It's strong enough for downhill use, yet still light enough for cross-country, this Hope Conventional Headset includes custom-made stainless steel bearings (which are replaceable). The cups, taper ring and crown race (which is split for easy installation and removal) are all machined from 2014 T6 aluminium. It is also possible to fit a standard 1.1/8" steerer using an additional conversion crown (sold separately). All Hope headsets come complete with the Head Doctor. This Hope EC34 Headset also has advanced sealing that's achieved through an adjustable taper ring cover and integrated rubber seal. The bearings also incorporate their own sealing and are made from stainless steel to resist corrosion - a real advantage over a conventional steel bearing.
Hope Pick and Mix headset cups and bearings are sold as individual top or bottom components. They are ideal for building up frames with tapered head tubes, converting frames with larger head tubes to fit standard fork steerers or for replacing damaged cups/bearings individually. There are 6 top cup options and 8 bottom cup options to choose from, these are designed to fit modern road and mountain bike frames; older 1” and threaded standards are not included. Hope Pick And Mix Headset cups/bearings are available for three headset standards; External, Integral and Integrated.

The two aluminium wedges of the strong and reliable Hope Head Doctor simply pull together and expand inside any 1.1/8" fork steerer tube, giving you a solid thread to pull the stem down.
Made from tough and durable 2014 aluminium, the four sizes in the Hope Space Doctor Headset spacers pack include two 5mm, one 10mm and one 20mm size. This enables you to run a low and slammed setup (ideal for road racing or cross country (XC) riding) or a more upright setup (ideal for road endurance, all mountain (AM) or enduro riding). The colouring and finish on these custom machined head spacers complement Hope's headsets and stems perfectly.
