The new 31.8 Impact stem has a 45-degree top-load design for BMX racing and freestyle. Available in 48-, 53- and 60-millimeter extensions, the stems are cold forged from the highest quality 6061-T6 aluminum then CNC machined to refine the shape and further reduce weight. Lighter than many traditional 22.2 Ø the Impact 31.8’s open design keeps weight low, while maintaining plenty of strength and the oversize 31.8 Ø clamp ensures that your bars stay put. Available in anodized red, blue, gold and black with laser-etched graphics. Use the Impact 31.8 with the BOX Maximus bars for maximum gate pull. Meets or exceeds ENBMX standards. 48mm-PX-ST144831T: 242 grams/8.5 ounces 53mm-PX-ST145331T: 250 grams/8.9 ounces 60mm-PX-ST146031T: 264 grams/9.3 ounces Stack height 30.5mm
