YBN Single Speed Master Link QRS-410 on Sale

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.
