I confirm they are tubeless tyres with a tube in ,chortle(Lol). I got mine back on Friday, the valve was ripped away for 3/4 of the circufme.....circumre....base so he couldn't test for holes but I glued and taped it back together so I could put some air in. Theres a minute hole just off centre so I guess that's why I got a few miles out of it once it was deflating. Unfortuneately he didn't find anything in the tyre so i'll just have to keep checking it .
...yes, salesmen. It's ok if they are actual bikists but some are just in sales, be it fridges, ties etc. The trouble is , a lot of the pubic think the salesmen have proper product knowledge.
