I've got one of those big pots for tube work at home. t isn't practicla
on a ride, too big.


When the same discussion appeared in r.b.t a few years ago, I decided
that quantity might be a suitable substitute for quality. I bought
30x tubes of cheap Chinese glue at a cost of about $0.50 per tube.
https://www.ebay.com/itm/153039763013


That's the stuff used in bike shops and I've never seen them drying
up either. I suspect that the contents are different.


They certainly do dry up eventually. I leave a few tubes in my car in
the automobile tire patch and plug kit. The tubes are larger, but the
contents seems like the same glue and solvent. The tubes dry out
after about a year in hot car. I suspect that the Rema "cold
vulcanizing fluid" type adds some kind of vulcanizing accelerator to
deal with the unvulcanized rubber patch.

One thing I haven't tried is marking the tubes with their measured
weight, to see if I can at least identify which tubes are lacking
contents. Also, I've never seen a dry tube that still has some
residual liquid rubber cement left. It's always good as new, or
containing a small amount of some kind of white powder, and nothing
else. Weird.


I have seen plenty where there was still "liquid" in it but most of it
had become gooey and clumped up on when squeezed out onto the tube surface.

Do you guys know a brand that is better and where a bunch of these
little tubes could be bought sans patches? Not so much for me but
for other riders because many reported similar problems.

The cement and patch are designed to work with one another. There are
chemicals on the patch that are activated by chemicals in the cement.
Different manufacturers use different activators. You will get best
results, if you don't mix manufacturers.

I've found the Rema Tip-Top patches with their tubes of cold
vulcanizing fluid to work extremely well.


After recommendations in this NG I bought a larger pot with tube cement
and with a dabbing tool mounted inside the lid. I have used that on
various patches and it worked well. It's just way to large to carry
along in a pannier.

Be scrupulous about sealing. The 8oz cans with a brush are a great value, but they dry out pretty quickly and inevitably before a home mechanic can use them up. Nonetheless, considering the price difference between the tubes and cans, you still come out ahead even with wastage. It's like buying the big bottle of hydraulic oil -- for twice the price, you get ten times more.. You can spill half of it on the floor and still come out way ahead.

I have found that new unopened tubes last forever something that a
lot of Rema did not. Or at least none have failed in four years of
storage


Maybe this Propatch tube was just a dud then. It had the same puffy
appearance and feel to it as usual but when puntured ... phhht ... could
be compressed to full flat without anything coming out.

I still have about 70 or so of those patch kits and they are fine so it much be something to do with heat.

Huh? Wrong place for that comment I think. Though that looks like a really first rate pannier that won't hit the back of your heals while you're riding.

That can be topped:

80 liters. That's a lot of growlers.

That might be. You live near the coast where it rarely goes above 80F.
Here we have weeks in a row where it's above 100F during the day and I
ride in almost any weather. Even at 105F in the glistening sun when the
bike paths are almost empty. When I grab another bottle of water out of
the left pannier after a few hours it's really hot. Everything bakes.

Joerg said there wasn't room in his bag for a tin of cement.
The Jandd panniers could hold 90 or so tins!
