Parts and Tools

• ROAM 50/60 = 26 mm width rim tape

• RAIL 50 = 28 mm width rim tape

• Nitrile gloves

• Apron

• Clean, lint-free rags

Tubeless Rim Tape Installation

Install the wheel into a truing stand. Remove any existing rim strips

or rim tape from the rim. Remove the valve stem. Thoroughly clean the rim with isopropyl alcohol and a clean rag. Make sure that the rim is dry and free of alcohol. Spinning the wheel rapidly in the truing stand can help remove alcohol from the spoke holes.

• Wheel truing stand

• Isopropyl alcohol

• Small flashlight

• Small knife

• Scissors

Apply the beginning section of tape between the two spoke holes

that are 180 degrees opposite from the valve stem hole. Press 4-5 inches (10-13 cm) of tape into the channel of the tire bed.

36Tubeless Rim Tape

Apply tension to the tape by rotating the wheel away from you

while rapidly "shaking" the tape from side to side about 2-3 inches (5-8 cm). This will seat the tape into the channel and keep it centered in the rim.

NOTICE

The tubless tape must be seated into the channel to create an adequate seal. If the tape is not seated into the channel, the tire may leak air.

Continue the process of rotating the wheel and shaking the tape

side to side while keeping an even tension on the tape roll until the tape meets the beginning edge of tape from step 2. Overlap the beginning edge with another 12 inches (31 cm) of tape to the wheel.

Cut the tape. Use your ﬁngers or a tire lever to press the leading

edge of tape against the rim. This will help prevent sealant from getting under the tape.

12 in (31 cm)

37Tubeless Rim Tape Installation

Valve Stem Installation

Shine a ﬂashlight through the rim to illuminate the valve stem hole.

Use a small knife to cut the tape from the valve stem hole.

Remove the nut and o-ring from the valve stem. Install the valve

stem into rim.

Install o-ring onto the valve stem.

Install nut onto valve stem and o-ring, with the recessed area toward rim.

Press the valve stem into the channel and hand tighten the nut.
