If you have the original washer for the derailleur with the stop for the grub screw, you can use a generic band on adapter with a curved plate, like the m:part, just not ones with a flat back
Cheers for that. I guess I'm not going to get anything to them now quicker than they'll get the SRAM one. They said they were ordering it on Thursday but apparently it still wasn't there today.
Why is it that SRAM derailleurs need a SRAM-specific braze-on adaptor for frames without a front mech hanger?
Or are the bike shop lying to me and making me wait for nothing?
Is there anywhere I could get one in London today? Tried everywhere I can think of but I've come up short.
