Saw this on Fat today—the new Quamen LoCal frame, which is "the first frame in the BMX industry to use Cryogenic Engineering."
Apparently it's a process that can be used in tandem with heat treating, although it also works as a stand-alone process.
The frame itself isn't anything to write home about—low top tube, standard angles and dimensions (74.5/13.75/11.5), even a more or less standard weight, four and a quarter pounds. No word of how much it's gonna cost.
Looks like they should have taken the frame off the lawn before initiating the cryogenic process, huh? Hey man, if it's good enough for Walt Disney and Ted Williams's head, I suppose it could be good enough for a street frame. It's a tried and tested process in other disciplines. Heat treat first, then rather than just cool to room temp, cool it WAY down. To below -200 degrees Fahrenheit.
(Of course, if this catches on, companies will start having to come up with cool (haha, get it?) names for their own freezing processes: "Iced Out." "Mr. Frosty." "Otter Pop Tubing." You know, that sort of thing.)
But hey, if you get to actually observe the process, just one word of advice: No matter how good your frame looks, for God's sake don't lick it.
