Installation Notes Remove rear wheel and disassemble hub body from axle. Install new cassette body onto hub axle, aligning splines. Select appropriate spacers (0.5mm and/or 1mm) based on cog thickness. Install selected cog onto cassette body threads. Thread lock ring hand-tight until cog seats firmly. Tighten progressively in alternating directions (left-right) to ensure even clamping pressure. Verify cog rotation is smooth and free and engagement occurs immediately without delay.

Maintenance Notes The 3-pawl engagement system provides reliable power transfer across extended racing and training. Periodically inspect pawl teeth for wear; if engagement becomes sluggish or delayed, individual pawl and spring components can be replaced without full cassette body replacement. Sealed bearings require no regular greasing.

Performance Note 24-tooth roller design delivers smooth engagement suitable for riders across all skill levels and disciplines on 24" bikes. Chromoly construction provides durability essential for competitive racing and intensive training.
