Promax Impact stems have a 45-degree top-load clamp design for BMX racing and freestyle. Available with 40- and 45-millimeter extensions, they are cold forged from the highest quality 6061-T6 aluminum then CNC machined to refine the shape and further reduce weight. The "open" design keeps weight low, while maintaining plenty of strength and ensuring your bars stay put.
