The Australian OGKs were never as good as the UK ones Marty ... they reacted better to high air moisture content  8)

At the end of the day no mag wheel stood the test of time - I've just had a bunch of new schoolers asking why I'm still rocking 'mags' when 'spokes iz lighter and better innit'

Bob_Acid:
If OGK's are made from Nylon too it stands to reason they won't straighten in the freezer either.  Give it a go and let us know otherwise go with what Glen said.   :daumenhoch:

Dupont GT, I Think this is a thermo- set plastic. 

'The curing process transforms the resin into a plastic by a cross-linking process. Energy and/or catalysts are added that cause the molecular chains to react at chemically active sites (unsaturated or epoxy sites, for example), linking into a rigid, 3-D structure. The cross-linking process forms a molecule with a larger molecular weight, resulting in a material with a higher melting point. During the reaction, the molecular weight has increased to a point so that the melting point is higher than the surrounding ambient temperature, the material forms into a solid material.
Uncontrolled reheating of the material results in reaching the decomposition temperature before the melting point is obtained. Therefore, a thermoset material cannot be melted and re-shaped after it is cured. This implies that thermosets cannot be recycled, except as filler material'. 

Be careful if you Apply heat.  don't go to hot a hair drier should suffice.  You get to warm and the wheels are toast...
