I am wondering about spraying some Vittoria Pit Stop inside a set of Dugast mountain bike tubular tires as a preemptive measure against flats.

On part of their web site, Vittoria says don't use sealants inside tubular tires for a number of reasons -- it can harden, it's heavy, etc. But on their product page for Pit Stop, they say go ahead and use it preemptively. Competitive Cyclist on their product page for Pit Stop says it can be used as a preemptive measure against flats and that it works great with butyl or latex tubes.

It's a fluke I own these tires. If they last through the fall, that's more than I expect. So I don't really worry about the sealant eventually hardening up, and I don't care about adding a few grams. I'd just like to have them be bit more protected against a flat, and less likely to bleed pressure between rides.

Any experience with Pit Stop? Any reason not to try? Thanks

here is your best source/discussion are for tubular https://www.bikeforums.net/classic-v...y-tubular.html

I use caffelatex, in my tubulars but have a pressure can of pit stop in my bag

I had some once - didn't work, when I got a small puncture on my front tire the stuff came spewing out and got on my sunglasses, bike frame, brakes, etc.
I've had a little more success with Stan's - worked well enough once to get me home on a soft tire.
If I had more flats I'd be more interested, but I'm fortunate not to have to worry too much.

I have been using tufo sealant for years. Hasn't let me down yet. Sealed a nick a couple of mms long a month or so ago. And I'm still riding the tyre.
It does clog the valve but they can be cleaned or just force the air past.

Thanks for all the advice -- I'll give it a go, since it's what I've got on hand. If it results even in the tubes holding air longer before fill ups, that'll be good enough. Next time, I'll get something else.

Pit Stop is sealant and compressed gas to fill the tire- if you're adding it ahead of time just use sealant.

I tried it once- actually found a whole saddlebag road-side with a tire & can of pitstop. As I recall, it sort of worked,

but not enough to buy another and carry it around.

So while I use the tufo I assume they all work similarly. The tufo certainly doesn't stop the tyre slowly deflating over time.
