Tubeless roadbike tyres

[Mr Purple]

I find TPU tubes excellent. As a spare while riding tubeless, because they take up very little space and weigh next to nothing.

I did run them for a while regularly as tubes. They seem a little fussy - nice and light and roll well, but very easy to get a small puncture while installing. Which is a pain when they're so expensive.

I've actually stopped carrying a pump on the road bike because every single mini pump I've bought doesn't actually work for pumping up tyres. Half considering one of the electric ones, otherwise carry a CO2 cannister.

I've been running tubeless on the road since 2020, but am considering going back to tubes (TPU). Tubeless was great when I was doing 7000km annually but in the last year I only did 1000km on the road bike, and it sometimes 0kms for weeks. The maintenance with tubeless is a pain for the kms I ride. Seeing I got 10000km after the last set of tyres, and have just put new ones on, it might still be a while until I swap back (if at all).

[Mr Purple]

Yep, that is one occasion I definitely wouldn't recommend tubeless.

Because I get 1500km to a tyre anyway, and do around 200km a week between my two outdoor bikes, going tubeless makes absolutely no difference to my maintenance schedule.

For an occasionally used bike or minimal mileage it would be hard to justify.

My old TCR is hanging around unridden now. Still tubeless, done about 25k km tubeless. Not worried about maintaining the sealant in it. If I ride it again I carry a spare tube anyway. Very unlikely to get a double puncture. I'll just whip the tube out when I get back and replenish then.

I went the other way and got a compact pump. Once I’m out of CO2 I’m buggered and could be way out of town. I take a couple of TPU tubes as spares. Two probably weigh as much as one butyl tube. I’ve also tried running 32mm tubeless but they felt a bit sluggish and heavy. Gone back to 28mm GP5000’s for now.

Topeak racerocket hp for a pump and a CO2 bulb and head held on with elastic band, in a small drawstring bag (glasses bag I think).
Both easily fit in a jersey pocket. Spare CO2, tube and levers in the saddle bag.

BRR's latest test results of the Vittoria Corsa Pro Control TLR 34mm

https://www.bicyclerollingresistance.co ... control-34

Seems to be matching a recent trend of completely mislabelling the width.

Measured at 31mm And tested as quite draggy !

[warthog1]

It is measured on a 17.8mm rim width. Very narrow and not what Vittoria would be expecting that tyre to be run on I assume.
Wouldn't be surprised if it measured over 34mm on my 25mm int width WR50s

Tyre widths are all designed around a nominal rim width, which increases with tyre size. As best as I can find from a quick Google search if the manufacturer follows the ISO standard, 25mm and 28mm are designed to fit a 19mm rim. A 29mm-30mm tyre is designed for a 21mm rim.

The result is a 28mm tyre on 21mm rim is only going to be marginally smaller than a 30mm tyre on the same rim.

Good info, thanks.

I have done just that with 28-30 on my WR50s, 25mm int and hookless.
The 28 was ~31 and the 30 ~31mm. Schwalbe pro ones. At least in that model there is still a difference. The 30mm are noticeably wider and come in a bigger box.
Loving the wider tyres at lower pressure.

Found this that you may or may not have seen;

Below is a comparison between the old Corsa 2.0 25mm clincher and the Corsa Pro 32mm. And yup, just as it appears both have a tread width of 30mm. Carcasses are 72.5 and 86.0mm respectively.


The tread width is rubbish there on the 32.
Not the pro control tyre though. However I wouldn't be surprised if it was silly on the 34 you linked too.

Edit; I should actually read the linked review
The Corsa Pro Control is very similar to the regular Corsa Pro, but the main difference can be found in the tread area. The tread on the Corsa Pro Control is a bit wider and thicker, comes with a different tread pattern, and is made of a different compound mix
