good advice?

can be noodly causing efficiency issues, so if your bike is noodly, I'd recommend a change. A noodly bike can occur regardless of the wheel size

Noodly ?

and it was?

i was thinking more road touring that off road stuff were the 599 would be a much better choice.

the op will be touring on road i would imagine, so going by that personally give me 700c every time i just find them a better wheel for rolling and climbing.

Well, flexy. Like a noodle!

I've currently got a bike that is noodly, though I still use it as I figure a reduction in pedaling efficiency isn't bad for me to try to lose some weight. The worst case I ever came across was an old 1980's bike (Ross brand, probably only known in the States) that one of my friends had. It was that bad you wondered if the frame had broken or a joint had failed. Nope, it was just really flexy -like a wet noodle I'm not sure why some frames are so flexy, but it's certainly something you wouldn't want on a touring bike.

Noodly ?

If you have a lot of spare money, by all means buy a etrto 622 bike. However, do not believe the difference will be great. There was a recent test in Bicyle Quarterly, and the difference was statistically insignificant. If like most people you only have one serious bike, use the etrto 559 bike you already have, but with fast tyres. Schwalbe Big Apple 50 mm are comfy and fast. Panaracer Pasela 26x1.75 faster still (but less robust). My own drop bar tourer has etrto 559 wheels. I then choose my tyres depending on the conditions.

What Willem said. "Big wheels are better rolling" is just myth, the difference between 26" and 700c wheels is too small to matter. If you are riding on paved roads make sure to mount slick (not knobby) tyres and you'll be fine.

There was a post on the CTC forums from a couple of guys who'd done JOGLE on Bromptons... there's also a man on there who did it on a (slightly modified) Raleigh Chopper...
