The cryro- treatment affects the metal micro sturcture (grain), sort of a stress relieving, which makes the piece stronger. Racers, both bike and car, have been doing this for some time now.
And ol' Falicon is a top notch company! I contacted them some months ago, about stroker cranks for Triumph twins, and found out they do a welded stroker deal. Now Wiseco has pistons for just such a stroker crank.
Michael, you're going first class!
