wide but light tubular tires?

Now riding 23mm corsa speed front and 25mm corsa G+ rear, on 27mm wide Bontrager Aeolus rims

I'm thinking to try wider tires for winter, eg 25mm front and 26-27 rear to match rim.
But, all the 27mm tires seem to be around 300g, the exception being the Zipp tangent SL advertised at 275g

I would prefer wide but light if possible. My current 25mm corsa G+ are around 270g new, I just weighed a well used one that flatted after a skid at 261g. The current Corsa speed are just under 200g new

Would also like a good tread, the discontinued Vittoria Pave were a lot more grippy than the 25mm corsa G+ and not much heavier

anyone riding on wider tubular?
thanks!

wider == more material == heavier (unless it's made so thin that it has terrible durability)

as scotty said, "i cannae change the laws of physics"

Such tubs don't exist.

Not only that, but tubs also have become heavier. I had several Veloflex Extremes bought around 2010, weighing at 225g on average and Carbons at 250g; nowadays, they are 240 / 260 g respectively.

Just ride the wide ones and enjoy. If you don't want Veloflex, Specialized Turbo Hell of the North tub in 28mm (the only size) is essentially a Turbo Cotton, and very nice.

I think Corsa control is the answer for more grip. Weight is similar to the regular corsas.

Just find the old Pave's for grip.

Yes, things have gotten heavy lately with tubular tire weights
I was using old Corsa cx, the 21mm new was 245g, 23 250g, and 25 260g. In theory a 27mm made like that should be 275g

The new graphene tires are a bit heavier, and the corsa control is much heavier than the old Pave, the 28mm is advertised at 350g and 25mm at 295g. The old Pave 25 was ~275

They do have the corsa speed in 25 advertised at 205g. If they made a 27mm they should get it under 245

What kind of winters do you have considering Corsa Speed?

I have a 25mm Corsa Speed, weighs as specced. Very minimal rubber on the shoulders though so super vulnerable to cuts. The king of money-no-object tyres though, very fast and will satisfy the weight weenies too.
Veloflex Vlaanderen or Raven are sensibly light for the weight (300g).
As you say the graphene regular Corsas are a bit heavier (330g for a 28), partly because they have more rubber and partly because the latest casing material has some kevlar and is coated, rather than a lighter plain polycotton.
I have heard tell that the 27mm from FMB come up larger than that and are therefore pretty light for their true volume. But there is so little info out there that you will just have to buy and try!
Lastly I think most rolling resistance data out there suggests that you are best off choosing a company that uses a state-of-the-art compound, even if the tyres are a little heavier. Veloflexes are beautifully and sparingly constructed but there is a reason they seldom penetrate the upper reaches of the rolling resistance tables whilst Conti feel awful and ugly in the hand but are fast as all hell.

+1 for zippy speed sl in 27mm, rolls very well. Expect ~2000km for rear. I was getting them for under 50USD on Ebay. Just took off the front after ~8000km. Going back to 25mm Competitions because I'm lazy and was getting tired of pumping up the tires everyday.

A litte off topic, but I noticed you're running tubular tires that are 4mm narrower than the rim itself. That seems quite significant. How has running tires considerably narrower than the rim worked out? Do you see sections of the rim exposed or the tire not adhering well?

They are very durable winter training tyres but weight is not similar- mine weighed in @ 304g for 25mm.

I'm curious too. Maybe 27mm isn't at the brake track?

A picture would be nice. :)

Another vote for Zipp SL Speed 27mm, been using them for a while now great all around tires, they also come in a lighter weight 24mm if you want to run a 24 / 27

Its also the fasest 27mm tubular tested tire I have seen .........
