Here's some pictures of the very first set of Ras Customs wheels. Granted they aren't completely mine, but they do prove the concept.
I later realised I should have got the weight of the complete wheel, but just as a comparison here is the weights of the original wheel, and the parts that replaced it.
The wheels proved to be very easy to mount, about the same, if not easier than the 'normal' style beadlock. Best part though is it will fit about about 49mm knuckle weights for even more weight under the axle.
