Small in size but huge in importance, the QRS-410 offers rock solid dependability in a design that can be reused two times. In fact, the QRS-410 is the only single-speed master link that is reusable at all. 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 two uses or when chain is replaced, whichever occurs first; for simple installation and removal use YBN's master link tools found in our Tools & Equipment section.
