Better with 3 tyre levers, and the long ones not short stubby ones. On a 250 you will get by with the short ones, but no way on my 990!

those CO2 cylinder bombs are OK as a back up not the primary means if inflation. The other alternative is slime for tubes. But that is temporary to get somewhere then you must chuck away the tube. It is a way of avoiding tyre removal and bead breaking in a place you dont want to stop long, I carry that as back up. But you still need a way to inflate the tyre.

Carry the best small compressor you can afford. Otherwise once it gets hot it packs up. Mine goes to over 3 bar easy. Had it for years and works well and I use it all the time to top up my tyres. Just look for that Made in China label, and if you see it, be weary!! It wont have a chinaman's chance of lasting a trip lol. Its always more expensive to buy cheap and it is expensive to be poor.

Unfortunately if you look at all the stuff you need, tubes, small compressor, bottle of slime, a groundsheet, a pint of synthetic oil (for me as it is only available in big centres), tyre levers, dishwashing liquid, duct tape, palm size battery charger, chain lube and brush etc. It is half a pannier gone.

Speaking of punctures, I put a new T63 on on Friday. Sunday morning it was down to 0.8 bar. I thought perhaps he didn't tighten valve properly as nut on valve stem was so loose as I could turn it by hand. This morning back down at 1.3 bar.. grrr. They either stuffed the valve or nicked the tube..
