Tubular clincher Tyre.!!!!

pinarellokid

do any of you guys run these type of tyre??
my new wheels are currently running theseand wanted to know some more info on them

Tufo c S33 Pro Tubular Tyre

being a clincher tub they are not glued in, and im really impressed with the idea upto now,,
may not be when i get my first puncture..

are there many clincher tubs out there for sale? seem to be hard to find,,

or are they a new idea to the market.

any thoughts welcomed, good or bad

Grill

I don't understand the point. At 335 grams each they're much heavier than my tyre/tube combo and I'd be screwed when they puncture.

Or are they designed to run on tubs without glue? In which case I'd be scared to take any corner at speed and they're still way too heavy.

link shows what they are,, seemed ok on my recent rides,,

Grill

Got it. I stand by my original statement.

pinarellokid

like i said they came on my newly aquired wheels so not my initial purchase..

being 21mm and running at upto 170psi, they certainly run smooth.

just want some feedback on the idea of them,,

looking on Plant x they seem to certainly like them..

less than 60 seconds to change a tyre

Grill

And how long to pump it up to 170psi on the road?

pinarellokid

if a roadside ump would ever get there... mine wouldnt anyway, im currently running at 110psi but i am still on the heavy side..

just wondering what to do for emergencies do i carry a spare folding tyre and tube,, or jump in and carry a spare clincher tub..

not sure which way to go.

certainly dont have any concerns with tyre coming off as its essentially a clincher tyre when pumped up.

Grill

I'd carry a spare clincher tub if you run them at 110. At least that's achievable roadside.

... I've got them on one bike... one bike only... the only rig I've got with 650C wheelz so I figured I'd "experiment".

No real feedback one way or the other from actual use. They've seen relatively few miles but I did fill 'em with sealant years ago... wonder if it still good?

I use the S3 Pro on my track bike and they work very well, and at 260gms not that heavy. Makes sense on the track as I can run very high pressures on a clincher rim without worrying about the rim failing.

For punctures you can carry a small bottle of Tufo sealant with you - squeeze it throught the valve and pump back up. You don't have to go to 170psi. You can run them at what ever you want.

Beatmaker

I don't get it. Its heavier than a lightweight clincher tyre and tube, and you use a clincher rim, which is heavier than a tubular rim. You can run it at higher pressures but I wouldn't really want to do that on a rim not designed for them, especially something lightweight and made from carbon.

StrangelyBrown

Not much heavier (they also do a 215gm tyre), and the design does not transfer the pressure to the rim so you can run very high pressures without an issue. Also means you don't have to buy tubular wheels if you don't have them, or faff with tubs if you can't be bothered.

They're not for everyone all the time, but they do have their place.

Beatmaker

Ah yes, of course the design will isolate the tube pressure from the rim. Duh! I suppose it may also remove the risk of heat transfer from braking on carbon clinchers blowing the tube.

majormantra

They aren't a new idea but according to every review I've ever read of them the ride quality is sh1t which is why no one uses them.

sungod

could never see the point of these things, poor ride quality, absolutely miserable* rolling resistance, and heavy with it

good clincher tyres will outperform these by a huge amount, you could carry a spare tyre+tube and still save weight

*even at only 30kph, running tufo hi-comps loses over 20 watts vs. veloflex carbons - tufo call the hi-comps "racing/training" tyres, and the s33 "training", so the s33 seems unlikey to be better

i've got one tufo tyre, a really light tub i carry as a get-me-home spare, imho that's the limit of their usefullness

btw to stay on the rim, surely it still is relying on pressure to keep it in place, the rim is still a clincher rim, which works by the bead being forced into the rim by the pressure
