Identify the drive side and non-drive side end caps. The non-drive side end cap has gradient marks.
Use a 2 mm hex to loosen the end cap set screw located on the non-drive side end cap. You do •
not need to remove the set screw.
Use your fingers or a insert a 5 mm hex into the drive side end cap and hold it place. Then gently •
rotate the non-drive side end cap clockwise until it bottoms out and stops turning.
Align the zero degree (0°) gradient mark on the non-drive side end cap to a fixed point on the hub. •
Hold the drive side end cap in place and loosen the non-drive side cap by rotating it counter- •
clockwise to the 120 degree gradient mark.
Use a 2 mm hex to • gently tighten the end cap set screw until it bottoms out.
The set screw retains the end cap and helps to prevent unintentional adjustment. Do not force or
over-tighten the set screw; this could cause it to deform or strip the threads.

ADJuSTMenT VeRificATion
Before mounting your wheel on the bike, use your hands to check for a small but noticeable amount of
axial (side-to-side) play in the end caps. This axial play is necessary and correct when the wheel is not
mounted on the bike.
Mount your wheel onto the bike (or in a truing stand) and secure the quick release according the •
manufacturer’s instructions.
Securing the quick release provides the final preload to the hub bearings.
Hold the bike so that the wheel is off the ground. Rotate and hold the wheel so that the valve stem •
is at 90 degrees.
Let go of the wheel. The wheel should rotate freely. If the wheel does not rotate freely, the end caps •
are too tight. Repeat the hub adjustment procedures until the wheel rotates freely.
Set the bike back on the ground. Side load the rim back and forth with your hand and check for •
play at the rim. There should not be any noticeable play. If excessive play is observed, the end
caps are not tight enough. Repeat the hub adjustment procedures and reduce the amount you
loosen the non-drive side end cap by small increments until the wheel still rotates freely and the
rim does not have any noticeable play.
