As you might have worked out by now, headsets are a bit of a minefield! Integrated, integral, reducers, dimensions and types all contribute to confusing the situation. Don’t panic! We have now made top and bottom cups available separately allowing our headsets to fit almost any frame and fork combination. Hopefully this brochure will help you through choosing the right headset for your bike.A couple of things to remember though - we don’t necessarily do a headset to fit your bike! We have 4 ‘off the shelf’ combinations and a further 18 ‘Pick n Mix’ options. There are other styles, types and fittings out there. The first thing to remember is that you need accurate dimensions if you are at all unsure of what type you need.The second point to remember is that unfortunately there is no ‘standard’ - OK, we have the dimension 1 1/8 inch, which covers the majority of headsets now, but as far as Integral, integrated etc... these are simply terms used by different manufacturers to determine what they consider that style to be. Measure, check and measure again!One thing that is common throughout our range is the quality of materials used to manufacture them, here in our Barnoldswick Factory, the quality of the custom made stainless steel bearings and the time taken to hand assemble each and every one before it leaves, on it’s way to you!Our traditional headset is made to fit standard frames and 1 1/8 inch fork steerers. They include 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.The integral headset is made to fit low stack 1 1/8 inch frames (please check drawings for exact sizing). They include 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.The integrated headset is made to fit in 1 1/8 inch frames where the bearings fit directly into the frame. They include custom made stainless steel bearings (which are replaceable). The taper ring and crown race (which is split for easy installation and removal) are all machined from 2014 T6 aluminium.The tapered headset is designed to fit frames which are sized to accept integral 1 1/8 inch top cup and 1.5 inch integral bottom cups, where the fork steerer has a 1.5 crown and a 1 1/8 inch top. It is also possible to fit a standard 1 1/8 inch steerer using an additional conversion crown. The headsets include 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. All off the shelf headsets come complete with the Hed Doctor. Sealing is achieved through an adjustable taper ring cover and integrated rubber seal.The bearings also incorporate their own sealing, and being made from stainless steel to resist corrosion - a real advantage over a conventional steel bearing.
