HARMONIC MINI HUBS
We designed the super-lightweight Harmonic hubs to meet the needs of the raddest little riders. Starting with cold-
forged 6061-T6 hub shells, we added oversize aluminum front axle and rear axle bolts, a Shimano-compatible, 7075-
T6 aluminum casette body and smooth-rolling sealed bearings. A proven reliable 3-pawl cassette body ensures solid
engagement every time. Each set also includes a color-matched, aluminum, BOX, Edge Lock Ring and a gold, BOX,
Zero Cassette Spacer Kit. Not recommended for riders weighing more than 120 pounds. Covered by Limited Lifetime
Warranty Against Breakage.
