Much like the original Profile Racing BMX cranks but tougher. The Column Cranks feature thicker arms and a 22mm instead of the normal 19mm. The Column cranks are only able to be used with 22mm spline drives sprockets. The best sprocket to use would be Profile's Galaxy Sprocket. The arms are made if 4130 tubular chromoly and the spindle is Gun Drilled Hollow (GDH) to help save some weight. If you are a little hard on stuff these cranks may be just right for you.
