Hubs fall into one of two categories:
Splined or non splined. In general splined hubs are much stronger and
usually have stronger cranks too. They are also far more expensive.
Some standard hub replacement options are as follows:
NON SPLINED
(All hubs listed below use bearings with an outside diameter of 40mm and
use Japanese Industry square tapers)
-Standard chrome taiwanese hub Cheap, nasty and easily bent, or
sheared through. Flange to flange distance is narrower than others.
Crank attaches via nut that screws on to the axle
-Suzue hub. Good quality Japanese hub that ships on unicycles like
Miyata. Will stand a fair bit of abuse but still possible to shear
through the axle. Crank attaches via nut that screws on to the axle.
-Unicycle.com Chromo hub. Tested as stronger than the suzue hub. Crank
attaches via bolt that screws into the axle.
If you go with any of the above replacements you will need to find some
good cranks. These tend to be very expensive and still likely to break.
Aluminium cranks usually last the longest but have a tendency to need
continuous tightening. Kooka make some good cranks for tapered axles.
SPLINED (generally more splines = better)
-Profile hub, 48 splined hub made by profile racing. Uses 40mm or 42mm
bearings. Recognized as virtually bomb proof. Very good quality but
very expensive. They come with a lifetime warranty. Good choice of
crank lengths too.
-KH/Onza hub, a new hub (32 or 36 spline I think) resulting from a
collaboration between Kris Holm, Onza and with input from Roger Davies.
This could be the new standard in unicycle hubs and may be an
improvement on Profile.
-Onza hub (old style). 36 spline hub made by onza. Some early
versions had problems with slop. Long since sorted out I believe. Uses
42mm bearings.
-KH hub (old style). 8 splines and uses 42mm bearings. Is has been the
standard on KH unicycles until now. Again a number have had axle slop
problems. This can be fixed and their are plenty of threads on how to
do so on rsu.
-QuaX, German brand with 10 splines. Ships as standard on their offroad
unicycles.
