Can you name a few low-weight high quality tubulars with an acceptable puncture resistance?
I'm not too concerned about the durability, or price, I'm just looking for the lowest weight without too much risk of flat tires.
I know this is a difficult compromise to achieve, but maybe there is something out there that is better than the rest.
I was thinking Veloflex Extreme or Tufo Elite S3 225.
puncture resistance depends on conditions, if the roads are wet and you'll be in urban areas where there can be tiny bits of broken glass or where sharp flints get washed/blown onto the road from verges/fields, then the water helps sharp stuff tyres cut very easily, no lightweight tyre protects against that, it is just luck whether you get a puncture or not
if roads are reasonable and you'll have dry riding it is completely different, then for really light you could consider veloflex record (c. 190g), but there's not much rubber to stop sharp bits
the extreme is only c.20g lighter than carbon, i'd go for the carbons just for a bit more durability (i live in london)
if roads are not clean and you'll have wet rides, i'd go for carbon/arenberg front/rear, they'll still cut but the extra rubber gives a bit more protection
i've tried vittoria corsa g+, lovely ride but cut very easily in the wet, i'll never buy again unless i move to a dry country!
conti comps ride like hosepipe, wet grip is good but they cut about as easily as carbons, i was surprised at that
i've got a tufo <160g as a spare, ride is nothing special, they are great as a spare but wouldn't use day to day
