RIM AN (AM) 20 406x31 VANDAL G69 TCS 36SANDWORM-BK/WH XL sized BMX rim made to be extremely light for its size by use of Alienation`s proprietary G69 material. 4D less chamfering drilling process creates the optimal interface between flange and rim. These rims are designed and drilled for 3 cross specifically - no radial lacing. Each TCS Vandal rim comes with a Veloplug for the unused valve hole (TCS Vandal rim is drilled for both TCS and Schrader). Braking is nearly as good as chrome less the added weight and negative environmental impact through specialized surface coating.
