@robkerr After contacting stan's, I've learned that an alpha specific rim strip is needed to prevent burping.
3 years ago on Going Tubeless for Cyclocross – Avoiding the Burp, Choosing the Best Tires, and a DIY System (Updated, Part III)
@robkerr thanks for bearing with my pessimism. It's hard, dropping a few days pay on a setup billed as the end of my flatting days, buffering it with a tubeless specific rim, picking a tire off the "worked well for us" list, adding an extra layer of tape, running more psi than I would have liked, Doing well in a race, then my tire belches air. The growing confidence I had in this system went just as flat.
No doubt, till the burp, tubeless is faster, more comfortable, and probably more reliable than tubes, but is the ride/reliablity any better than tubular? If not, why go through all the trouble? As far as I can tell (from what I've read) the only downside to tubulars is the glue.
tubeless for cross seems sketchy and unreliable to me now. I'm sure gluing the tires on works beautifully, but isn't going to that extent for a reliable setup negating all the benefits of clinchers? If we are breaking out the tire cement, and somewhat permanently attaching tires to rims why not get the ride quality and weight advantage of tubular tires in return?
it's the alpha, and my third race tubeless. I was riding at 45 to avoid burping. This is my first season of cross. I've had two dnf's because of flatting. I am so frusterated right now. my next race will be with the alpha/xm and a tube filled with stan's sealant. I figure that even if I pinch, the tire should have a strong enough seal to keep air in. If glue is the only answer, expect to see my clincher wheelset on craigslist soon :(
am I missing something? with two layers of tape, neither the mud2 or vittoria xm fit tight on my stan's rim rim. my xm burped after a remount last sunday resulting in a dnf. I weigh 170 and was riding at 45psi. the mud2 doesn't seem like it will work any better. Also, what it the advantage to gluing tubless tires to your rims vs. just riding tubulars? tire cost?
