Derrick has been dialing away up in Maine on his new stem and he’s got both the name and the specs locked in. The “Pumpa Knuck” stem is made from CNC machined 6061-T6 billet aluminum and features a 51.5mm reach, 25.2mm rise and comes with black oxide treated class 12.9 alloy steel bolts. Raw, black anodized and green anodized are your color choices, and of course custom engraving is an option. Raw stems will set you back $60, add $5 more for anodized stems, and another $25 if you want custom engraving. They’re available now for pre-order, and that’s the only way to go about it if you want to get your dirty little hands on one. Snag one HERE!
