YBN 12 Speed Master Link QRS-12
Small in size but huge in importance, the QRS-12 offers rock solid dependability in a design that can be reused five times. In fact, the QRS-12 is the only 12 speed master link that is reusable at all, let alone five times. With a pin power exceeding 350kgf and four safety sections to prevent false release, it's no wonder YBN has a patent on the design. Add in chromium carbide hardening for extraordinary longevity (as long as the chain's life) and this little link successfully punches far above its weight class.
Compatible with Shimano, SRAM and Campagnolo chains; replace link after five uses or when chain is replaced, whichever occurs first.
Six complete master links with each card.
