There is another aspect to interlacing. Some argue that interlacing weakens the spoke at the crossover point leading to spoke failure. One reason, however, to interlace it that if you do brake a spoke and it is interlaced, the crossover will inhibit the spoke from flapping wildly and damaging paint or chrome on forks or stays. When a non-interlaced spoke brakes it will tend to cause such damage. Edward Albert Chappaqua, New York, U.S.A.
