A follow up question if you don't mind. Turns out I'll have the option of a 24/21 or a 22/20. The captain's compartment on those two sizes falls on either side of my single size, and I would instinctively go for the larger frame for added comfort on long rides. But I also recognize that I'll be holding up the stoker when stopped, something that will be easier with a smaller frame.
Given that, how much standover should I be looking for?
TIA again.
