A bicycle tube is predominantly made of Butyl rubber . Butyl is a very elastic and airtight synthetic rubber. But as with the tire, other fillers are necessary to make up the rubber compound. The quality of a tube can vary significantly depending on the rubber compound.

Where do inner tubes come from?
The tube is made out of a mix of natural and synthetic rubber . Natural rubber is less prone to punctures and is often more pliable, while synthetic rubber is cheaper. Often racing bikes will have a higher percentage of natural rubber than regular bikes.
What are inner tubes made of?
Inner tubes are typically made of rubber: either butyl or latex . Butyl rubber tubes are the most common. They’re cheaper than latex, but they are heavier and the interaction with your tyre creates more rolling resistance.
How much does a bicycle tube cost?
The average price of a bike tube costs between $5 and $9 . You can find tubes for as little as $2 and up and even some models beyond the $35. Specialized tubes and puncture-resistant tubes will cost more than traditional bike tubes.
How do bike tubes work?
The tube is made of rubber, has a valve in it for inflation, and is just the right size and shape to fit inside the tire. When you inflate most tires, you are actually pumping air into the tube inside the tire, which fills the tire .
Why are bicycle tubes made of rubber?
Why? Because improving one trait typically reduces another’s performance . To illustrate this, increasing rubber hardness boosts a tire’s longevity and reduces rolling resistance, but also decreases its wet weather adhesion, while also delivering a harsher ride.
What kind of rubber are inner tubes made of?
The vast majority of inner tubes sold for bicycling purposes are made from butyl rubber (full name “polyisobutylene”). This material is a synthetic rubber and is the most popular material type due to a combination of properties that tend to be the best overall compromise for training, racing, and overall general use.
Do tubeless Tyres have tubes?
A tubeless tyre looks like a standard tube-type clincher tyre but requires no inner tube and, once ‘seated’ (seating is the process of snapping the beads into position), it forms an airtight seal with the rim. A valve just like the one you’d find on an inner tube is fitted directly to the rim.
Do bike tubes come with valves?
Many tubes come in several different valve lengths to accommodate different wheel profiles. Most bicycle wheels are served just fine by 32-33mm valves, but higher-end bicycles are often equipped with “aero” wheels.
How long do bicycle inner tubes last?
With proper maintenance and storage, bicycle inner tubes have been reported to last up to 15 years , and the shortest lifespan reported is less than 7 days. Common factors that determine the life span of a bike tube include storage, temperature, heat, light, exposure to elements and riding conditions.
Are all bicycle tubes the same?
While your diameter measurement needs to be exact, your width measurement does not . Because inner tubes stretch, they typically come in a range of widths. For example, one of our most popular tubes is the 26 x 1.75-2.125” which means it fits a 26-inch diameter tire with a width in the range of 1.75 to 2.125 inches.
What are tubes on a bike?
The inner tube is a soft, pliable rubber donut with an air valve on its underbelly that allows air in and out . Note that a filled inner tube can appear larger than the tire. This is perfectly normal. When encased inside the tire, the tube will not exceed the tire’s dimensions.
Where are Schwalbe tubes made?
Where are Schwalbe tires manufactured? All Schwalbe tires are manufactured in Indonesia . Our state-of-the-art Schwalbe plant has more than 3000 employees who produce far more than one million bicycle tires per month. The plant has existed for more than 20 years now.
How do they make bicycle tires?
Can you ride a bicycle with a broken spoke?
“ Yes! Riding a bike with a broken spoke will not cause much harm to the wheels . However, we suggest you remove the spoke from the nipple to avoid further damage to the tires.” That said, riding the bike with only one or two broken spokes is not dangerous.
Do slime tubes work?
Slime Smart Tubes are inner-tubes containing a thick liquid which instantly repairs punctures . They work well, and are a very handy option for winter riding, but there is a weight penalty.
Do inner tubes come with valves?
Presta valve inner tube
Most bikes come with wheels that use presta valved tubes . These valves are quite narrow and have a screw at their valve tip. You need to unscrew it to get air into the tyre.
Do bike inner tubes perish?
An inner tube, inside a bike tire and not exposed to high levels of ozone or petroleum fumes (or UV light), can easily last 10-20 years .
Where are bicycle tires made?
One thing all Continental bicycle tires have in common is that they are developed in the technology center in Korbach, Germany , where they also undergo strict inspection.
What are the parts of bike tube?
- Valve caps. Bicycle inner tubes usually come with plastic valve caps. ...
- Valve stem length, valve extenders. Presta valve stems of different lengths are available, for rims of different depths. ...
- Rim hole size. The Presta valve hole is 7mm in diameter, and the Schrader valve hole, 8.5 to 9mm. ...
- Valve attachment. ...
- Ditch the jam nut.
How are bicycle rims manufactured?
The method of manufacturing the bicycle wheel comprises the steps of: preparing a mold with a compartment formed therein; laminating the composite material prepreg and applying adhesive material between the adjacent layers; applying foam material and solvent material respectively within the spoke part and the rim part ...
Do tires still have inner tubes?
Inner Liner
Note, however, that modern car tires no longer have inner tubes inside them . A tire’s beads, bead filler, and inner liner work together to hold air within the tire walls.

Are latex tubes more puncture resistant?
Coach Fred Matheny Replies: Latex tubes are usually lighter than standard butyl tubes, and their fans say they have a “nicer ride.” They’re also reputed to be more puncture-resistant because they’re more flexible.
How does a tubeless bicycle tire work?
Tubeless bike tires work by creating a seal between your bike tires and rims , meaning you don’t need inner tubes to keep air in your tires. The bead of the tire seats into the rim, then a gooey sealant product is inserted into the tire to make it airtight.
