INSTALL – RIM TAPE & VALVES
You will require about 10-15min per rim to complete the tape installation. If you have any questions contact us direct.
Bouwmeester rims are different compared to conventional rims, so require a different taping system. For stress free tyre mounting and tubeless sealing follow these steps.
Knife & Scissors Cutting and finishing rim tape
Grease Syringe Teflon based grease, carbon safe. BC use Nulon XL70
Prepsol or Isocol A wax a grease remover
RIM CLEANING & PREP
1. Wipe clean rim inner well using the wax and grease remover. If the rim is old make sure it is well washed and free from all dust and dirt.
2. Dry rim with clean cloth or air gun. Use eye protection if using air gun.
NIPPLE PLUG INSTALLATION
IMPORTANT: Nipple plugs are critical with Bouwmeester rims. They do 3 things;
– Holds the correct shape of rim profile when tape is applied. If you don’t have plugs the tape will fall into the mound cavity and air will escape when inflating the tyre.
– The plug protects the tape from damage from the nipple, especially if a broken spoke occurs
– The nipple plug applies a small amount of pressure on the nipple preventing them loosening
3. Place the wheel in the trueing stand. Using a small grease gun or syringe place a small 2x2mm blob of grease on the back of nipple head, do this for all nipples.
4. Then place the nipple plug and press plug on nipple, it should have enough adhesion from the grease to hold in place for tape installation.
5. Keeping the tape under constant tension use your thumb, press the tape firmly in the well of the rim. TIP: Put a rag over your thumb when pressing the tape in the rims well. This will help form a good shape for even pressure and assist sliding your thumb on the tape. Also a slight side to side motion with the tape will help it slip into the well while under tension.
TIP: It is important that the tape is placed deep in the well (Diagram B). If it is too shallow it will make tyre installation difficult as the bead of the tyre will not sit into the well as designed.
6: Overlap the tape (Diagram A) and cut the tape at 90deg. IMPORTANT: Make sure the tape is securely sealed at the end of tape. If the lip of the tape is not fully adhered this will cause seepage of sealant under tape.
7. With a sharp knife cut a neat round circle in the valve area. It is important not to cut oversize as this can cause sealant seepage under the tape.
8. Press the valve through the hole firmly, it should be a firm seal. Tighten the valve nut firmly while pressing firmly on the rubber part of the stem.
IMPORTANT: Make sure the valve is securely tightened. Both the valve nut and rubber grommet end should be flush (Diagram C).
