基底戒指 黑色

The black coating isn't just visual—it holds up without chipping, and the fit is precise enough that there’s zero wobble once it’s locked into the traction frame. Setup took me under a minute, and it’s clearly a genuine replacement part.

The ring fits snugly against the base plate and stays put through the whole session, which is exactly what I needed after losing my old one. It's a genuine replacement part so there's no guesswork with compatibility, and the black finish looks clean.
