Bontager’s TLR sealant is Trek Bicycle’s
first choice for tire sealant. Bontager’s TLR
is made in the USA with an ammonia-free
formula and is claimed to repair puncture
holes as big as 1/4-inch. It’s also claimed
to work in a range of temperatures from
- 5 degrees Fahrenheit up to 120 degrees.
Bontrager TLR sealant can be used in
smaller quantities than other sealants and
sells for $25 for a 32-ounce bottle.
Caffélatex tire sealant from Effetto
Mariposa is a carefully formulated latex-based sealant with microscopic particles.
The ultra-small particles clump together
to seal punctures and are claimed to work
well with thin-walled tires. Caffélatex was
designed to turn into a foam during tire
rotations to allow better coverage around
the inside of the tire (as opposed to liquids
that are slushed around the outer diameter
due to centrifugal force). Caffélatex will
then return to a liquid form after sitting for
about 15 minutes. Effetto Mariposa sells a
1000-milliliter bottle (about 34 ounces) of
Caffélatex for $30.;
Pumped up: Our
tires were all set
up with the manufacturer’s recommended sealant
amount, and then
we pumped up the
pressure to 40 psi.
The wheels then
sat for two weeks
All by hand: We used our trusty Topeak
Booster pump to seat our rims and tires.
All eight tires made a loud, audible popping sound that ensured us they were
properly set up.
Labeled: We wrote the name of
each sealant used in our tires to
