With wakes being bigger and better these days, Ronix figured they should create a board that will perform to the new generation of progressive riding. This all new Ronix Bill ATR Wakeboard is faster than all the Bill boards from the past. It sits higher on top of the water, giving it more contact with the water than any other Ronix board and pushes the tail up to decrease resistance. Also, with more top water momentum, the Bill ATR allows you to have more stamina and energy to perform. Blended continuous rocker gives you faster glide speed and bigger pop. Mod Pour core is ultra stiff, lightweight, and super saucy. Sintered base remains durable on the rails. Bill ATR 130: 51.2"L x 16.5"W. For riders up to 160 lbs. Bill ATR 135: 53.1"L x 16.6"W. For riders up to 175 lbs. Bill ATR 140: 55.1"L x 16.8"W. For riders up to 200 lbs. Bill ATR 145: 57.1"L x 16.9"W. For riders over 175 lbs.
