LoL... I found a 1986 Cannondale SR500 that looked like it had spent the last 25+ years being shuffeled around in the garage. The components were mint. The frame was a bit scuffed up, but it was a horrible color. So... I pulled all of the fresh Shimano 600SIS components, used them to restore my Raleigh Competition to all original, stripped and powder coated the Cannondale frame, and threw a carbon fork and 600 Ultegra Tricolor components.
Wait a minute... are we allowed to talk about bikes in here?

I have, I have. When posting that I'm sometimes concerned I might hear from some internet activist about political correctness, etc. In actuality, it appears the woman's size is highly correlated with powerful, rich voices cherished in opera and theatre. So it's a good thing if you want to be a good singer. The other day I took notice at how big Kelly Clarkson has gotten recently.

That's what they always say about steel, yet like the Phoenix . . . . . . . . . you know the rest. 
I remember back in 2004 when I was shopping for a new bike at a prominent joint in NYC, and the guy tells me dismissively "nobody rides steel any more". I walked out the door . . . . how could I possibly trust anything further he might say.
Eventually I got a Ti bike that year, but it wasn't going to be from him.

So I havent told y'all yet what happened to Hillclimber last week.
He was descending a local hill, 5% grade, 3 miles long, a little technical but not too difficult. Hit a loose rock, his tube exploded and it popped his tire off his rim. Rim hit the pavement, bike ground to a halt pretty much instantly and he was thrown to the ground at high velocity. Broke his pelvis, had surgery last week. In a rehab hospital right now, should be home in a few days. He is the one that organized our Death Ride training group, so it's a shame after all that work for months that he will miss the ride. He has a good attitude about it, though.
I was talking to MBR about the crash, is this what he meant when he said the tubeless tires made him a faster descender because he has more confidence in his equipment? The answer is yes. I was asking him too if this kind of thing could happen with tubeless tires, he said effectively no. He thinks it would take about a one inch cut in the tires for them to suddenly deflate and even then it would not be as instantaneous as Hillclimber's experience. His feeling is you could maybe get it down to 15 mph before you crashed, way better than suddenly crashing at 35-40 mph. Not sure if he's right, but I hope so.
Of course not trying to talk anyone into tubeless. There's a lot of factors that should be weighed and this is just one of them. But food for thought, this is an interesting aspect of tubeless to put on your list of things to consider when making a decision.

Until identical circumstances are used, I don't think the conjecture about the added safety of tubeless can be measured.
As a counterpoint, I would suggest that the failure of the tyre wall in both walls would be catastrophic and that the sealant would not be able to seal the resulting hole. Unlike MTB tyres, road ones are running at higher pressures.
Whatever the comparisons, a high-speed bike crash is nasty, whichever way you look at it.

We returned last night from Vancouver Island. What a revelation that place has been, cycling-wise. Machka has ridden there before, and also suffered a separated shoulder in a fairly serious randonneuring accident.
Victoria was fantastic for its bike culture, and whereas I thought Campbell River in the north was a lonely one-horse outpost, it's actually a pretty busy city; we did a 50km ride along the coast southward from CR, and it just seemed so... easy (flat, no wind, great shoulders all helped).
We stayed with some bike-o-phile friends in Naniamo the night before last and caught the ferry back to the mainland yesterday in time for 50th wedding anniversary (Machka's parents) and various birthday celebrations last night.
Our Nanaimo friends are randos, too. They also have a tandem Greenspeed, and a single Greenspeed, as well as various other bikes. We told each other rando stories for most of the night. A good time had by all!!
I got on the scales this morning. Uh-oh...

?? I ride my road tubeless at lower pressures than my road tires with tubes. What do you mean road tubeless are run at higher pressure?
I do try to be very balanced in what I write. But to be clear on what happened with my friend who crashed. Both walls did not fail. His tube exploded and blew the tire off the rim. My friend who feels the tubeless are safer is a young guy who races. He only does climbing road races, so he is very aggressive with descents. He is an outlier amongst your typical BF cyclist for sure, no doubt about that. He worries about tube failures on descents (perhaps needlessly, I am just relating one person's opinion). Personally, I like the cornering much better with the tubeless, which is why they made my descending better.

I am having trouble understanding how a tube explodes within a tyre, unless there is damage to the outside of the tyre to cause it, such as in this case, the bead being broken by the impact with the object on the road, perhaps. The key issue here for me is what the rider hit with the tyre/wheel to cause the failure. Is there damage, for example, to the rim?
It's just a discussion point. I am not going to convert wheels and tyres on 15 bicycles when I haven't sustained significant puncture or blow-out issues in, like, forever. Even on my MTBs.

Comments however:
1. He is a big guy, 200+ pounds
2. He is a knowledgeable guy, works full-time in a bike shop as his primary avocation and has for years
3. He usually has good stuff in good repair
4. His bike is at the shop he works at and he has not changed his story even though they have checked the bike out for him and I've asked him follow up questions about the state of his bike
5. He has bigger fish to fry right now than worrying about the bike, so has not necessarily given it much additional thought
No one actually advocated that people should change tire types based on this one experience.

Lol, actually not defensive. I am just trying to relay accurate information because my implication was that people should consider this type of incident when evaluating whether tubeless tires make sense for them. So if my friend is an inexperienced cyclist who might not know what happened to his tire or rides crappy stuff, that's a different matter entirely. I guess I would characterize my responses as an attempt at being responsible and non-alarmist, rather than defensive.

I had these tires for a short while. I loved how they rode, but they had a tendency to blow off the rim and have sidewall blow outs.
The issue was not because they had tubes, it was because they did not seat well on the rim and have thin side walls.
