2.8WHEEL LACING: 21 INCH RIM
GENERAL
If only rim is to be replaced, tape spokes together to hold pos-
ition on hub and remove spokes from rim. Install taped
hub/spoke assembly to new rim and tighten spokes. Then
remove tape and true wheels.
NOTES
• Do not install incorrect spokes or spoke nipples on rim.
Steel laced rims use zinc plated spokes and spoke nipples.
Chrome aluminum profile laced rims use chrome plated
spokes and spoke nipples. Using incorrect spokes can
result in improper thread engagement which could result
in damage to rim, tubes or tire.
• Steel laced rims use zinc plated spokes. Chrome aluminum
profile laced rims use chrome plated spokes.
See Figure 2-43. Measure distance "A" to determine spoke
length. Refer to Table 2-12 to determine correct spoke length
for type of rim used.
