• As the title suggests, I just got the Shimano 11-34 cassette and looking to replace an old 11-32 cassette. Will I need to install a new chain, or will the current length chain suffice?

  • Something like half a link difference so no. Test big-big combo unless you just have 1 ring. Just check the cage angle and make sure its not going to kill you with fire and spokes
