6. HIDDEN WEIGHTS PROGRAMME
This programme divides the external weight W in two weights W1 and W2 (smaller than the initial external
weight W) located in any two positions selected by the operator.
The two weights W1 and W2 must form a maximum angle of 120° including the external weight W, as
shown in Figure F6.1.
VALID
The angle between weights
W1 and W2 is < 120° and
includes the initial external
weight W.
NOT VALID!
The angle between the
weights W1 and W2 is ≥ 120°
NOT VALID!
External imbalance W not

Fig. F6.1 - Hidden Weights Programme: valid and invalid conditions for use
The Hidden Weights programme is used for aluminium rims when:
• you want to hide the external weight behind two spokes for aesthetic reasons;
• the position of the external weight coincides with a spoke therefore a single weight cannot be applied.
