The tapered headset is designed to fit frames which are sized to accept integral 1 1/8" top cup and 1.5" integral bottom cups, where the fork steerer has a 1.5 crown and a 1 1/8" top. The 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.
All headsets come complete with the Head Doctor Ahead cap and expander set. 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 resist corrosion - a real advantage over a conventional steel bearing.
Can be used with 1 1/8" fork steerers with the Hope conversion crown HOP127481, which has to be purchased separately.
