**UPDATE** Thanks to good comms with conti, turns out I was sent the clincher not the TL... so accepting I look a clown, disregard the following! On the flip side, the clinchers are pretty good at holding air without a tube...

Just a quick note, I have just been through a Conti GP 5000 tubeless... interestingly used because the Zipp Tangente tubeless suffered an immense slash across the main carcass on day two. All installed properly, 60ml sealant etc. Lost pressure over the first ride, today, which was "luckily" wet as upon returning home I could see multiple air bubbles pushing through the sidewall, otherwise I would have assumed it was a leaky valve etc and wasted hours trying to find the problem. See link (hopefully). For mine to be faulty suggests there are others, so bottom line, there may be a duff batch out. Worth checking before you invest your life tweaking valves etc.

FWIW, it seemed like a good tyre; definitely more robust on the main tread than the Zipp or Pro ones, but the sidewalls did feel flimsy. I love the 4S in clinchers, so I am hoping this is a one-off. Back to the Pro-ones. I've emailed conti.

you may get a quicker resolution from the company you purchased them from.

I don't yet use tubeless on my road bike, but have had self-sealing bubbling like that with some Specialized 2Bliss cross/gravel tyres which sorted had sorted itself out by the following day. A bit disconcerting at the time, but no problems since.

How have you found the 5000's after a bit longer using them?

I need a new set of tyres. Looking at either a pair of 5000's for 80 (probikekit) or another pair of 4000's for 55 (wiggle). Are they worth the extra 25 would you say?
