• If you don't own the SLX rear mech already just buy the GRX one, if you need to get it to work with bigger cassettes you can always add a Roadlink, much neater than a TanPan solution

  • Don't have anything at the minute, just saw that the SLX was £50 new as opposed to the 11 speed GRX being a lot more and I vaguely remembered hearing that GRX was compatible with MTB bits.
