<p>I've been using Iron Cross w/ Specialized Terra Pro 2Bliss and have been very happy so far (2 years) with no burps and holding air.</p>
<p></p>
<p>I've been inching down the PSI to see how low I can go. I weigh 160 and ran 31 last week and rode a small set of stairs each lap, felt both rims hitting each time but had no issues. Today was a grass crit and ran 29 but probably could have gone lower but was nervous to drop more than a couple PSI from previous races.</p>
<p></p>
<p>Your question…</p>

<p>Your question on the max 45 PSI for the rims is with our without a tube. I use my cross bike as my road bike and originally bought two sets of Iron Cross - one to set up with tubes/road tires and one tubeless for cross.</p>
<p></p>
<p>My LBS knew my intentions but didn't think it was going to be an issue but after reading some posts and contacting Stan's directly they confirmed the max was for any set up.</p>

They could have finally sealed properly. I would run low to mid 30s if you are still worried about air leaking. It shouldn't lose to much air during the 30-45 min of racing. 42 sounds like it will be rough and you will have less grip making the corners feel squirmy.

<p>So here's my follow up question: </p>
<p>- Tires have 26 and 34 PSI in them today (haven't touched them since Sunday). So I'm guessing that they're holding air. </p>
<p>- If they're holding air, I thinking I must have burped them OR just became uncomfortable during the race and I felt they needed more air. I didn't hear any air leaking (which I've certainly heard in the past).</p>
<p></p>

<p>Latex tubes arrived...now I'm torn over whether to ride them hard (40/42 PSI) or put in tubes, which I'd ride hard anyway. I suppose at this point I'll be running them so hard that the only benefit would be no pinch flats.

<p>Have had good success with the S-works 2blissCX tires and the new Schwalbe tubeless CX tires.</p>
<p>Take a look at the Specialized ones. They'll even hold air quite awhile w/o sealant and the tires are readily available.</p>

<p>Are you running tubeless specific Vittoria's? </p>
<p></p>
<p>I've gone ahead and ordered latex tubes. Pitting every race isn't a lot of fun and I can't imagine I'm saving that much time in the corners. </p>

<p>thanks for your insight! </p>

I weigh 160 and run mid to high 20s for psi. I am using Industry Nine Ultralight CX wheels. I have run tubeless in mtn bikes for years and in cross and gravel the last 2 years. I have run the mxp and mso and I would lose a couple psi over 4-5 days. It took me 3-4 days of setting them up to hold air for that long. It seemed to take 4 oz sealant per tire and constantly shaking and flipping them for the 3-4 days. I switched over to Vittoria and Specialized tubeless tires and they held air without…

It seemed to take 4 oz sealant per tire and constantly shaking and flipping them for the 3-4 days. I switched over to Vittoria and Specialized tubeless tires and they held air without sealant up to an hour and takes a couple weeks to lose a few psi after sealant. Tubeless specific makes life easier. I did burp the mxp before and never with the tubeless tires. Hope this helps.

<p>There's a lot of guys on this forum who have more experience than me, but overall, I'd say you should be able to expect that your tubeless tires shouldn't be leaking much air, if any. I'm running some WTB Cross Boss tubeless on HED Ardennes rims this year. No issues. None. Nada. I'd add sealant, swirl it around, then dip the inflated tire into a tub of water to check for leaks. If you can't solve the issue, head on down to your LBS, and good luck...<br/>Ken</p>
