The weak point of these hubs was the sun gears, and the system of fixing them to the axle. The original system used a sliding key, similar to that used in the Sachs/SRAM hubs, but one-sided (projecting from one side of the axle instead of both). This key and the notches that it engaged were prone to having their corners rounded off and then not yielding proper engagement. The next system used small ball bearings that would retract or protrude from the axle and engage the sun gears. Unfortunately, under extreme torque the sun gears tended to override the balls, either becoming permanently engaged with the axle or shattering. Back to the drawing board, eh? | The weak point of these hubs was the sun gears, and the system of fixing them to the axle.
