BSD's Stacked Stem is a perfect example of simplicity and rugged build quality. A full 6061-T6 aluminium, CNC machined top load style that's built solid with additional machining internally to reduce weight. Six solid allen bolts and a debossed BSD logo on the top plate complete this minimal design. ###section### Product Specs TYPE: Top Load REACH: 50mm RISE: 33mm CLAMPING DIAMETER: 22.2mm WEIGHT: 312g (112oz) Colour: Black, Polished
