What do you do with these if you get a flat? Im used to inner tube. Is it a case of placing a patch on the inside of the tyre covering the cut/thorn hole?

Regards.

In what sense? Is this whilst on the Trail or at home post ride?

If you're running tubeless you should have sealant in the tyre too. This will seal up 'thorn' holes. If you slice open the tyre, on a rock for example, then you need to put a patch on the inside of the tyre. In which case you need to take the tyre off to do this. If I do this on the Trail I stick a tube in to get me home. Although you can carry 'one-shot' containers off sealant.

I've twice cut tyres badly enough to throw them away but these tyres had loads of sealant repairs visible on the inside when I took them off.

Thanks mk1fan. Post ride, i just got the bike today! It looks like a small cut and i take it you use normal puncture repair patches? As far as i can tell it has no sealant inside. Can u just get a can and spray it in?

A tubeless system is useless without sealant. You can just add it to the inside of the tyre and I *think* you can also top it up through the valve. This will seal any small punctures and reduce air loss.

You will also need a track pump in order to get the tyre to seat on the rim.

I have used a couple of layers of electrical tape but you can get dedicated tyre repair patches. Sealant can be got from most LBS's and there are plenty of different makes. You can also make your own.

I use CO2 cartridges to seat the tyres but they can be seated with a decent track pump. I am looking at cheap 'dry' compressors at the moment. Stan's No Tubes have a fitting that converts Presta valves to Schrader values which makes using a compressor easier.

As Mk1fan says. On the trail just put in a tube (after checking to see if the cause of the puncture is still in the tube!) as a quick fix. You will need to remove the valve first which can be difficult with cold fingers so put a small pair of pliers in your tool kit to release the locking ring.
