Latex tubes?

Guaranteed.

For me, using tubs has primarily been the ease with which you can change a flat compared to a clincher. And knowing there's no pinch flats, no thorns still stuck in the tyre etc

Special Turbo Cottons, though, not the regular ones we get.

Thanks for ruining my day

We'll have access to them soon, right? Don't we have to?

I’m pretty sure they are off the shelf Turbo Cotton Hell of the North clinchers in 28mm width. So they are available to the general public.

Surely you are wrong! We must go tubeless and need foam tire liners and sealant 😜

Spoiler in your header:(

This seems weird to me. I have a hard time getting tubulars off, and don't think it's safe cornering hard on a newly installed tubular such as after a change out on the road.

100% agree. There are plenty of cases for tubulars (like being able to ride on a flat), but ease of change isn't one of them. Especially because it's always a full wheel swap anyway. No one is changing tires/tubes in the pro peloton mid race.

laugh if you want, but that combo has already won a flanders week spring classic. the chief complaint of pro cyclists when considering anything but a tubular is safety after a high speed flat, and the ability to ride a flat until a new wheel shows up. it seems to me the tire liner solves this. i don't know. i have a set of these, i assume you don't, i'll report back what i find.

Tubular tires are very easy to remove. Use a razor blade to cut completely through them, stick your finger inside, and peel it off like a snake.

After installing your spare tire, just go around corners slowly.

Tubulars pinch flat plenty. Often as easily as clinchers. Pros flat tubulars all the time. Most of those are pinch flats, not punctures. Better yet, watch cyclocross pros -- almost all on tubulars, and pinch flatting regularly.

Anyone who argues that tubulars won't pinch flat doesn't understand how a pinch flat happens.

Me too. Though I'm a TTer/stage racer, I think they make perfect sense for that. In a pure TT or stage race TT as soon as you flat you're effectively in last place. Often in a stage race with time cut enforcement, you're headed home.

These would theoretically let you ride to the finish. It might be 4-5 MPH slower, or whatever the rolling resistance hit is, but it'd be nice to get to the finish instead of walking the last 2-3 miles (or whatever) to the finish uttering random profanities.

Even with tubulars I'd typically walk as not being a pro I don't even like to ride on barely-protected tubular rims. While a well-glued tubular won't come off, it can sort of get pushed to the side while cornering, exposing rim to asphalt at times.

If these truly protect the rim while flat, they're compelling.

It would be nice (and useful) to know the effects, if any, on rolling resistance for the liners. The claim is there's little affect, but I haven't seen any actual data one way or the other.

Oh, and I haven't forgotten about those Schwalbe Urethan tubes you sent me...I just haven't done any roller testing lately ;-)

is that indeed confirmed? asgreen was not running latex tubes? and was using the pool noodle things?

not this year. gent-wevelgem 2019. kristoff. what has happened in the interim i don't know. kristoff had 3 podiums last year in 1-day races, including tour of flanders, and he won the 1st stage of the TDF last year. was he using them then? don't know. perhaps i can find out.

Well I've heard of tyres popping off the rim, but I flatted in Cairns 70.3, hilly route with tight corners and the tyre had tape, no glue. The replacement had no tape, no glue, nothing and was fine. All it had was a slightly tacky residue left behind from the dead tyre. So no idea how people are losing glued tyres? I now glue my tyres, but carry a razor blade.

I did a video of me changing a tub in 46s to show how quick it is. I'd take more time in a race to make sure it's seated right, but still 46s is a lot quicker than you could change a clincher.

Another advantage if with some tubs you can ride flat at a decent pace. No way with Corsa Speeds, but my Conti Comps you can ride when completely flat. Luckily I've not tested this, but overtook a guy in IMWA, I could hear his rear making a funny noise and as I passed him could see his rear was completely flat. It was a Conti Comp. Had a chat with him and he'd had 2 flats and was all out of tyres, had been riding at 30km/hr for 40km with a flat. It would have been race over with a clincher. He was cooked though and had to run/walk the marathon.

Yup you're right. I'm referring to when the tube gets trapped between the rim and tyre when you change it. You inflate it and it pops. Obviously if you take your time this won't happen, but it can happen in a race when you rush it. Not sure what type of flat you would call that.

I'm not totally pro tubular and anti clincher. But there seems to be a lot of urban myths about tubs however. I've had dramas in races with clinchers, I haven't with tubs. And I like the fact that if I flat multiple times and am out of tyres I can still finish.

Installation error.

I won a bike race after riding several miles on a flat tubular.

I think ST needs a 3 day moratorium on spoilers in the headlines. I stay off of twitter and FB because most of my feeds are cycli g related. ST is where I can count on a safe perusal of the internets until I know the winner (unless I care to open the threads marked spoiler).
