CB-X 純正 Uリング用ロックピン 4個セット ホワイトまたはブラック

The smallest pin clicks in perfectly snug—no more rattling when I move. I've tried different sizes for comfort, and the variety here really lets you dial it in.

The set giving me all four sizes in one pack is honestly the best part—no guessing which pin fits, I just tested each until one locked perfectly. The white finish matches my device cleanly and they slide in smooth without any rough edges. Took me a minute to swap, but once it clicked, it's been rock

The four different pin sizes in one pack make it easy to swap until you find the right fit, though the white finish shows scratches quicker than I'd like. It works as expected with my existing ring setup.
