Details

The Impact is Promax's top-load BMX stem. They come in 48-, 53-, and 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.

- Weight: 9.8oz.
- Stack height: 30.5mm
