King does have a stainless steel version of the freehub although its a little heavier. I don't think the AL version will be a problem anyway. Its still pretty damn strong and you don't hear many reports of their al freehub bodies being damaged by cogs in either road or mountain wheels.Nessism said:I'm not a fan of hubs that use an aluminum freehub body because the cogs can (will) dig into the edges of the splines and damage them. This is why Shimano never made an aluminum freehub body until 10 speed - when they made the splines deeper. Of course, if you are using 10 speed, or Campy, nevermind.
