It's been many a moon since I've switched to 700c. Overall I'm happy with my current stable, but it's not very convenient for traveling with a bike, notably flights.
So, I'm looking at a 20" folder again, for touring purposes, and also for relaxed rides when speed is not particularly important. Mostly light touring on pavement with panniers; if I ever need to haul lots of stuff I'd probably use a trailer. Low gears, drop bars, standard parts (preferably 105-level quality), can fit into a big Samsonite Oyster.
Before I order a Bike Friday is there anything else / anything new I should be looking at?
