Triple Crank
Hello:
On my road bike I've got a Cannondale EX (2001) triple crank with 52,42 and granny chainrings.
I do not use the granny and want to swap the 42t to a 39t inorder to reduce redundant gear ratios (and get some lower ratios for the hills).
I am not sure which 39T shimano (or equiv) chainrings I need as there appear to be two versions with diff pick-up pin locations.
Would there be any benefit to getting a 53T ring at the same time (other than taller gearing)?
FYI I plan to buy 105 or Ultegra rings (or equiv), Unless someone can convince to me that DuraAce ring are worth the cash.
Thanks,
Matt

I cannot speak regarding Shimano, but I have found no significant difference between Campag.'s "A" and "B" rings.
