Cannondale CAAD 8 Ultralight Touring Bike.

That's the biggest problem you have with choosing an aluminium race worthy frame for touring, it just isn't going to be that comfortable. You're going to have to make changes/compromises or whatever you want to call them, as christianSpaceman points out, to make it comfortable.

Like I said earlier, Cannondale are renowned for producing the best and possibly most comfortable alu frame out there, also I have found with bikepacking, it made the bike feel slightly softer in respond (but still a lots more responsive than a lightweight panniers/rack combine), so it work out well in the end, according to my theory that I've yet to test out...

I'm looking at doing something like this at the moment, although I want to go ultralight in the backpacking sense, I want to be fully self sufficient. How much are you planning to carry and which bike packing bags do you have, recommend or will try for this project?

I am planned to be fully self sufficient with tent, sleeping bag, inflatable mattress etc. with the only exception that I don't want to carry cooking equipment which even the lightest one add a whooping 2kg worth of extra weight.

I have a Revelate Designs Viscacha saddlebag that's quite possibly the best saddlebag money can buy, and his latest design is even better addressing some of the fault I've found with the old design.

Framebag will be the Alpkit Stingray which is an amazing value for a custom bag that fit neatly in your frame triangle, I will not be having bottles as a single hydration pack is enough to carry 3 or 4 bottle worth of water which I'll insert in the framebag.

The framebag will have more compartment and room than the current one I got that's also from Revelate Designs, meaning I can carry my inflatable mattress, clothes and toliettes in it instead of the saddlebag.
