This chain has got the chi-chi flair in its favor -- narrow, 9-speed chain, nickel-plated finish with chrome hardened pins. The hollow pin design is for gram shaving. It comes with a gold-colored PowerLink connector to make assembly and disassembly easy, a big plus for people who need to devote regular attention to their chains. It will work with all other 8 and 9 speed cassettes. 279g.
