Chromoly seems to me a better choice for cranks than aluminum, in that you're dealing with really high stresses, especially at the BB interface, in a pretty tight clearance area. DH and BMX bikes (except for pure race bikes) have mostly gone to chromo cranks for strength reasons.
I'm wondering why noone has come out with lighter weight chromoly cranks. It's been done before: Sweetwings were the lightest cranks ever made (or close to) and bullseye's were legendary, at a pretty reasonable weight. Syncros and McMahon both tried it but were limited by the stupid aluminum tapers that elimated one of the benefots of using chromoly...
So why isn't anyone making a "midweight" chromo crank right now... somewhere around or maybe less weight than the RF Northshores or Hussefelts?
