I have a new S Works Venge with Roval tubeless front tire only that leaks frequently. I have local good bake shop check leaks three times and hold it over night, after one ride it will completely flat. also I have reinstalled the tire with new sealant twice according to instructions and the most the air has held was one week. I think this is a bad design or bad wheel, anyone have any suggestions?

There are a lot of questions....are you using tape or the included Roval plugs? Are you using a tubeless tire? Are you seating the tire fully? In general tubeless should work, and I would expect some pressure loss over a weeks time....but it shouldn't be completely flat. Like tubes (especially latex) you should be pumping up before each ride, and the pressure should remain pretty constant over the course of a ride. Can you see a spot where the sealant is pooling and clotting? The leak might be there.

You could also check that the valve is seated properly, and that the valve core is snug and functioning well.

Yes I have had the dealer who is a specialized dealer check the rim Valve everything that is possible the issue is the tire is inconsistent and would leak either immediately or be OK for a week.

Check for leaks. Spray it with soapy water and check for a small leak.

It's probably not in the tire but around the bead or rim.

Also is it both wheels or only one wheel? Could the rim be cracked or damaged?

Could it be that there isn't enough sealant in the tire to coat the inside of it completely and take care of leaks? Is the bead of the tire completely seated? Is the rim tape sticking to the rim completely?

So... it is the tire then? Thanks for the update.

Well, if you don't install them yourself, there is no way yo tell what is going on. I have questions about the plugs that Roval uses. I think that there is more 'risk' of leakage than with tape. As part of my long-term tubeless test, I have added a set of Bontrager Aeolus 5s (I didn't have a carbon set in the test) this week. When I got them, the tires were installed already. The rear leaked inexplicably, too. I ended-up redoing them myself and they are perfect now. There is no way to tell exactly what was wrong with the original install.

I would recommend that you strip them and reinstall yourself, only then you can be sure.
