The journal bearing system is designed
to
offer
incredible strength and long life with
very minimal maintenance. Standard bearings
are designed with high-speed rotation in mind ( like a skateboard
wheel or a drill motor ).
The journal bearing we use has a purpose of holding a very
tight tolerance along with carrying a load much greater than that
produced by a bicycle frame. We feel that these two attributes are
essential to a great riding xc/trail bike. Making it a dependable
system even after countless miles of abuse.
The rear of our frames are often praised for how stiff they are
laterally and how well they track through the roots, ruts, and rocks
encountered on a xc/trail mountain bike, where pedaling through
diverse terrain is a constant. Since a bearing found in a bike pivot
never makes a full rotation, you rely on two maybe three of the
balls in the cartridge to carry the entire load and pressures gener-
ated by the rider. Over time this is what creates that "crunchy" feel
or "squeaky" sounds.
Standard bearings are also made of steel, which rusts over time
and is very susceptible to the environment, where as our journal
bearing system uses kevlar composites and hard anodized alumi-
num which is lighter in weight as well. So long lasting, tight toler-
ance, less weight and incredible load bearing capabilities are why
we have chosen to stick with journal bearings on our Sultan and
Burner trail mountain bikes.

TR44/52
The TR44/52 bottom headset
features a 1.5” traditional
external cup and bearing
with a 44mm diameter
insertion sleeve. When mated
with a typical ZeroStack™ top
headset the combination
allows the user to install a
1.5” to 1-1/8” tapered
steerer-tube fork into a
straight 44mm ZeroStack™
style head-tube.
Available Models:
40.TR44/52*
110.TR44/52 *
*Bottom headset only

The 44 Headtube:
This head tube is perfectly sized to work with a tapered
steerer fork and the new TR44 lower head set bearing from Cane
Creek. Stiffness gains of up to 20% can be had with a tapered
steerer fork. With the upper bearing bore now at 44mm, the rider
has the ability to run a ZeroStack headset on top. This setup will
lower the hand position up to 10mm for more control on steep
climbs and fast descents, where front end traction is enhanced
through transferring the riders weight over the handle bar. Our
‘just right’ head tube design allows for the biggest bearing size on
the bottom for a long head set life.
