The DK Chamberlain Top Load Stem at J&R Bicycles is a high-quality stem that is CNC machined from 6061-T6 aluminum for maximum strength and minimal weight. Further weight reduction is built into the design with a center pilot bore which also adds durability and the offset pinch slot allows for more threads with improved clamping action. Hardened steel bolts keep everything nice and secure.
