Difference Between a Bike Tubular Tire and a Bike Clincher Tire

By Steve James, March 12, 2010 7:48 pm

When debating what the differences are between a tubular or clincher tire the more knowledgeable person may reply that there is a right time for everything. Knowing which one to choose is the question.

Fundamentally, the way a clincher tire is secured to the rim of a bike is by using air pressure. This is how the wheel gets the name of “clincher” by pneumatically sealing the tire between the outer rim bead and inner tube. The tube itself is completely separate from the tire. The largest example of a clincher tire is a drag radial as used by fuel cars.

Fueler teams have known for many years that for ease of maintenance and safety at high speed, it’s difficult to beat a tube that is independent of the tread. The main reason that passenger car tires do not have separate inset tubes is that in sustained high-speed, heavy-usage applications, a separate tube can rub on the inside of the outer tire, creating friction and heat-softening the rubber. Bicycles don’t have this problem as they typically run at much higher air pressure, and have a great deal less load to bear than a passenger car does.

A tubular tire is far more similar to a car tire, that is, the air containment chamber and the outer tread of the tire are integral to each other. The differing features between a bike tubular tire and a car tire is that whereas the the car tire is fastened using the same technique as a clincher wheel, the bicycle tire is stuck to the wheel rim using glue. Once the only performance choice for a cyclist was the tubular tire but with the progress in tire and wheel mechanics plus the acceptance of clincher wheels as a performance tire option within the racing community, the clincher wheel has now become the leading tire choice within the world of bike racing.

Reduced weight is the only real advantage of tubular wheels over clincher wheels because this type of tire does not require a thick rim to enable the seal. However, racing cyclists today are happy to use a clincher wheel made of a light alloy and composite material because of the ease of maintenance and greater reliabilty even though there is a small weight difference.

How To Take Young Children On A Bicycle Tour

By Nancy Sathre-Vogel, March 6, 2010 6:53 pm

You don’t have to wait until your children are grown until heading out on a bicycle tour with them. Small children will enjoy the tour just as much as you will, although it will be a very different experience for them than for you. You can take a bike tour with small children – and have a variety of options for how to carry them.

Trailers: There are many trailers available for hauling young children behind your bike and these are great for kids up to about age five. Until age 3, they are the only option possible, but some kids prefer trailers to other means until a bit older. Pay attention to the needs of your child when making the decision.

Trailers are wonderful in that children can sleep while you are pedaling. While awake, they have the choice of watching the scenery or playing with toys. Plus – you can use extra space in the trailer for additional gear.

Trailer bikes: Starting at age 3 or 4, you may be able to transition your child onto a trailer bike. A trailer bike is a one-wheeled contraption that hooks on to your bike, and has the advantage of allowing your child to help you pedal.

The downside to a trailer bike is the lost efficiency – the connection system simply isn’t as rigid as a tandem so you will be wasting a fair amount of energy hauling the trailer bike. Also, if you get a cheaper, one-gear trailer bike, your child will not be able to help pedal up hills.

Tandem: A tandem is the vehicle of choice for kids that are big enough to stay seated and pedal. They are much more rigid and efficient that trailer bikes, but are also much more expensive. On a tandem, you are teaching your child proper cadence for pedaling and road safety techniques.

In order to extend the life of the tandem, you can buy one that is very large for your child and put a “kiddie crank” (child stoker kit) on it. The kiddie crank raises the pedals up to where his feet are and can be lowered as he grows – until you take it off completely. In this way, your tandem can fit you both for many years.

Coupler with child’s bike: Another option that is fairly new on the market is a coupler that can attach your child’s bike to yours. Using either the Trail Gator or Follow Me coupler, you can tow your child through traffic or other tricky situations and then unhook his bike so he can ride on his own when safe.

Getting kids out on a bike is a great experience for all involved and you’ll have wonderful memories of your time together.

Fixed-Gear Bikes For First Time Buyers

By Jimmy Hansel, February 26, 2010 9:23 pm

Bike riding is not just your average activity. In fact, there are people from all over the world that use bikes as a simple mode of transportation as well as a way to save money. Fixed-gear bikes have become increasingly popular among those who live in the cities and urban communities. Many college students can be found riding these around campus. In order to make sure that you buy the right fixed-gear, ensure that you look over this helpful guide!

It is important that you purchase a bike that is going to be the right size for you. You do not want a bike that is so tall that you can barely reach the pedals or so short that you feel like you are on a children’s bicycle. These bikes are measured in centimeters so make sure that you are aware of the proper size first. Measure the inside of your leg down and you should be able to know your size.

When you get our new fixie the first thing you are going to want to do is hop on and ride. However, these bikes typically do not have brakes installed and therefore may present some safety issues for you. Install a front brake first in order for you to get used to riding around with the free-wheel hub. The wheel can easily be switched so that you can ride the bike as a simple single speed rather than a track bike.

Do not break the bank when you purchase your first foxed-gear bike. In fact you can easily find a used one or even new for as little as $300 to $400. It is important that you take the time to use this bike as a way for you to begin learning your own technique. Your next fixie should be either built by you personally, or custom built over the internet. Saving as much money as you can is going to be important so that you can get other aspects of your bike cover.

