I used to use ProCrunch in Auckland & it was soooo yummy & kept me rollin..Now the only way to get them is order them online from qld.
REI ( www.rei.com )carries Luna Bars (among other yummy energy bar treats) and ships world wide as far as I can tell. I don't know if they have restrictions about shipping food items, but it might be worth a try. None of the energy bar/drink companies are in the list of brands that can only be shipped to the US and/or Canada so I suspect that you probably can get them.
the international shipping rates are fairly high so you'd have to order a lot to make it worth it - maybe you could get together a bunch of people who want to try them?
I buy muesli style bars for kids lunchboxes... the best I have found to eat WHILE riding (that is, not pulling over to side of road to eat which I don't do) are the "Mother Earth" brand - Baked Fruit Sticks (apple) or Fruit Bars (apricot). They are soft and not chewy and moist enough not to get stuck in the throat as you chew and swallow while riding.
However, that being said my longest rides sit just under two hours... I'm not an enduro rider.
Roadraven..I use leppin on my long rides & swear by it. Had i not done the round taupo in 04 I wouldn't have discovered it.
I don't normally stop to eat while riding & try to keep on truckin. Eating a banana while riding can be fun..
Yum. Mother Earth stuff is good. I just tend to take fruit and/or a muesli bar(s) and water, but I don't tend to do more than a 2hr ride either.
