Hope Headset Brochure - 18 Bikes

HEADSET ANATOMY
HOPE OFF THE SHELF HEADSETS
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! Hopefully this booklet 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 one
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”, 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!

All headsets are built in this order. If in doubt, call the

Our conventional headset is made to fit
standard frames and 1 1/8” 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” 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” 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” top
cup and 1.5” integral bottom cups, where the
fork steerer has a 1.5 crown and a 1 1/8” top.
It is also possible to fit a standard 1 1/8” 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 resist corrosion - a real advantage over a
conventional steel bearing.

This could be 1 1/8” or 1.5”. The cups press
into the frame and the bearings sit outside of
the frame.
This could be 1 1/8” or 1.5” (although there
are 2 dimensions used for this size). The cups
press into the frame and the bearings sit within
the frame.
This is 1 1/8”. There are no cups, the bearings
either sit on loose seats or directly into the
frame. The bearings sit within the frame.
