The Rollo Disc enables smoother and more stable crank rolls by providing a wide, predictable surface to stand on. The design is beautifully simple: just slip the axle bolt through the disk and tighten onto the crank.
These Rollo Discs are compatible with KH Spirit crank arms. Moment cranks require a different version of Rollo Disc.
