1.85mm Low Spacer
The Volt uses a standard 11-speed HG freehub which is longer than previous generations. If an 8, 9, or 10-speed cassette is installed without this specific 1.85mm spacer, the cassette stack will not be wide enough for the lockring to exert axial pressure. This results in the cassette oscillating on the splines despite the lockring being torqued to specification.

JetBlack Volt Freehub Body
Internal bearing degradation or race pitting within the freehub body itself can cause lateral movement (wobble) relative to the trainer's main axle. This component houses the pawl system and the primary drive bearings; replacement is required if the play persists after ensuring the axle end-caps are fully seated and tightened.

Axle End Cap Kit
The freehub assembly is held in place by threaded or press-fit end caps that provide the necessary preload for the hub bearings. If these caps vibrate loose during operation or were insufficiently torqued at the factory, the entire freehub and cassette assembly will exhibit lateral play along the axle's longitudinal axis.
