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.

Hi Tandemrider, is your ti tandem build complete? I'd be very happy to see pics and hear if you'd go for the same geo again. I've a aluminium/carbon race tandem from Tank Bicycles and as it doesn't have more than 25mm tire clearance, I'm interested in ti tandem frames.
