Campagnolo Sprocket 11 Speed 13A 11S-131

This sprocket from Campagnolo is designed as a 13-tooth A-series replacement cog for compatible Campagnolo 11-speed cassette setups. It is useful when a single cassette sprocket is worn, damaged, or causing chain skip, rough shifting, or poor chain engagement under load. Replacing only the worn sprocket can help restore smoother gear changes while keeping the rest of a compatible cassette in use, but the exact cassette model and 11-speed fitment should always be checked before installation.
