- Notes
- Engagement point count varies in sources between 12 and 24 depending on production year and variant. 24 POE (3-pawl, 24-tooth ratchet) is the most commonly cited figure and is used here, but this is moderately low-confidence. Discontinued; no current MSRP on sram.com. Full service docs remain available at sram.com/en/service/models/hu-x9-a1.
