Are Hope pro4 and rs4 freehubs interchangeable?

Posted on
  • I’m getting confused by hub “standards” - please help!

    I want to run a sram XPLR 12 speed cassette on my hope pro4 wheels (which currently have a standard Shimano hg freehub).

    The cassette I have is XDR compatible only. Not XD.

    I’m have previously used the Hope hub537 freehub to run XD cassettes on my other set of pro4 wheels. But I want to know how to run XDR.

    • can I run a 12 speed xdr cassette on hub537 xd freehub? (I assume not. Xd is shorter than xdr, right?)
    • therefore- can I run the rs4 hub544 on my pro4 hub shell? The hub544 is xdr - but it’s designed for the rs4. Are rs4 and pro4 freehubs interchangeable?

    Thanks for help!

  • Shimano wise yes i have done the swap but never had xd

  • Fyi. I got confirmation from hope that answers my question and confirms they ARE interchangeable. So if you need to run XDR on a pro4, you need the rs4 driver.