Complete bikes will come with everything that you need in order to get on your bike and ride. If you order your fixie online you will need to install the pedals as well as the handlebars before you ride. Ensure that you also buy a fixie tool set in order to practice all of the maintenance on your own.

These bikes also come in a variety of colors that you will be able to choose from. Fixed-gear bikes have been known to come in bright, vibrant colors that are perfect for expressing the owner’s own personality or expression. If you want a custom color, make sure to add in this specific extra cost.

Accessories can also be purchased in order to enhance your riding quality and experience. These accessories will include brakes, pedal clips, wheels and handlebars. The handlebars on a fixie can truly be unique. Look closer at the bullhorn handlebars or the straight across bars. The accessories that you buy can be added as you get familiar with bike riding.

Looking into fixed-gear bikes is a big purchase to consider but it can be well worth the money. If you are serious about learning the ways of the fixie, make sure to get a bike that you can handle and ride on a daily basis. Start out slow and from there you should be hooked on this type of bike for life!

Which Mountain Bike Framing Materials are Best?

By Paul Koons, February 4, 2010 3:36 pm

You will find the cost of a mountain bike frame to be in direct proportion to the a) material used in the construction and the b) treatment that material has received. As you begin your research for a mountain bike frame you will soon learn there are five types of materials used in the construction – a) high tensile steel, b) chromoly steel, c) aluminum, d) titanium, and e) carbon fiber. In addition, tubing material treatments adding to the increased cost of a frame are a) oversized diameters, b) heat treating, and c) butting.

Lower priced mountain bikes frames are usually constructed with a very durable alloy known as high tensile steel. High tensile steel has a large carbon content so it is less stiff than chromoly steel. Because of this, additional material is necessary to ensure that this frame is stiff enough to be used in bicycle frames. As you can guess, this process makes the bicycle relatively heavy.

Relatively inexpensive to produce, you’ll find high tensile steel in trail bikes, city bikes, and even entry level mountain bikes. There are some bikes that come with a chromoly seat tube, while the rest is high tensile steel.

Short for steel alloy, chromoly (chromoly steel) is best described by its major additives – chromium and molybdenum. This is probably the most refined framing material, giving over 100 years of dependable service.

Dependent upon the kind of heat treating and butting, you may see this material contained in bikes from as little as $400 dollars on up through and beyond $1500. The chromoly steel used in the manufacture provides excellent durability and a compliant ride characteristic.

For the past 15 years, aluminum has been refined in pretty much the same way as chromoly. There have been various alloys developed, as well as heat treatment, oversizing, and butting. With dual suspension bikes, aluminum is the preferred material as it’s the stiffest and most cost effective.

Aluminum is stiffer than chromoly, and therefore it will crack before chromoly. Of course, this depends on how you ride and how much abuse you give the frame. The advantages of aluminum is that the frame is very light and very stiff through oversizing or butting.

Even though titanium is somewhat exotic, the prices for this material have come down over the last few years. Frames made of titanium remain expensive because it takes longer to weld the tubes to the frame.

Small amounts of aluminum and vandium are normally mixed with titanium making it an alloy and improving its weldability and ride characteristics. Providing enhanced fatigue and corrosion properties, titanium is more compliant than is chromoly.

Regardless of the frame material you choose for your new mountain bike, a big factor determining its life and longevity is where you ride and your riding style. If you take care of your mountain bike and treat the frame with respect, most frame materials will last for years.

Mountain biking is a wonderful sport and will take you places you’ve never been to before. Now make sure you return to where you started with a GPS Garmin Watch. The Garmin GPS Watch such as the Garmin Forerunner Watch is going to make sure you don’t get swallowed up by the wilderness you set out to conquer.

Finding Free Bicycles – It Can Be Done

By Garrett Brock, January 21, 2010 5:27 pm

Nothing beats free! If you want a bicycle, now you can pick one up without having to pay anything. You just have to know where to look! Many people give away their bikes when they don’t want them any more. Some people even toss them in the trash.

Every year, people give away their bikes because they don’t need or want them anymore. This year you can be the person that benefits from someone else giving away their used bike.

The Internet is a great place to start your search for a free bicycle. There are two web sites in general that should be checked for bicycles that are being given away near you. Of course, you’ll find much more free stuff being given away than just bicycles, so you should definitely check these out even if you don’t want a free bicycle!

The first web site is called Freecycle.org. There you can join the group for your area and see what is being given away for free. Depending on where you live, you can often find someone giving away a bicycle they no longer want. Everything on this site is being given away for free. This site is a good place to get rid of some stuff you don’t want also. If you have a bunch of stuff lying around that you want off of your hands, you can give it away on Freecycle.org.

Craigslist.com – it’s such a simple web site, and it’s so popular that, depending where you live, you should be able to find a free bike that someone is giving away near you. After you select your area on Craigslist, look under the “For Sale” area for the “Free” section.

Check those two sites often and you are likely to find someone giving away a free bike, (unless you live in the middle of nowhere!).

For extreme toys, alternative transportation, and human powered fun, check out ActionIsle, a web site filled with the latest and greatest, scooters, electric skateboards, cycles, sleds, luges, watercraft and more. This and other unique content ” articles are available with free reprint rights.
