I don't think so, but I'm not sure. I bought the bike used off eBay last year. I changed out one flat but I don't remember which one. Didn't look like one of my patching jobs.

But wouldn't tubeless be kind of a waste on a DH bike? Road bikes sure. Less weight exactly where you want less weight. But in a gravity sport, would seem to me, weight isn't the kind of issue worth a lot of hassle overhead.

Judging by customers' bikes at the LBS, nearly everyone runs tubes. On my mountain bikes, I mainly get flats from pinch-flatting on rocks, so I do have some tubeless tires to try for this year's races.

The first tubeless-ready tires I tried were oppositional-defiant and kept re-developing sidewall leaks after I thought I'd got them sealed (Continental X-King RaceSport), so I picked up a set of the pricey Schwalbe Rocket Ron 2.25" to try next. Schwalbe seems to have the tubeless thing down pretty well.

Tubeless but only because the wheels and most tires I use are really easy to set up. If you have a lot of thorns in your area it's realyl worth the effort but otherwise it's only nice, not necessary. Some converted tires actually feel worse without tubes IMO because the sidewalls flex and fold over too easily in turns.

Really?
Yeah,some of us still use em

Tubes here, going tubeless seems like a hassle.

I don't even see the point with the bazillions of goat heads in idaho, some of them are big enough I've gotten flats on my dirt bike from them. I'll stick with tubes easier to patch

I have both, the stan's does a great job of sealing any holes or punctures on my tubeless setups. A lot less flats on my tubeless setups for sure, at some point I will most likely switch all over to tubeless on all my bikes as time goes on.

Google "Mr. Tuffy" and "spinskins" and "tire liner" almost every bike shop will have them. Or search these forums.

Tubes in front on all three bikes, tubeless in the rear. Why? Because overwhelmingly, my flats have always been rear pinch flats.

Now I'm running lighter and skinnier tires with less pressure. I still have great traction for where I am, and haven't had any flat issues. Think I had two flat/major leak issues initially, due to my setup. Once I got it figured out, have had no trouble.

Roll what works for you.

Rhetorical question.

Tubeless for me. Neither my rims nor tires are tubeless specific. I used gorilla tape to cover the spoke holes, and WSS(go ahead, ask) for the sealant(80 oz for 30 bucks). Tubeless feels better to me because it enables me to run lower pressures that would result in pinch flats with tubes. I run about 20 psi rear, 18 front. Makes rough little high frquency bumps disappear. Cheers

I'm close. I use tubes, and have had two flats in about 12 years. But then again, I run enough pressure to avoid pinch flats, and I don't ride near goat-heads or cacti. (I'm in Oregon!)

Oh yeah, I only ride two days a week in the prime riding months. I ride my roadie in the winter/early spring.

Tubeless for 6 years now. Come to think of it, I haven't had a flat since I made the switch, must be a coincidence.
Reg wheel set, Stan's conversion w/ UST tires. I wore out a set of tube tires, before I switched to the UST's

I know you said it was rhetorical but I was curious, so here's the range:

Panaracer Flat-Away : 25 grams per wheel
Widest regular (non-ultra-light) Mr. Tuffy : 130 grams per wheel.
