Hope Head Doctor Headset AdjustersIf you want your regular headset tightening and adjustments to be a thing of the past, then the Head Doctor is for you. Hope has made it from anodised aluminium with laser-etched graphics for a premium look. Its expander bung replaces the traditional "star nut" design for a safer hold with more even clamping force inside your fork’s steerer tube.When you install it, two aluminium wedges simply pull together and expand inside any 1.1/8 steerer giving you a solid thread to pull the stem down. Sounds simple? It is.Features: Material: Laser etched, anodised 2014 T6 Aluminium Expandable to 26.6mm Designed to fit 1 1/8" Aluminium steerer tubes only Compatible with most brands of 1.1/8" headsets Laser-etched top cap Even loading in steerer due to full diameter expander wedge Replaces "star nut" design Not suitable for Carbon or Steel steerer tubes Weight: 29gPlease Note: Before use, take apart and grease all of the internal threads and surfaces that have to slide against one another (NOT the surface that will touch the inside of the steerer), failure to do this will make it feel tight before it is. This makes it tempting to tighten even more and as this is a lightweight alloy bolt, it will snap if over tightened.
