They can burp as well. I carry a CO2 and a tube. I flatted out of one race as I was so cold I could not get my fingers to work. At one race, I could not get the tire off and ended up riding out on a flat. This year, I am going to carry a foam/sealant CO2 can to get me back out of the course. Also investigating the tire plugs.
Wondering if you are going to carry anything or just continue the risk.
