What's the best way to carry stuff on a bicycle in a 100 mile ride?

[Lizard King]

I have considered using my rack and rack bag, but it seems a little heavy. In the past I carried a fanny pack. Now I'm considering a handle bar bag. I like to have a wind shirt to wear in the cool morning, and carry it later. I also carry snacks, a few tools, spare tube and a first aid kit. I notice most riders in the century just carry a seat tool bag, but that isn't quite big enough for me. Any other ideas?

Most century rides are fully supported so I carry a bottle, tube and tire levers, as for a pump I use OPs. You can tuck a wind jacket into you jersey.

If you carry more, larger saddle packs are made like this: http://www.nashbar.com/profile.cfm?category=600066&subcategory=60001006&brand=&sku=6800&storetype=&estoreid=&pagename=Shop%20by%20Subcat%3A%20Wedges%20%26%20Frame%20Bags

That would carry everything you mentioned with ease. It's cheap and easy to install and remove.

EDIT: don't use a backpack for a 100 miler - really. I recommend a pump over CO2. Too many newbies have carried CO2 and I had to stop and help 'em out. Don't be afraid to ask for help on rides; real cyclists love to help fellow riders and enjoy meeting others in need.

All you have to carry is water.
