Description

Promax Impact stems have a 45-degree top-load clamp design for BMX racing and freestyle. Available with 48- and 53-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 (260 grams/9.2 ounces in a 48-mm extension and 265 grams/9.3 ounces in a 53-mm extension), while maintaining plenty of strength and ensuring your bars stay put.
