22mm.Continental Sprinter 100/105
23mm Vittoria Corsa 100/105
25mm Vittoria Corsa G+ 95/100
27mm Challenge P-R 90/95
28mm Veloflex Vlaanderen 90/95
32mm Dugast Pipistrella 55/60
34mm Tufo Flexus Dry 55/60

I just wrote to Veloflex. I told them how much I love their Vlaanderen model tubular tire, and asked them to consider reissuing it. I encourage others to do so: https://www.veloflex.it/en/contacts
EDIT/UPDATE: I got a super rapid response from Veloflex just a few hours after my initial contact. I've copied their response below. Does anyone have any experience with their ProTour Gum model to share?

Thank you for contacting us and support our brand!
We’ve upgraded all our tires range, did you already have the opportunity to try the new ProTour 28mm gum? It’s the newer version of Vlaanderen and offers even better characteristics.
We wish you a good day!
Best regards,
Veloflex Team.

Tubular forensics:
For those who haven't dug this deep, this shows common demise of older tires, especially CX ones that have had sealant added.
the latex has rotted at the valve from sealant, pump oil, or other contaminants. There is a 3" long glob of hardened sealant about 3/8" thick. This was a Grifo on older race wheels- it held air 6 or 10 months ago.
Additionally, I'm patching another tire & the puncture happens to be an inch away from a previous puncture repair done several years ago. The base tape was re-glued with Mastik,
& pulling off the re-glued section and the originally glued section felt the same, so I conclude that Mastik rim cement is fine for re-gluing base tape.

How old was the failed Grifo. No race season this year so I assume at least a year and a half old. I'm hoping considerably older since I have 3-year -old tires on my 'cross bike.

The tires were pretty old- I bought the wheels used I think 4 years ago with the tires on, & have used them occasionally. Prepping them to re-glue.
Don't know what sealant but I've seen the same globs in other tires so whatever they were using years ago. I've used Tufo sealant, which performed poorly,
and Stan's, which is OK, also Pitstop once. I've concluded that using it prophylactically is not the best idea, and have gotten away from using at all, but I get few flats- might be different in a more thorny area.
Butyl tubes make it less sensitive but my experience has been that road tires seal sort of but not really dependably so why bother. Lower pressure tire have a better shot at working.
I ride on the road mostly on Sprinters, which are remarkably durable IME, & worth the trade-off of being a bit less supple.

My plan is to use Continental Revo Sealant with some new Sprinters. From your experience, can the sealant be refreshed in tubs or do they render the tire useless after say a year? Just wondering if using preventively runs you through sewups before their tread is even gone.

Adding more sealant may eventually make globs inside the tire, but NBD. Most of the issues that I've noted have been on older tires w/ latex tubes that have sat around for periods of time.
Your plan sounds fine- let us know how it goes.

Yes. The Sprinters (actually using regular and Gatorskin) I know use butyl tubes. Because I will be using other wheelsets I worry that the sealant will glob up or dry out when I don't use them enough. I will spin them quite often.
One reason I am going to try the Continental Revo is that I am hoping Conti tried it with their tires, may have some insight, and if a problem develops, maybe they will address it. Could be wishful thinking though.

The only issue I've encountered with sealant in tubulars is that the valve core can get gummed up. I've seen this with Stan's and Orange Seal Endurance. If that becomes a significant issue, just remove and clean. If the tube becomes unusable and the tire is worth it, either replace it or pay to have it replaced.

Hi, I need a little help on the sizing of tubulars, I see some marked as 28, which I thought were larger by a 1/2 ", I thought tubulars only came in 700c....am I correct that they will fit on 700c or were there ever 27' in tubulars?
Thanks for the information.
Best, Ben

There were some smaller sizes for like junior racing bikes or front wheels of time trial bikes, but those would be obvious.

That's what I thought, but I wanted to ask the experts in order to be certain.

Love tubulars. Now that I have started riding again I will have to order some more bottles of flat-b-gone fluid, a.k.a. Stan's Tire Seal.

I'm typically on Sprinter or Sprinter Gatorskins on our chip seal roads. Noticed a 2 pack sale at Excel Sports last week at a decent price so I ordered a couple of 25's. I have always ridden the Sprinter 22's so I'm curious to see the difference in ride.
