The Machine Stem from Stranger, CNC machined from a block of 6061-T6 aluminium that results in a stem that means business. It's tough & fairly lightweight with a minimal, recessed top plate. Stranger's logo is debossed into the top cap plate & to keep the overall look clean the stem has a recessed Fork Cap area so the top cap sits flush inside the stem. section Product Specs TYPE: Top Load REACH: 50mm RISE: 30mm CLAMPING DIAMETER: 22.2mm WEIGHT: 305g (10.82oz)
