I have a SRAM Compact Crank, Shimano Ultegra Derailleur and Shimano Ultegra 10spd cassette. Shifting is ok, but chain (shimano 105) is a little old, does it matter which chain I replace it with? Would I be better with a SRAM chain or Shimano or Wipperman for smoother shifting? Or does it not matter…thanks.
