The Yak Wheel has a beautiful and VERY rugged machined aluminum wheel and a hard but grippy rubber, 2.5" wide tread. The only complaint with these is that the tread profile isn't 100% flat, and might need to be planed a little bit before use in robotic combat... But as it is, it is still VERY grippy!



This product comes with ABEC 5 bearings included.
