Notes Quickly becoming rare on newer bicycles. Principally found on older or city bikes.

Notes Most popular system. 1.5" is newest size. Cannondale was rst to use this, but made a running change to a nal standard with a deeper head tube bore (25.4 mm versus 11 mm ream depth). On Cannon-dales, carefully match stem to steerer diameter, as there may be some nonstandard diameters.

Notes Idea being promoted by Columbus. It combines the simplicity of external cups with a low-prole look. A larger diameter head tube is required than with a traditional threadless headset.

THREADEDDerived from the original 1" diameter head tube

national standards now typically standardized

as follows:

1" JIS standard. JIS (Japanese Industrial Stan-dard) is common on lower-priced bikes from

Japan, Taiwan, and China.

1" Professional (Campagnolo) standard: pre-dominates among aftermarket headsets and

higher-end bikes and framesets. JIS dimen-

sioned bikes can be milled to Professional

standard. The opposite is not true.

118" from the original Tioga design; also used on some tandems and mopeds.

1" from the original Gary Fisher design.

THREADLESS Standard/AheadSet type1" JIS standard.

1" Professional dimensional standard, more common for aftermarket headsets. JIS dimen-

sioned forks and frames can be reamed to Pro-

fessional standard.

118" to Tioga standard.

1" to Gary Fisher standard.

1.5" (One.point.ve): a cooperative standard from Cane Creek, Manitou and others. Cannon-

dale may have been the rst company to use

a 1" head tube. Cannondale initially used

a ream depth of 11 mm, but then changed to

25.4 mm, the same as the cooperative standard.

Cane Creek makes a special headset to convert

Headshox equipped Cannondales to forks with

a 1 18" steerer. Cannondale has also used some

nonstandard stem/steerer sizes.

THREADLESS LOW-PROFILE Intellaset/Slimstak1" and 118" Uses conventional external cups, ush to the sides of the head tube. Most com-

mon in Europe. Headset adjustment and stem

attachment follow the same procedures as for

any standard threadless headset. It can be con-

sidered a subset or derivative of the standard

threadless design.

THREADLESS INTEGRATEDBearing cartridges are installed into an enlarged

and specially machined head tube without cups,

achieving the lowest stack height of any design.

This design requires especially good ream con-

centricity and depth control. Headset adjustment

and stem attachment follow the same procedures

as for a standard threadless headset.

1" and 118" Cane Creek standard (mostly 1 18").

1" and 118" Campagnolo Hiddenset standard.

1" and 118" other standard(s), very rare.

THREADLESS SEMI-INTEGRATEDSometimes confused with Integrated; has cups

semi-recessed (and pressed) into and onto the

head tube to achieve a low stack height. Head

tube diameter is large to accommodate the re-

cessed cups. Headset adjustment and stem at-

tachment follow the same procedures as with

any standard threadless headset.

1" and 118" Cane Creek Zero Stack standard (95% of market share, mostly in the 1 18" size).

1" and 118" to various other standards, very rare.

THREADED SEMI-INTEGRATED 1" and 118" New, fairly rare, and mainly on Eu-ropean city bikes. Combines the large diameter

head tube of the semi-integrated type (similar

dimensions) with a threaded steerer tube for

greater stem height adjustability. This type of

headset may be found on some Giant bicycles.

UNUSUAL COMBINATIONSSome bicycles combine a 1" lower stack with

a 1 18" upper stack (e.g., Trek 5900); other bicy-

cles combine a 1" O.D. fork with a 1 18" headset,

using special parts so as to deplete old stock;

some RockShox 1" forks have JIS dimensioned

crown race seats; one titanium Litespeed model

was designed for an integrated headset using

sleeves inserted into the head tube, and there

are yet other unusual combinations. Mostly,

these exceptions and hybrids follow the general

guidelinesthough with a twist. Being aware

of the normal standards should help you cope

more easily.

BMX EXCEPTIONSBMX bicycles typically follow the above stan-

dards, though for the 1" size and mainly on

older bicycles, there is also an increasingly less

common original standard using a 1" diam-

eter steerer tube with 32.7 mm OD cups pressed

into a 32.5 mm ID head tube. Crown race seat OD

is 26.5 mm and crown race ID is 26.4 mm, like

those of the 1" Professional.

CHAPTER 12

HEADSETS

Generally, components are dimensioned with

one-sided tolerances. All of the tolerance range

is in one direction (either larger or smaller)

away from a target or preferred dimension.

The target dimensions generally achieve the

Headset Fit Headset Fit (continued)

minimum desirable press t, with allowances in

the direction of tighter ts. The value given in

bold type is generally the target.

All dimensions are in millimeters unless other-

wise indicated.

Notes Dimensions are

guidelines only. Some situations (e.g. very thick walled steel head tube) may require reduced interference.

Bold values are target values with tolerance ranges falling in the direc-tion of increased interference.

Notes See detailed illus-

trations under each headset type, on the following pages, with many more fit dimensions.

Integrated head-sets have no cups; cartridge bearings are mounted directly to head tube.

Note Information

based on data collected from various fork and headset manufacturers.

For information on bicycles made before 1996, and on older national or brand standards, refer to Sutherlands 6th Edition, page 14-2.

Notes Early Cannondales

using 1.5" headset may have a ream depth of 11 mm. Cane Creek makes some models to fit. It may not be a good idea to ream out the head tube to 25.4 (minimum) depth to fit standard 1.5" headsets, as Cannondale has used some head tubes with an hourglass shape that does not allow for adequate wall thickness with deep reams.

Cane Creek also makes a model to adapt 1.5" to work with 118" forks.

Notes JIS 1" standard

headset can be replaced by Profes-sional 1" after milling the head tube and crown race seat.

Bearing balls in retainers are shown in Notes column as R0 " with 0 = number of balls & " = ball size. If number of balls is unknown, comments show " balls in retainer.

Tip

Loose balls are generic, avoid-ing ordering problems. Ball retainers usu-ally have fewer balls, and lower load capacity. Ball retainers may sometimes be necessary if assembly dif-ficulties prevent loose balls from being correctly positioned.
