So bought a coupled tandem with 700c wheels and have a trip planned for May. We used to travel with a bikefriday and it was pretty easy. With the 700c wheels I have to take the tires off the wheels to get them into the cases. I know with all the assembly and disassembly taking tires off isn't much more but I also figure having a second set of wheels might be nice. I've read 26" wheels are more durable and will fit in the cases without having to take the tires off.

I know this may sound like a silly question but wondering if the width of the wheels are appropriate will I encounter any challenges if I buy 26" wheels and put them on the bike. I should also state the bike has dual discs. I can't really figure out what problems I would encounter but figured I'd ask before spending a couple hundred on wheels, rotors and cassette. I've read I may want to consider changing the cassette configuration as well.

My wife thinks I'm being ridiculous and having to take off the tires isn't a reason to get another wheelset. She's usually right.
