Taking a spare not a bad idea (I had to buy a new tyre on both tcr and indypac) but I would take something different, easier to get on and not tubeless.
I’d not run tubeless. Probably run the 32s. I’ve been looking at tubilito inner tubes. Really rather costly but stronger and lighter is very tempting. Just not come across anyone using them.
I’m pretty set on running GP5000’s.
Also light enough to seriously consider carrying a spare but that doesn’t seem the done thing.
