9.2 - CHECKING WHEEL DISH
• To check wheel dish, use the Campagnolo
wheel and screw or unscrew the measuring screw until it touches the nut or the counter-cup of the hub.
• Place the template on the other side of the wheel and check that the measuring screw (A) rests on the
nut or counter-cup of the hub. If there is any distance between the screw and hub, the wheel dish must
be corrected.
• The maximum permitted wheel dish tolerance is 1 mm.
• Front wheels: if the rim axis is excessively displaced to one side, slacken all the spoke nuts on the same
side by approximately one-quarter turn and then tighten all the spoke nuts on the opposite side by
approximately one-quarter turn; check dishing again and repeat the operation as required, taking care
not to tension the spokes excessively.
• Rear wheels: if the rim axis is excessively displaced to one side, slacken all the spoke nuts on the same
side by approximately one-half turn and simultaneously tighten all the spoke nuts on the opposite side by
approximately one-quarter turn. Remember that the different angle of the right and left spokes (respectively
shallower and steeper) significantly affects wheel dishing; inasmuch, never increase the left spoke nuts
by more than approximately one-quarter turn to avoid difficulties in setting dishing. Repeat the operation
as required, taking care not to tension the spokes excessively.
CAUTION!
The values given above (approximately 1/2 turn and approximately 1/4 turn) are indicative. However,
bear in mind that if the tension of the right-hand spokes is changed in one direction, then the ten-
sion of the left-hand spokes must be changed almost twice as much in the opposite direction.
