tubular repair,tirealert and other musings

So, punctured a vittoria CX tubular a week or so ago. Finally found the time to put some sealant in it with no success. I thought about pulling the tube out and patching it but I don't have any spare latex tubes around. Other thing is that it looks like the latex tube might have blown through the outer rubber. So I have one hole from the puncture and one hole where it looks like the latex tube busted and separated some of the outer casing.


I was going to try and get some latex to patch the whole and restitch but at this point I wonder if it is repairable?
Send to tirealert?

Depends on mileage. I glued two Evo CX for my stinger 6 last year. The treads on the rear worn out after 600 miles, and the sealant had already sorked its magic once but didnt work on the second puncture

the front is still going strong (fingers crossed) and there's quite a bit of life left, having perhaps 1200 miles on it. So fix the front if it has tread left, and unless you have less than 200 miles on it, ditch the rear

I send them to tire alert and them eBay them. Since I only race on them I prefer to not use repaired tires.

+1.

perhaps you already do this, but just in case you don't....when you find the source of the leak it can be useful to hold your finger over it while you inject the sealant. give it a few seconds to set up. do not inflate the tire to high PSI during this time as you'll just blow out the seal.

spin the wheel (or ride) for a bit.

when you store the bike, ensure the leaking spot is the lowest point so sealant will pool there over night.

like MD says, sometimes it can take more than once for the fix to hold. could be worth a shot for you.

also, sometimes the actual leak in the tube is at a different point than where the sealant exits the casing. these can be trickier to fix.

ron at tire alert does good work. unless you are really keen to do your own repair and have the skills, the money paid to ron is worth it IMO.

Yeah, i had followed all of the above except that part and did end up blowing out the seal but I was using stans and I have heard good things about vittoria pitstop.

I will try pitstop and if not just send it to tirealert.
@echappist goodness that is low mileage. It is my rear tire but it has seen about ~1000 miles and still has good tread. I will probably just use it to commute on for awhile as I plan on building up some aluminum tubulars for the winter riding.

Was going to switch to veloflex carbons and probably still will but currently wiggle has some vittoria corsa evo sc for ~$57.

Thanks all

i'd not go with pitstop -- i'd choose caffelatex instead. (i've probably got 5 or 6 cans of pitstop just sitting here, too....i should sell them.)

once you've got sealant in the tire, esp with a nice tire that has latex tubes, you've now got 2 things going on:
1: the sealant will leak from the tube. a cotton casing will absorb this. perfect repair is now not possible. this is the reason that the owner of dugast say never to use sealant. not sure how/if ron will deal with sealant--you may wish to inquire as the repair option could be off the table.

2: the sealant can cause the latex to stick to itself (or rather for the sealant to cause the sides of the tube to collapse and adhere to the sealant) when there is little/no air in the tire. it becomes more of a maintenance issue to deal with, esp in the off-season. be advised.

i stocked up on the evo SC. they seem to hold up a bit better than the CX, though i really have no idea as i haven't logged miles as meticulously this year. that Evo CX was used for ~10 races and a few training rides last year, and it just wasn't worth salvaging at the end. So all in all, it may have had less than 600 miles on it when the tread was all gone. in contrast the EVO SC has been used for 5 races and quite a few training rides, and it doesn't look nearly as bad.

FYI, if anyone needs tires...i'm holding probably 20+ now...mostly vittorias, some other nice ones. been aging them. this tire-hoarder is realizing i have way more than i will ever need and will probably take some of them to ebay in the next few weeks, along with a ton of other parts.

umm, i'd like the end plugs to the PRO aerobars

5 yet to be glued EVO SC, plus 2-3 other still usable tubulars with a lot of life left are way more than what i'd need, though if you have a team edition Conti tubular, i could be persuaded

I'm glad to hear I"m not the only one to hoard tires. I had the chance to get some Vittoria Corsa Elite and Conti Sprinters for wholesale, so I loaded up.

sometimes I am just in the mood to buy things so I order tires, chains or cassettes. I'm pretty set for a while now!

Teton, let me know what you've got for tires. I'm down to two on the rack. You know how to get a hold of me.

So, I still haven't heard from Ron at tirealert...he is usually pretty quick on the response.


Anyway, tried sealant again and it worked this time and has held pressure fine with one ride on it now too. So, with basically one more week of racing I will probably keep it on and then switch it to my training wheels.

My epic stash of tubulars is largely gone now (maintaining 4 sets of tubular wheels over 3 years will do that to ya), and I'm thinking about next year's "needs"...

Teton, inbox me after you and shovel get through swapping rubber?

Shovel- I see you've got a new source, and here I thought we were tight
