I would only have the CO2 to get home or to another pump, as an emergency. I would be really distracted by having a mini pump in my jersery. I just want to have the feeling that I know I will get home without too much hassle if I get a flat. So a pump attached to my frame would give that feeling. If it means having to fill my tyre every 5 minutes, at least bed will be good when I get home lol I guess petrol stations have pumps there too if I didn't have a pump on my bike or in my jersey.

Although, it sounds like I need both? lol I don't know. It is all very tricky. I do have a standing up pump in the shed out the back. But it is so big there would be no way I can take that anywhere on a bike. I'm doing a charity ride in a few weeks and my dad is driving along in the area as my back up crew. Perhaps I could have that in the car in case something happens? It is quite a good pump, and not too difficult to get to over 100psi.

I'm really confused as what to do now. I understand the two sides of what you are saying. I just don't know which direction to go in now lol I think I've made this all too difficult now
