CineMilled Delrin Shim for Ronin-M/MX, MoVI, or PRO Ring (2")The CineMilled Delrin Shim, 2" in width, allows you to mount 30mm accessories onto the 25mm handlebar tubes of the Ronin M or Ronin MX, the various MoVI stabilizers, and the CineMilled PRO Ring stabilizer. It has a flange design that lets you simply push the shim onto the place you want it, and it's precision machined from Delrin so it does not scratch or gauge carbon fiber tubes once tightened.
