These came on complete Clems but we took them off when we figured out that the cable routing/pull actuation isn't friction shifter friendly. They have the Sneakypull affliction. They're a great choice for Brifter/Trigger bikes though.
These are fine if you're using a trigger shifter or brifter. No packaging, no returns. Shims included. If you have a 34.9mm seattube you can get either size.
