Advice on my Old Look 595

[hairylegs]

Hey all,

I'm 3 weeks out from IM Cali and my old roadbike which I've converted to a tri-setup with deep wheels and even a disc wheel is giving me fits. The old 10 speed Di2 gave out, so with some help upgraded to a used Ultegra 11 speed group. But now the RD hanger is out of whack and is having trouble accepting the new, beefier RD. Add to that the bonding of the seat stay and chain stay has started to delaminate. The wheel should hold it together, right?

Shall I...

1) attempt to epoxy them back together for a little piece of mind, and shim the RD hanger so I can install the new RD?
2) look for a used frame (rim brake) XL and Di2 capable in the 11th hour?
3) try and borrow a bike?
4) gulp...buy a used bike? most are likely disc so my wheels would not be compatible.

I've got about $1700 into this bike including the wheels, most of which can be repurposed, but not good news!

Thanks for any help. I've trained so hard for this race and was really looking forward to doing it on this bike...
