Midas Gold 12/14T Oversized pulleys for Shimano road derailleurs
King Midas turned everything he touched into gold, which was a great idea until he realized he turned -everything- into gold. For now, we will just stick with our pulleys to match your gold bottom bracket. These pulleys fit on your stock cage, no need to rebuild the derailleur.
These pulleys fit the latest generation of Shimano derailleurs: Dura Ace R9100, Ultegra R8000 and 105 R7000. They also work well with the long cage of a Sram Wifli setup.
By using the standard cage on your Sram or Shimano derailleur and the narrow wide tooth profile, you will get the benefits of reduced articulation in the chain, while retaining accurate shifting. Something that has been a negative side effect of running large pulley systems.
Switching to an oversized set might require to install a longer chain. Here is a video explaining how to get it just right.
