Tubeless mountain bike tires are a God-send, but they’re not completely fool-proof. And believe me, there are a lot of fools (myself included) who ride mountain bikes!

I suspect a lot of riders, like me, carry a spare tube just in case a tubeless tire can’t be repaired or re-seated on the trail. Then again, maybe not. Fill in the survey below and tell us how you roll.

If you carry a spare tube, what kind?

If you answered “no” to the first question, do you just risk it, or do you have a reliable tubeless repair method to share? And if you answered “yes” to carrying a tube on some rides, tell us how you decide which ones in the comments below.

The adhesive is a yellowish color, contrasting with the tire's black surface. The background shows a blurred workspace with bits of material scattered on a light-colored surface.
