to turn adjusting clamp.
3. Once the adjusting clamp is in position, use a 2.5mm hex wrench to tighten
the adjusting clamp hex bolt to 10 inch-pounds.
4. Check for play or binding and readjust if needed.
Note: Correct adjustment of the rear hub is necessary for proper engagement of the
RingDrive.
If the hub is run loose, the RingDrive may not engage properly and could
lead to permanent damage of the internal parts. *Do not ride hub without the proper
preload adjustment
ISO Single Speed rear hubs
(see Figure 9)
The ISO Single Speed rear hub uses our Single Speed one piece axle design. For
disassembly, reassembly and adjustment information, follow the one piece axle in-
structions on pages on pages 10 and 11 of this manual.
Cogs
(see Figure 10)
Chris King Single Speed hubs use a cassette -style cog mounting system.
Special splines and lock rings have been designed to accept our premium
quality stainless steel cogs. They are available in sizes from 12t to 20t.
Cogs can easily be removed and changed using standard cassette tools.
Chain
Chris King cogs are designed to be used with an 8-speed or 3/32” chain
only.
Chain line
Setting the single speed cog to the proper chain line is essential to achiev-
ing the best performance from a bicycle’s drivetrain. Our Single Speed rear hub allows
for center-to-cog chainlines of 45, 50 and 55mm. To determine the proper chainline
on a single speed bicycle with 135mm rear dropout spacing, follow these instructions:
1. D eter mine the front chain r ing position by measur ing the distance from the
exact middle of the bottom bracket shell to the front chainring.
2. Locate the middle point of the rear ISO Single Speed hub by measuring 67.5mm
from the inside face of the rear drop out to the middle of the hub.
3. From that middle point, use the front chain ring position measurement found
in step 1, and measure from the hub center out to the driveshell.
4. This is the point on the driveshell where the rear single speed cog should be
