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. Chromoly construction provides durability essential for competitive racing and intensive training.

Chase Compatibility Reminder Compatible with all Chase Element (2020–2023) and Chase Edge (2022–2023) frame sizes, including micro and Expert XL—all require a Pro-size cassette body. Verify your hub specification before purchase to ensure P3x1 R24 compatibility.
