Stan’s tire sealant is one of the most
popular sealants on the market. We’ve
often heard riders refer to a generic tire
sealant as Stan’s, because it really was
the original high-performance sealant
specifically formulated for bikes. It’s made
with a low-viscosity liquid, so it can easily
work its way around a tire, and it uses
sealing crystals to patch up punctures.
Stan’s is also made with an anti-freeze
material that will allow it to stay liquid
in temperatures as cold as - 30 degrees
Fahrenheit. Riders can get a quart of
Stan’s sealant for $28 and will have liquid
to spare after their conversion.
A bottle of Orange Seal tire sealant is
generally the top recommendation from
many bike-shop mechanics. The sealant
tends to cost a little more than others
ounce for ounce, with an 8-ounce bottle
selling for around $13, but Orange Seal
is known for its longevity and ability to
quickly seal punctures. According to
Orange Seal, its sealant can patch up a
1/4-inch hole and performs well in a
variety of temperatures. The sealant is
formulated from “nanites,” which are
essentially a bunch of different-sized
particles that work together to plug up
Set ’em up: The insides of our rims were wrapped with a special tape and a tubeless-ready valve was installed. The tires were then put on by hand, leaving just
enough space exposed to pour in our tire sealant.
Single serving: Doc Blue sealant from Schwalbe comes in a small 2-ounce bottle
to fill one tire. A larger bottle can help save money in the long run, however.
Pro tip: Some companies sell injectors to allow sealant to be inserted through a wheel’s valve stem. These work well when you
don’t want to debead your tire, but they may clog your valve stem. We recommend simply pulling a small section of the bead
off the rim and pouring your sealant directly into the tire.
