Ultra-light weight (55-60g) butyl vs TPU inner tubes?

[Catagory6]

i've been looking on line to try and find comparisons, and it seems like everybody is comparing TPU tubes to standard (100g) or even heavy-weight (120g) butyls.
aside from my disbelief that people actually run these inner tubes in their performance road bikes, these comparisons seem purposely skewed.

i've never actually used ultra light wieght butyls. mostly conti race lite (72g)

not only am i interested in a more reasonably balanced comparison of TPU and butyl, but i was wondering about the durability of ULW butyl tubes as well.

thanks

Run latex and carry tpu as repair. Tpu rides like absolute crap and the people that deny this obviously have no real road riding experience. Lightweight butyl is the worst of all worlds.

Which light butyl would support 28-30mm width-as-measured tire?

IMO - Latex is superior in both speed and ride quality to both TPU and Bytul. I do carry Continental Race Lights or Specialized Turbo Talc's are spares as latex tubes can be finicky to install on the side of the road.

TPU tubes - at least when I tried them a few years ago were hard to patch, making them essentially $35 disposable tubes.

Extra lightweight butyl is puncture prone, loses air quickly AND slow.

This. Also when I tried RideNow TPU tubes the failure rate concerning leaky valves was far too high. I went back to latex and don't regret doing so at all.

only 2 times i've tried latex, they tore a hole right at the valve stem on the first ride

i also ride carbon rim brake clinchers

I'm on rim brake carbon wheels, and I'm concern about heat on long hill descent...
I've heard they could explode/fail with heating.
That's the reason why I do not use latex tube but light butyl tube.
Am I right ?

NB I don't use TPU neither because of the difficulty to patch them, and I fear of having 2 punctures on a ride (And I don't whant to carrry 2 spares)

thanks for your thought

Park Tool patches have been fine for me when I've used them on TPU tubes.
2 spare TPU tubes take up way less space and weight than 2 butyl tubes.

I am n same stuation, and using Panaracer R-Air light butyl tubes. With 60mm valve they weigh around 75g. I ride 165g Panaracer Gillar tyres, so total weight is even leas than gp5000+light tpu.
Just too worried using TPU tube on 15km long mountainous descent at +35 degree Celcius...

Is it genuinely that noticeable? I've never run latex but considering it after running TPU this year...

Yes. But I'm running 25's. It won't make as huge a difference on super wide rubber I don't imagine.

I'm 25F @ 80PSI and 28R @ 73PSI... what do you reckon?

I agree with you on this. I was messing around with Latex and TPU earlier in the year and was racing 25mm Challenge Criterium's (on TPU) and they felt slightly harsh, went to latex and didn't look back.

However, I popped those TPU tubes into my Strade Bianche's in a 30mm width and they didnt feel harsh at all but I am running these at around 55PSI compared to 75-80PSI in the Challenge's

I have been running lightweight butyl tubes for years, 80g ones. Since I've switched to tpu (36g ridenow) I've noticed that the ride quality is noticeabley worse, to the point that I feel like I'm waisting nice cotton tires.

I've ordered thinner ones (24g ridenow) so hopefully they'll feel better, although I doubt I'll be putting them on before spring as I don't want to risk punctures in cold weather.
