Do you guys carry co2 then on race day and a spare inner tube? Are you tubeless or clinchers here?
I’ve never used co2 before, so i guess that’s more flippin stuff i need to buy! 
Even on a budget, this is getting expensive. Ultra running is soooo much cheaper!!
It was a lot easier before I switched to latex. I just used to use Conti Race light 28 tubes, and had those in the necessary range of long and short valve stem lengths. But as you are finding, latex tubes seem to have a lot less variety.
It’s been a bit more faff, but 4-5w across my pair of tyres now seems like a worthwhile upgrade simply for some inner tubes costing a few quid. Plus, the benefit I didn’t know about before switching to latex was the improved “ride”. It was very noticeable after years on butyl
Yes, clincher and use co2. But that’s what I carry all the time anyway. You can by the co2 off ebay for pretty cheap. I used to carry a mini pump, but the first time I saw someone inflate a flat on a group ride in 2s using co2, I was never going back to spending minutes and loads of energy pumping up a tyre again
Yeah same. Tho will now carry a spare Co2 incase I c0ck up a bit.
If I puncture twice I’m sacking it off anyway 
Ok dumb question - do i need some sort of adaptor type thing, or is literally just the cartridge that i need (that fits onto the tube valve)?
I know i could google this, but if you have any recommendations of said parts, that would be grand.
I’ve got a Chuck and a pump with the adapter.
Chuck for racing, pump for daily riding.
If I flat whilst riding once, I’ll use the C02 first.
Second time and it’s the pump 
No, you need some kind of inflator, and then the cartridge.
I have one like this (albeit an older model) that I’ll take out when training: Buy Genuine Innovations Ultraflate CO2 Inflator - INULT20 | Tweeks Cycles
As it has a trigger, etc, it just makes it a bit easier. And the plastic tube stops the problem of the co2 cannister going ice cold as soon as you start to inflate.
For racing, I use this: Buy Genuine Innovations Microflate Nano CO2 Inflator - INMFN20 | Tweeks Cycles
It’s smaller to fit in a spares kit, and also is sleek enough to still work with my narrow disk opening. But you need to remember to get a little foam wrap for the cannister, otherwise your hand is getting stuck to it!
Or just use some duct tape
Nice, never heard of that tactic. You can confirm from experience that it insulates from the cold enough to work? If so, then that’s certainly easier and something you can just prep the cannisters with.
I like the idea of the nut. I just have my co2 in my spares bottle (BTS). I tried using the built in screw bits that are on my BTS mount, but as you say, I lost them every time I tried as they just unscrewed
Yeah I just added this to allow me. I normally carried it in the spares bottle - but wanted 2 after previous mishap.
Only 1 side seems to unscrew which seemed weird. The nut won’t go far down, but seems solid - I’m hoping things would start to rattle by that point if its worked its way loose.
Yes. I changed a tubular on Sunday using a C02 canister which had been wrapped in duct tape
For a long course race, I think I’d have at least 3 in my spares bottle. My race would be over, but with all the money and time investment, I’d want to finish. I even stick another tube and co2 in special needs, just in case I’ve had a nightmare in the first half of the bike.
I have quite a lot in my spares bottle for a long distance race. 3 tubes, 3 co2, inflator, levers, multitool, and even a spare quick link
HOW you cramming them in? Ive got one and patches. Id like to take 2… but didnt think I had room!
Easily enough space for the inflator top left, and the co2 on the right.
Might reconsider for Wales, as weight will factor
So Where’s all this going? Into a spares bottle behind your saddle yeah? Along with another bottle of fluid?
Yep
Piece of old tube works well.
Co2 infalters- make sure you get one that pushes on not screws on. Screw on will almost certainly mean you unscrew the valve core when it freezes to the chuck and try to remove it and then you are royally f*cked.
Whatever you use, don’t let the race be the first time you use it.
If you have used some of a cartridge don’t expect there to still be some air in it next time you come to it - bin it.
