I think Burley calls my tandem (the Zydeco) a mixte, though I'm not sure I agree. It came with a 3x7 drivetrain, and last year, I upgraded the rear to 11-speed, so I have the only 33-speed bike I've seen. And all those gears are not wasted. It's like driving a tractor-trailer, rowing through the gears on the hills here.
