Titanium Tandem - Advice

[tandemrider]

I've been working with Ti-Bikes on a tandem bike. Would like opinions on the frame and if I'm overlooking anything.

I don't know that much about tandem design, but this builder does Z-style couplers, which might be a nice upgrade vs. S&S.

oh, I didn't realize they offered that style of couplers. I'll have to ask them.

Did you consider the UDH standard (Universal Derailleur Hanger) ?
From my understanding of the drawing it doesn't look like to be.
And it is a good option to find easy replacement or eventually going with the new SRAM derailleurs.

They do offer them, but the z couplers don't come in a large enough size for the tubing used.

I did ask and they were able to switch it to UDH. Thanks for the suggestion.
