Ok, so I am going tubular for my geared bike. I have read the threads, sought some advice and am all keyed up to give it a go but I have a couple questions.
The Mastik glue is just carpet glue right?
A spare - I am shite scared of being 100k’s from home and getting a puncture. So I intend on carrying a third tubular with me. I bought Veloflex Criteriums to go on the wheels and was wondering if anyone had an opinion on a good spare tubbie.
I am looking for something that is cheaper than the Criteriums, and folds down nice and small (if this is possible).
Not sure about the mastik been carpet glue I just buy the stuff from the lbs
Small light spare… Try a tufo jet, not much good for anything else though. They are tough and very light
I have heard this as well, but I run Stans in my MTB tryes with no problems.
Also, from the No Tubes web site:
I heard there is ammonia in your sealant and it is bad for my tire and or rim?
Any trace amount of ammonia in Stan’s sealant will evaporate soon after it is injected into the tire. We have found no damaging effects from our sealant even after years of use. Any oxidation in your rim will just as likely be caused by riding in wet conditions or the humidity in the air. Although tape may not be necessary to seal your rim, you may add one layer to protect un-anodized or scratched areas of your rim from oxidation due to moisture in the sealant.
Will using your sealant void the warranty on my tire?
Using our sealant will void your tire warranty with certain manufacturers. Stan’s NoTubes Sealant will not damage your tire.
I don’t know much about chemistry/physics/science in general, but where the fuck is the ammonia going when it evaporates INSIDE A SEALED TYRE? Any rational explanation considered.
Ammonia can be bad for alloy rims but that’s not a big deal for a tubular tire… It’s a sealed system… The sealant doesn’t fuck up the tire but it will dry out over time… Don’t use sealant in your ride home tire… As the sealant could stick the tube together.
The gator is not that soft a tire so it won’t fold so well… I wouldn’t use a tufo for anything but a ride home but they are light and thin making em easy to fold and pack. My mate has a ride home in a pocket umbrella case… Bang it in your pocket for a long ride… Easy
I’ll take your word for it. Seeing as the latex tubes in tubbies are more permeable than butyl I guess that is indeed a reasonable answer, assuming of course that ammonia molecules are smaller than oxygen or nitrogen…
Speaking of ammonia, how good is this record? #90s#oldfart
After getting a flat first ride in my tubs I was a little annoyed. A sharp bit off glass had worked its way through the tread and punctured the inner tube. After a lift home and 2 weeks of ‘I can’t be fucked trying to fix it’ I got some vittoria pit stop (google it) and that fixed that in 2 minutes flat. Pardon the pun.
I’ve ridden 3-400 on them since on worse roads without issue. My confidence in tubs for the road is growing again although I carry a can of pit stop with me on rides.
