Continental should label they're tires more clearly (prev. Notubes valves suck!!!

intheways · May 17, 2015

Alright, I take back everything I said about Stan's. Their stuff is solid.

I do think Continental should clearly state that specs on the tire refer to tubed tires.

How would a valve stem failure make the tire blow off the rim?

My thoughts exactly!

And how does a blown valve damage your tire? I guess... Just looking to rant or actually looking for some kind of advice?

I was pretty surprised that it blew off the rim too. I guess the pressure discharge blew it off. The bead is all messed up and the rim (with 1 ride) dented in a spot where the wheel landed after the valve broke.

I tried another valve (Stans) and the tire (conti xking) doesn't seat properly.

I usually don't like to post *****y things, but this cost me a race, tire and damaged the rim.

dledinger · May 17, 2015

This happened when inflating or while riding?

intheways · May 17, 2015

While inflating. It didn't really cost me a race, but I had a race scheduled the next day and my last tube had a hole. That's my bad

Conversely, I like Stans Valves. I don't care for their rims, or hubs, but their valves are shaped to work with most every rim manufacturer, and removeable cores are great.

Never change your setup the day before a race. That's all I got.

Other than I use American Classic stems with no problems.

What PSI did you inflate to?

mca90guitar · May 18, 2015

Mine seem to work fine, idk how the stem would cause a failure. Maybe you over pressurized the tires?

Alias530 · May 18, 2015

My Stans ones work fine... the Specialized ones suck though.

Bontrager are my favorite though. Solid metal, rather than rubber molded around metal that can break (and usually does on the Specialized ones).

intheways · May 18, 2015

No doubt, but it was leaking air and I was just planning to add some sealant

It blew apart at 60 psi. I was trying to get a good seat on the rim. The tire is rated to 65, so I would think it would cause it to blow off.

I couldn't understand at first how you can blame a Stan's valve.
My tires normally seat at around 25 pounds that's using Specialized and Maxxis tires.

It was a velocity blunt ss

the-one1 · May 18, 2015

The problem is user error. Had nothing to do with the stem. 60 psi in a tubeless tire is a no no.

This is too.

Notubes valves suck!!!

And the plot finally unravels...

If you went to 60-psi, the tire was already sealing for a good while. If the bead was not aligned properly along the rim, it was probably because of lack of lubrication (sealant or soap) and not lack of pressure.

Op should change title to "I Suck Hard Notube Valves, Awesome At Rimming Your Uncle".
