I thought I was done expounding on tubeless road tires last September; mostly I was recounting their various annoying aspects because they are usually overlooked in all the hype around The Next Greatest Bike Thing. I’ve been planning to switch the tubeless tires to regular tubed tires after the Schwalbes wore out. The reason for going back to tubes was that I wanted to be able to switch tires back and forth on those wheels depending on where I was planning to ride next, and tubeless sealant would make that a big messy hassle. (Of course the other option would be to spend a lot of money on another set of wheels; then I would a knobbier pair for fire roads/ pavement and a smooth set for pavement/occasionally fire roads.)
Then yesterday we went for a ride in an area that was replete with street debris. Let’s just say either their street cleaning is infrequent or their residents like to smash bottles. A lot. I ran through a couple of piles of glass but didn’t give it much thought other than to make a note to check the tires later on. With tubeless even that is unnecessary if the tires are still holding air. We made it home and I threw the bike in the corner.
This morning I checked the tires. 95% of the time I don’t find anything. Rather than glass this time I found something else embedded in the rear tire:
I thought it was just a flint since only the head was exposed. When I pulled it out I realized it was an entire nail. The tire had held pressure, which is why I hadn’t notice anything amiss. Of course when I pulled it out, air rushed out. I quickly rolled the wheel so the hole was at the bottom and sealant bubbled out. Within 30 seconds hole was sealed.
So despite tubeless tires having a set of problems all their own, in the usual use case and conditions they work rather flawlessly. I was able to finish the ride ignorant of the puncture and probably would have ridden a lot more with that nail still embedded if I hadn’t decided to be Boy Scout-like and check them the next day.
So despite my trepidations about using road tubeless, there are times when they are truly awesome.
