Attaching The Tubular Tire To The Rim - Bontrager WHEEL Owner's Manual

Applying the First Layer of Glue
Follow the glue manufacturer's installation instructions for using their glue, especially
suggested drying times. The first layer of glue on the rim must be very thin and allowed to dry
fully (usually around 24 hours). This first layer is the foundation of the correct attachment of a
tubular tire.
1. Place the wheel in the truing stand.
2. Put on the protective gloves.
3. WIth the acid brush, apply a thin layer of glue to the rim's tire bed, edge to edge, all the way
around the rim (Figure 22).
4. Inflate the tire just until it rolls over and the base tape is exposed (Figure 23).
5. Apply a thin layer of glue to the base tape.
6. Allow the glue to completely dry.
Applying the Second Layer of Glue
1. If it is not already there, place the wheel back in the truing stand.
2. Put on the protective gloves.
3. With the acid brush, apply a second think layer of glue to the rim.
4. Inflate the tire just until it rolls over and the base tape is exposed.
5. Apply a thin layer of glue to the base tape.
6. Allow the glue to completely dry.

Attaching the Tubular Tire to the Rim

Tighten the removeable valve core before gluing the tubular on the rim. When riding, the valve
stem can rattle in a deep section rim. To reduce the chance of noise, prior to this procedure
wrap a layer of electrical tape around the valve stem or apply a drop of glue on the side of the
valve stem.
As this process nears completion, it is important to work quickly before the glue dries.
1. If it is not already there, place the wheel back in the truing stand.
2. Put on the protective gloves.
3. With the acid brush, apply a third layer of glue to the rim. Let the rim stand for a few
minutes. Do not apply any more glue to the tire.
5. Deflate the tire and place the valve stem into the rim's valve core.
6. WIth your hands at the right and left of the valve, grasp the tread and sidewall of the tire
and press down as you work the tire onto the rim bead (Figure 24 and 25).
7. Continue working down the tire, pressing it into rim until there are only a few inches of the
tire remaining outside the rim bead (Figure 26).
8. Pick up the wheel and slide the tire on the remaining few inches by pushing with your
thumbs (Figure 27).
