My personal bias would be towards cold-forged. That being said, the White Industries cranks are one of the few CNC'd cranksets I'd consider. I've ranted a bit about cranks in general over on my blog, and much of it is really outside the topic of this list. http://ramblings.cyclofiend.com/?p=399 Pulling some early-90's recollection out of the memory cave (in other words IIRC), depending upon how you spec your billet, you can get some of the benefits of forging. I'm sure some metallurgist will correct me if I'm wrong, but I do recall that you can gain some of the directional benefits within the metal when it the billet gets formed - there may be a die step involved (as well as the various alloys of aluminum). As long as you do your CNC work (or _any_ type of machining) with this in mind, you can minimize the risk of breakage. - Jim -- Jim Edgar cyclofi...@earthlink.net Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Your Photos are needed! - Send them here - http://www.cyclofiend.com/guidelines "I threw one leg over my battle-scarred all-terrain stump-jumper and rode several miles to work.
