From the Nagtroc forums 18 x 9.5 = 6 lbs. Thats light .I think the picture came from a poster on the thread.
So whats the name of the company that makes these ? How durable are they ?
Dymag has been producing Carbon barrel , Magnesium center wheels for a while. I was looking for weights on their site, and the number I found was "as light as 14 lbs".
