text: Previous FrictionFacts testing shows that narrow-wide teeth create no more friction when cross-chaining than do standard, uniform-thickness (i.e., 2X or 3X) chainring teeth, since every tooth on a narrow/wide-tooth chainring pulls the chain over the same amount; it moves narrow and wide chain links laterally the same distance.
