Involving the Silver and Black best- the afterwards Black versions arrived with nevertheless lighter rotating factors.

The Blacktop does Have got a remarkable gudgeon pin style and design in that it has countersunk finishes which give it a small 3g gain bringing the weight difference a little closer. The gudgeon pins them self are quickly interchangeable.
