Outlaw vs Iodine – £1 per gram!
It doesnt seem to be anywhere on the internet so here are some UNOFFICIAL weights for the excellent bargin azonic outlaw wheelset:

FRONT W/O CONVERSION KIT = 1111g or 2 lbs 11.2 oz.
REAR W/O SKEWER = 1315.4g or 2 lbs 14.4 oz.
CONVERSION KIT = 113g or 4 oz.
By comparison the beautiful Crank Brothers Iodine Wheelset (below) weighs in at 870g front and 995g rear – a total of 1865g compared to the equivalent Outlaws 2426.4g!

I guess that is what the extra £550 buys you… 561.4g of weight reduction.
Pretty much the equation goes spend an extra £ for evey g you loose!
