I just started trials biking, as in i ordered my bike and don't have it yet, lol... Im big into bmx and wanted to do trials... I heard about tubeless tires, and i have a couple questions... 1.) Do tubeless tires fit into trials at all? they sound bad ass... 2.) If using a tubeless tire on whatever type of bike you use it on, does it need specific rims? or how does it work?
