The Impact is Promax's top-load BMX stem. They come in 48-, 53- and new 60-millimeter extensions and 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. Available in anodized red, blue, gold and matte black with laser-etched graphics. Meets or exceeds ENBMX standards.
