TheHope DH Stemis CNC machined from a solid billet of 2014 T6 aircraft spec aluminium alloy. With the increased demands being placed on these high stress areas, Hope have increased the amount of material in and around the steerer clamp, bar clamp and mid sections to create an incredibly stiff stem for precise, solid steering. The opposing steerer clamp bolts of theDH stem have been increased to 3, again to aid strength and stiffness. The 4 bolt bar clamp (31.8mm oversize only) has a new clamping design, whereby 2 bolts are tightened as a pair and then the second 2 follow - which helps to distribute any stress evenly through the bar.
