multi tool kit, saddle bag, bottle cages, computer
kickstand :)

for the saddle bag:
tire levers, co2, tube, or if you like the minimalist approach, check out the "Awesome Strap" from Backcountry Research
for safety:
rear light
and for good measure: this

Helmet

+1 I don't see how you can ride without one.

I also like the contrail idea. I want one of those for my next race. That would be a great race bag gift. 400+ chalk lines around the course. It would be cool.

I would go with:
Helmet
Gloves
Light
aerobar
Computer
tube/patch
botles/holders
seat post
pedals
shoes

I think everyone has hit it...but I'd love to add: Baseball cards and clothes pins. Maybe a horn too.
In fact at this years IMLP I'm thinking of a horn or bell instead of having to constantly say..."On your left!"

Anton, Good for you, do you pass that many people on the bike portion?

I like how you slipped aerobars in there. If you get aerobars you'll have to change up your geometry for fit concerns, it's definitely not 'must have' for a while until you get really serious about dropping time in a race. Otherwise all other suggestions look good. Definitely get yourself one of those chalk dispensers, you'd be the coolest kid in school.

I saw they have air horns for bike riders (I don't know where you would keep it) but that would be funny to see the reactions of drivers when you blow it!

I like the bell sound better than a horn...reminds me of that song by Queen "bicycle race"

You can clean it with rags in the garage, or get a set of brushes/sponges...

I can't tell your gender, not that it matters, because a razor is a required necessity regardless. Also, get a [url=http://www.roadid.com]Road ID[/url]. I've been hit and it worked. Both times.

yep, that's the one- did the lyrics come off the top of your head, or did you have to look them up?

I agree with most of the above (maybe not the air horn or kickstand, but to each his/her own).

The only thing I'd add is a CO2 chuck. And practice using it at home before you have to do so for real.

don't forget clothing...

or then again, maybe not

riding nude CANNOT be comfy...for anyone involved

+1 to road ID.

I have a spare tube + CO2 - but I have not yet taken the time to learn how to actually change a flat.

So, I would add KNOWLEDGE and ABILITY to use said flat tire changing gear.

Yes, I am embarrassed.

For longer rides, I really like a Bento Box type of pouch for easy quick access to food/gels. I don't like carrying stuff in my jersey pocket. it itches from the moving around.
A flashing light for visibility if you're riding around at dusk/dawn/dark.
A cell phone and some cash in case of emergencies.
Also, I wear a RoadID bracelet because you never know if something really bad can happen and I don't want to end up as a John Doe.

+1 to Road ID. And Millman, you really need to learn how to change a flat! Takes 5 min. to learn.

it took me about an hour, some tears and a little road rage, but I did it, finally. I should practice to refresh this season tho

Right. takes 5 minutes to "learn." Took me 30 minutes to actually do it myself the first time. I am getting faster tho thanks to some glass in my tire I didn't know about that kept popping my tubes. Ugh! Live and learn...

First, Road ID and cash...

In fact, the cash in my Bento Box is from a tube I have someone during a ride, and he insisted that I take $5 for the tube. So I left the cash there, and bought a new tube.

A Razor Blade, Tufo Tape, and a Tubular! Easy to change, slice across the tire, insert finger into the tire and pull it off the wheel. Apply Tufo Tape to rim, roll new Tubular on, rip plastic off the Tufo Tape, inflate and off you go. Three minutes tops!
