Simply put, you want to carry a track tubular as a spare. Don't take it from me though, I actually learned this trick from former Ironman World Champion Peter Reid. The reason for this is because they roll up to nothing, weigh nothing, and despite what people believe, they are actually fairly robust. Track tubulars usually don't have the puncture protection strip that most road tubulars have, but don't let that scare you off.
|Tufo Elite Jet (Top) - Butyl Tube (Bottom)|
My personal experience with this tire is that it is a fairly robust tire. At Ironman Wisconsin in 2009 I actually had to change a flat and ride this tire for 55 miles and it handled like a champ.
I have done a lot of general tire testing and I find that when you have a flat that the affecting object will go through any tire. Rarely is it the case the the object would go through one tire but not another.
If you are still worried about flatting then you can always carry two Tufo Elite Jet 120s and still be under the weight of one Zipp Tangente. In addition, you can also move up a step to the Tufo Elite Jet Hi-Tpi <160 which includes a puncture protection strip in the tire.

For those real weight-weenies out there, Tufo makes a 110 gram version with a width of 19mm, but I prefer to ride at least 21mm tires for the added traction, and more comfortable ride.
