Didn't work at least once. https://cimg2.ibsrv.net/gimg/bikefor...92f33b2f31.jpg Next time I put on new tubulars, I'll cut one open to see what it's like. Here's one that didn't use any sealant. https://cimg1.ibsrv.net/gimg/bikefor...5ad4df7fe1.jpg |

Pulled out my fixed gear bike to ride today, and lo and behold, the rear tubular tire was flat. No sign of a sealant leak, so I couldn't determine where the puncture is. Nothing fancy; just a YJ "3 for $50" tire, but I've had good luck with those. This one is on its second or third season and still has decent tread. Felt like riding rather than dealing with it, so a swapped the tubular wheels for clincher wheels and went for a ride. When I got back, I squirted some more Stan's inside (not easy, as the valve cores aren't removable), pumped it up, swished it around, and still no obvious sealant leak. I'll keep checking, and if I find it, I'll position the wheel with the leak site down, so the sealant can pool there and plug the hole. Otherwise, if it's still holding pressure tomorrow, I'll put it back in service and hope for the best.

My understanding is that early formula Stans was not kind to latex tubes. But nowadays, there is nothing to worry about.

I've read that Caffélatex is good for latex tubes, it produces a foam. You can buy it in a little 60ml pouch that fits in a jersey pocket.

Day before yesterday had a flat out on the road on a tire that looked totally 100% good, and has been reliable. About 7 miles from home, and all I found in the tread were a couple of very small, almost imperceptible cuts in the tread with nothing to extract.
The old bottle of Stan's liquid latex was in the backpack and a very old spare. No glue, no tape. Long story short = The liquid latex did not work, even with a 2nd larger shot of liquid; but the old tubular held out til home, but went flat soon thereafter. I will post mortem this flat tire rather than just pitch it, to find what took it out so catastrophically and irreparably. Luckily my wakeup call to be prepared with better spare and tape to hold it in place. Luckily I had a bunch of CO2 cartridges as I kept trying the Stan's, before going to spare tire. Remember, after so many miles, those trusty old tires, ain't so trusty. |

I don't use Stan's or any equivalent but I did start carrying more cartridges after have 2 flats (with replacement tube) and a loss of air during one 11 mile commute to work. Didn't want to be late. Fixed it at the desk later in the day and used my pump to get it good enough to get to work with 4 stops to pump up far enough and riding on the handlebars to reduce weight on the rear tire. Semi-slow leak.

Did Tire Alert do your tube replacement?
I have used Tire Alert. Great way to salvage a good case with good tread. They replace the tube and sew it up. Looks great when you get it back. Some people save up their flats and get a discount with bulk service. |

Help me as I am not having fun riding clinchers!!!
I have been riding with tubulars and being a big lad, I kept having to get them trued Any bump and spokes would loosen and back they'd go. Ye local wheel builder said my rims (Nisi) were too light and that I needed a more rigid wheel. To that end I have acquired a 40 hole rear hub and a 36 hole front hub for the next build. I'm trying to find a strong 40 hole tubular rim. I've even looked for tandem rims but no luck. (I did buy a 40 hole rim only to have a 48 shipped to me and that 48 was a very light weight track rim). I'd like to use tubulars for small scale touring as well Anybody have any specific rim they'd recommend? And a source for such a rim??? |

Purchased a 70s Motobecane Grand Record with Conti Giros on Mavic GP4 wheels/Campy hubs. Thought for sure I would need to replace them, but turns out they are in great shape. Verified by quick 20 mile spin. Where do they fall in the hierarchy of tubulars?

Oh oh!
I just went to the Mavic site and it seems that they no
longer make tubular rims. I built wheels with these and they do crazy single track stuff without needing truing. https://ciclicorsa.com/shop/ambrosio...s-tubular-rim/ |

If you are wanting to dip your toes into the waters of upper end tubulars, this could be your chance. This is the second time through for these with no bid first time around. I am well stocked else I would not be sharing. |

I just intended to find a brand that made 40h tubular rims because I've hardly seen any, thinking you could search on Nisi Campione del Mondo 40 hole tubular and see if you could find them anywhere. You might try some professional wheel builder sites and just ask them if they can get such a rim for you.

