I want some. And now it is official: 25mm is Eroica.

Completely off-topic for this thread, but yikes!

i would speculate that the 240 euro price is for a pair.

when they did this 'special edition' in 2021, it was 230 Euro for a pair, but you did not get a cap with them.

the 2021 video was longer though

could very well be, so that price is not terrible

also figured out Vittoria Dugast link. Vittoria bought Dugast

Is that really a tubular labeled as "open corsa" ?

smontanaro 

Well that sucks...

I rode my Serotta out Monday for the first time since last fall. Tuesday was brutal, so I just puttered around town on my Dawes. Yesterday I rode the Dawes again. The ole thumb check on the rear tire suggested there was still plenty of air in the Panaracer Race C Evo3 tubulars, so off I went. After a few miles the front tire started to feel real mushy, so I stopped and added some air. That got me up to Highland Park, where I decided to ride down Ravine Drive to the lake. On the way back up, the front tire nearly went flat. I walked up the steepest part, then put in some more air. That got me a couple more miles, where I decided to just put on my spare. I opened the valve to let out the last of the air only to find my hands covered in sealant. Hmmm... Why didn't the sealant work? More important, why didn't any sealant leak out through the treat or sidewall? This didn't sound good.

A few minutes ago I decided to investigate. I pumped up the tire and it went flat almost immediately. Then I looked at the base tape and saw little droplets of sealant puddled along the center. Apparently, the sealant had oozed out of the stitching and through the base tape (now that it wasn't glued to the wheels. But wait, there's more...

Thumb on the front (spare) tire, feels good, about a day's worth of air leakage. But the rear tire is completely flat. I pumped it up. It seems to be holding air for now. There doesn't appear to be any sealant in the tube.

So, I'm not 100% positive, but I suspect there's an issue with the valve-stem-to-tube interface. These tires have relatively few miles on them. I think I put them on the Serotta new when I was building it up. Strava tells me I have just over 720 miles on that bike. That would be the max on the tires. I bought them from Bike Recyclery in Portand in Feb '21. Given the nature of their business, I'm not sure approaching them would be fruitful. I guess I'll just chalk it up to experience. I'm unlikely to ever buy this particular tubular again.

I swore off buying used tubulars a while back .

smontanaro 

These were NOS I believe. (I assume you were responding to my tail of woe.)

markwesti

Yes I was responding to your post , sorry to hear about your flats . I was under the impression your tires were used , not NOS . Over the years I have bought about 5-6 "used" tubulars , not one could be repaired .

Vittoria also bought 3T

I put sealant, by suggestion. In my Zipp Tangente tubulars.
Disaster, at the valve stem. Only tubular flats in years. Both were Zipps, both with sealant, both at the valve stem.

smontanaro 

Yeah, I'm familiar with sealant thinking up valve stems and am prepared to deal with it. Generally, I can clean them out, but sometimes you need to replace them. That didn't seem to be the cause for either tires' failure in this situation.

I suppose an autopsy is in order.

Classtime 

I have good luck storing my tubular tired bikes with valve stem up if they have sealant in them and I only use sealant during an event where I don’t want to use an inadequately glued spare.

I will buy used to be able to try a high zoot tire at a reduced price. Then I know if I want to pay full boat price. Excellent results so far.

markwesti

I bought a high zoot racing tubular once actually a pair , they were slicks . I really wanted these things , problem was the road surface was cracked you could only see it if you squeezed side walls together . Honest mistake I thought , ebay seller took them back .

Does anyone know where I can get a can of glue, Continental, Vittoria, don't care which? I'm seeing cans out of stock everywhere. I only see the little tubes and the littles tubes are selling for $20+!

smontanaro 

WGB I was just thinking it was time to get some more. I haven't looked around much. I do see tubular tape available on Amazon. Maybe it's time to try that...

Edit: Just found some Mastik One on eBay.

While we wait for more Mastic?
But it is scary that the Vittoria site is calling Mastic “ old school”.

WGB 

Thank you to @smontanaro as I now have some glue (or will by late next week....)

It's been a while since I had fuss with my tires. These days I just ride 'em. From today:



The tires are Veloflex Criteriums, unless my memory is tottaly uot to lunhc, whihc is alyaws poosible.

What is considered the best sealant for tubbies? I went back 5 pages and saw Stan's and Orange. Stan's seems to get good reviews in this thread.

My first sewup wheel, GP4 and 28c Corsa Control G+ is going fully flat between pump ups when I'd expect about 10 psi a night loss. Haven't spent the time to diagnose it yet. I may have damaged the valve and tiny debris is a life's curse of my riding territories. I've also thought that tools to carry sealant and use on the road might be both smart and allow riding with just one spare and still be pretty certain to be able to get myself home. So far, my life's been sealant free so I have no background here.

Also want to put together a sewup patch kit for the road. Waxed thread; perhaps the thinnest of the sail threads or perhaps pre-waxed carpet thread (pre-waxed by me), an appropriate sailmakers needle, thimble, patches (is there a preferred brand or type?), REMA cement, boot material, some carpet glue in a small tube (how to get it in there might occupy my in-bed thoughts for some nights), perhaps a few inches of basetape. Is there anything else I should carry?

I used to just buy those orange sewup patch kits and change out a couple of the items to ones I liked better. I remember breaking it out to fix my second flat of the day a long ways from home after riding out to the Longjo Memorial Criterium in Fitchburg, coming from Boston. Found a nice, comfortable spot on a grassy hillside for the work, did a good job and rode the miles home just fine. Cannot even find a mention of those kits now in my web searches.

Caffe Latex is another sealant with good reviews.
And Velox tubular patching kits are still available.

I've only tried sealant recently: Got a flat in a Vittoria Rubino after only 86 miles from a 2mm piece of glass and had to wheel it home (but only 3 miles).
Did some research and tried Orange Seal, sealed in 2 seconds and the tyre has done another 300 miles since with no problems.

Here's some testing from 2014:

I've had mixed success with Stan's. It seems to seal well enough to get me home, but doesn't always result in a permanent fix. I haven't tried Orange. Velox makes an inflator/sealant combo that may obviate the need for a CO2 cartridge. I bought one, but haven't had the opportunity to use it yet. Not in any hurry, either.

Last year, I got my first set of tubular wheels. I went cheap on tires, buying a pair of 22mm Conti Giros that were on sale. I used tape to glue them to the rims, and they've been fine. As I understand it, Giros, being cheap, don't really give you all the suppleness of the best tubulars. So, when I saw 23mm Vittoria Corsa Speeds on sale for about $30 each, I bought a pair. I realize they're basically racing tires, but as I say - $30!

So this weekend, I thought I'd take the Giros off and get the rims ready for the Corsas. I let all the air out, but I could not budge the tires. I suspect there's a trick to getting the first little bit loose from the rim, and after that you can probably pull them off more easily, but I don't know that trick! I also realized how lucky I'd been not to get a flat in the 500 miles I've ridden them, because I'd have had a hell of a time taking them off the rim to put on the spare!

Any hints, tips, tricks? Or is it just all brute force?
