The Shimano CS-R9200 A cassette spacer is a small original equipment part that sets correct spacing between specific cogs on 12-speed Shimano road cassettes. Positioned at a specific point in the cog stack, it maintains the exact gap Shimano specifies for accurate index shifting across the cassette.
Machined to Shimano's factory thickness and structural tolerances, the spacer matches the original part removed during cassette service or rebuilds. Because it shares dimensions across the current generation of 12-speed road groupsets, one part number covers replacement needs across multiple cassette tiers.
