One way to check would be to see how much adjustment you still have on your B screw. For the 42 I have it in all the way and for the 34 it's at about midpoint of adjustment.

The frame is custom titanium from Hugh Black of True North Cycles. The fit up and sizing was exactly as expected, I don't think we'll have to tweak the positions at all. The finish is very good and everything went together very easily (once I had the right parts). From the time we started thinking about getting a new tandem to having the frame in hand was less than three months so I'm super happy with the speed of the process. We had a pretty good idea of what we wanted and I think we went through 5 design iterations.

The drivetrain is Di2 11 speed with 50-34 up front and 11-34 in the rear on these 700c Woven carbon wheels with Compass 38 mm tires. I have another set of 650B wheels with 48 mm Gravel King SK tires and a 11-42 cassette. Both pairs of wheels are set up tubeless. I bought a Wolf Tooth road link but it looks like the derailleur will handle a 42 just fine so I may not need it. I already love the XT gear display. Brakes are hydraulic.

I had some challenges getting the right length axles for the Middleburn Cranks but now that that's sorted they look good.

Carbon bars front and rear and a carbon Cobble Gobbler seat post on the back for Sue. Aluminum seat post for the captain. Enve cross fork.

The bike weighs in at 29.4 pounds without pedals and 31 pounds all ready to ride with the 700c wheels. Of course once we load up 6 water bottles it really doesn't matter.