Thanks all!
Have one NOS GPS 4 is sight (well in Toronto anyway), another fellow selling bike stuff on FB told me he gave away 3 40 hole rims as no one wanted them! He might be able to get one back and lastly [MENTION=297217]bertinjim[/MENTION] found one in France that's 48EU + shipping. Good times beckon! |

[MENTION=447897]johnnyace[/MENTION] - Conti's Giro tubular is the low end of their offering. Like you, I bought a wheelset with older Giro tires (23mm) , but in seemingly good shape. Put several hundred miles before the rear tire started to show some sidewall concerns. I replaced it with a Veloflex 25mm. The Giro front tire is still going strong. [MENTION=397345]Classtime[/MENTION] is right about a stiff (harsh?) ride but at 23mm and cheap what should one expect?!? I find Vittoria Rally's cotton casing to be a smoother ride, but it does not have the durability of the Giro, and - at least in the past (in my experience) some of the tires were 'lumpy'. Buy 3 = 2 would be OK, 1 emergency spare. All the tires I buy new are the more expensive ones from several companies. Liking VeloFlex and Vittoria, with Conti a close third. Bought some Challenge Elite ( from a BFer ) and will try those soon.
On a different note - have several bikes with really worn tubulars. Glued up a Conti Sprinter 22mm, Vittoria Corsa 25mm and VeloFlex Arenberg 25mm - but Holy Crap - forgot to pre-stretch any of them. The Arenberg was easiest to mount, the Vittoria Corsa was hard but doable, the Conti Sprinter would not go on. It is now on a rim stretching and will need new glue. https://cimg9.ibsrv.net/gimg/bikefor...83cae0ed6.jpeg Almost done with the last can of mastik - I will soon be a tubular tape guy. :thumb: https://cimg3.ibsrv.net/gimg/bikefor...d1472dd64.jpeg |

I have experience with Stans and OrangeSeal in tubular tires with latex - sized 24-28mm (the 22mm & 30mm are butyl tubes) from VeloFlex, Vittoria, Specialized. Approximately 1 ounce of Stans in new tires kept me flat free for 4 years, road with some mixed surfaces of trail.. Maybe that was Lady Luck, low mileage across several bikes, or Stans -- certainly the Stans seems not to have degraded the latex tubes ability to hold air, over 4 years.. As the Stans got used, I bought a large bottle of Orange Seal. I squirted it into the higher mileage tires annually. After all, I had been flat free, must work. :) :foo: Problem was that monitoring the amount dispensed from a 20oz bottle proved difficult.. [Stans had been in the 2oz bottles]. The valves got a bit messy and after a couple of very recent flats on worn (but not worn out) tires I cut open a VeloFlex and found a mess inside the tube. No way to diagnose the cause of the flat. Outer tread showed no obvious cuts or lodged debris. I guess there is a chance the combination of Stans initially and OrangeSeal subsequently degraded the latex tube, but more likely something from the gravel trail i had been riding. My new philosophy after 4 years experience with sealants in quality tubulars is this: 1. Do not use sealant in new tires. 2. Carry a small and measure-able quantity for roadside repairs - such as 2oz bottle. 3. Use sealant sparingly 4. If the sealant does not work roadside, be sure to have a spare tire. :thumb: 5. Carry tape to avoid problems with pre-glued spares. edit: and don't let your stored sealant in the bottle(s) get more than 2-3 yrs old even when stored in a basement. |

like [MENTION=22396]Wildwood[/MENTION], I have been using Stan's in tubulars for several years without problems. Not fancy tires, thoug; just YJ "Servizio Corse," Hutchinson "Tempos" and such like. But it can be tricky getting Stan's into a tire that lacks a removable valve core. At home, I use a syringe and plastic tubing pressed over the valve stem, and a needle-nose pliers to lift the knurled nut to open the valve while I inject the sealant. That's too much stuff and bother to carry on the road, so I bring a spare in case I flat.
That said, has anyone tried this Velox stuff? It's in a pressurized can, with a chuck to fit onto the valve stem. I picked up a can, just to see, but haven't had an opportunity to use it yet (nor am I in any particular hurry to do so :innocent:): |
Clarification of my above.
I have only used liquid latex type sealants listed as appropriate for tubulars and inserted into valves with removable cores (removed, then reinserted). And I have zero experience with newer tubeless rims/tires and sealant. And no intention to go that way, at least on the road bikes. |
