“The Shimano HG40 8-speed chain shifts well with the Shimano Sora HG50 rear cluster. After about 750 km the chain was 50% worn. To extend the life of the rear cluster and the chainring, the chain should be changed when it is 50% to 75% worn.”
“The shimano master joint in this pack is a big hard to attach, resorted to YouTube for instructions, hard to attach without bending the chain, but perfect size for 8 speed commuter”
