So, not only has The Mainiac just told me he’s back on a bike and itching to ride trails, but he also let me know he’s cranking out these sweet Pumpa Knuck stems along with his ever popular Quad Saw sprockets. He’s even offering custom engraving on them! The Pumpa Knucks have a 51.5mm reach, 25.2mm rise and they sell for a very respectable $60 for raw or $65 for black or green anodized. Add $25 if you want custom engraving on the stem cap. This shit is rad and I can see these knocking Credence/S&M stems off of bikes of the woodland folk across the world. The DRG Machine Store is where to get one!
