Might be easier and cheaper than finding shimano someone quote me a set. Preferably black
I already sold the r2c & front, but have a rear to get you started.

Here’s what I have, for $240 gets you a chain (new) and front, rear dear. The Derailleurs have less than 40 hours on them.
I have a brand new set of Zipp Vuka R2C shifters for a SRAM drivetrain. I ended up with a shimano drive so they’ve never been used. I have them on ebay for $275. If you are interested, PM me an offer…they are just sitting here looking for a home.
