Equipment

Equipment List:

Bicycle:

Try to equip your bike with new tires before you leave. Have your local bike shop tune your bike.
Bring 1 spare tire with you - preferably folding.
Bring 3 to 4 inner tubes.
Wheels the same size may have different spoke length since the length is a function of wheel size, hub size and number of crosses. Visit your bike store and get about 5 spokes - note front and back tires may have different sizes.
Rear cassette removal tool if you have one.
Optional but recommended - a bike computer with a GPS feature. Besides tracking your ride after you are done, it will more accurate as to the distance covered.
Optional but recommended - a third water bottle. More for Arizona and New Mexico where it may be hot and very dry.
A bike bag or pannier large enough to carry 2 inner tubes and associated tools.
Lights for bike and helmet
Cycling gloves

Ziplocks for wallet and phone

Clothing:

2-3 cycling jerseys
2-3 cycling shorts
3-4 cycling socks
Helmet

A swim suit
Cold weather clothing and warm weather clothing (or count on layering)
Nicer set of clothes for town when we hit a nicer restaurant.
Consider bringing a small bag that can be used to transport clothing to a hotel (rather than your entire clothing bag). Preferably one that can fold up very small. If you can transport clothing in a bike bag or pannier, so much the better.
