Bicycle Wheel

Things To Remember While Buying a Bicycle Wheel

Most Important Part Of a Bicycle The first thing that comes to mind on thinking about bicycles is the wheel. Bicycles are actually the simplest vehicle to run on a pair of wheels. To think about it. the name bicycle itself stamps the importance of bicycle wheel – it means two wheels. Innovations in wheels have played an important part in bringing out generation changes in bicycle history. High Wheel Bicycle. High Wheel Tricycle. and Pneumatic Tire Bicycle – all these developments have revolutionized the bicycle industry at some or the other point.

What Makes Up A Bicycle Wheel Although bicyclewheel seem as a simple tool to many. yet it is a combination of several small parts that work together to make a bike run.

1. Hub: It is the central part of the bicycle wheel and can be seen as the nucleus of the wheel. It is also the part where the axle gets connected to the wheel. These days. aluminum is the preferred building material for hubs.

2. Spokes: They are thin rods or wires used to connect the hub to the outer bicycle wheel. Stainless steel is used to build bicycle spokes as besides being strong. it is rust-free.

3. Nipples: They are small cylindrical sockets used to connect the spokes to the bicycle rim. Aluminum and brass are the preferred material for making nipples.

4. Rim: It is the outer circumference of the bicycle on which the tire rests. It is connected to the hub through spokes. Traditionally. steel was the preferred material but it has now been replaced by aluminum as it is provides better braking. besides being rust-proof and light.

Things To Remember While Buying Bicycle Wheel As there are several building materials available for each wheel part. one needs to know the things that can harm in the long run :

1. Hubs carved out of solid billets (using milling machines) have weaker flanges; even through they look more attractive.

2. Zinc or chrome plated spokes should be avoided as they are susceptible to rust and are also weak.

3. One should avoid using aluminum as the building material for nipples. in case the rim is also build out of aluminum. This is to prevent chemical welding from taking place due to usage of same material.

BMX Sport Bicycle

It's been on my heart to write this article for some time now. This article is written to serve parents everywhere when shopping for their boy or girl's first BMX bike!
For over 7 years I operated my own bike shop out of my parents home in Mesa, Arizona, Donnie's Bicycle Shop, and it thrills me to no end to be able to share some key information with you!
First, let's talk about BMX bike names and where you should or shouldn't buy your son or daughter's first bike. You can't go wrong with Haro. HARO BMX has been around for so long and they keep coming up with new and innovative designs. Also, Diamond Back is trustworthy, lightweight, and again, the company is rock solid. Red-Line BMX is also highly recommended.
Mongoose is my BMX line of choice when purchased from a real bike shop that knows what they are doing. Mongoose has been making BMX bikes that kick everybody's tails for years, and they make the most beautiful bikes! But your going to have to consult your local real bike shop owner, because you don't want to buy from Wal-Mart or other chain store. Also, you may want to contact Mongoose directly and request a race-bike BMX catalogue only.
My first BMX bike was a bike called the JAG BMX by Mongoose, and the bike served me well for many years. If you can get ahold of one, it's sure worth it. My first bike had a glossy cream-orange frame, with white MotoMags. I recommend Motomags. But be careful, no Motomag imitations, and there are a ton of them. The mag has to say Motomag on it.
A word about grips! Today's BMX bikes are coming out with some of the most uncomfortable grips for the kids' hands! Have the bike shop owner show you the array of grips available, and to me, a foam style is the best, or a really soft gel rubber is ok too. I always loved the foam grips when jumping because they absorb the shock of the fall!
Watch out for GT's Dyno line. The frames on most of them are not as solid and if you don't believe me, go to your neighborhood thrift store, and you'll see a ton of GT Dyno's. I personally would not buy my son or daughter a GT bike, unless it was one of their top of the line models. I also had a problem airborne with them upon landing, when compared to the awesome Mongoose BMX, my dad bought for me at the local bike shop in Mesa.
Buy your child's bike from a regular bike shop. Do not buy it at Wal-Mart, Target, Costco, or Sam's Club. These bikes carry the names Schwinn, Mongoose, and more, but let me guarantee you, they are not the real Mccoy!
That said, also watch out for high pressure bike salespeople. Believe it or not, they are out there! If they have such a good product, why do they have to pressure sale you?
Back to brand names. If you are going to buy a Schwinn, Mongoose, or other formerly well-trusted bike, deal with the company directly or a reputable bike shop in the area. You won't find any Wal-Mart BMX bikes in your local bicycle shop!
Now, as to hardware! If you're going to get your son or daughter a bike make sure you invest in ultra lightweight aluminum or chromoly rims. So many bikes out there are being sold with cheap rims and cranksets. It's worth the extra one to two hundred dollars to get your child the very best components. They will last longer and your child will have one of the best and baddest BMX bikes on the block!
That said, invest in three piece aluminum cranks or one piece aluminum, titanium, or chromoly or whatever other space-shuttle type of materials they have! Don't opt-out for regular steel cranks. Get a bike that has a lifetime or at least a twenty year frame warranty.
If you want to buy a vintage BMX bike from e-bay or a local auction, invest in the 1984 Schwinn Sting. That bike is totally bad to the bone man. Any newer versions of the Schwinn Sting should be purchased as well.
Ok, let's talk about rims. Rims need to be light. So many BMX bikes have heavy bulky rims. Rims should be lightweight alloy. Also, you want to request sealed bearing hubs because they don't require any maintenance, almost ever, and they make them on the best BMX bikes everywhere.
Also, trust your child. If they love the bike, it's the bike for them. But let them know you love them enough to request upgrades on the rims, tires, and brakes!
Also, BMX bikes should have mid-range to best brakes. Get alloy again, or high dollar brakes. This is your child's safety for goodness sakes! You know how many cheap brakes there are on BMX bikes? You don't want to know, believe me. I've broken several myself over the years!
If the bike offers it, it's ok to get the standard hub that breaks with their right leg as well, and handbrakes, double the stopping power! Also, out in Mesa, Arizona, I can't count all the times I've fishtailed with my BMX bike with that feature! You may not get that on some of the higher end bikes, but on many you still will! Ask for both if they have it, the coaster brake style with handbrakes!
Invest in a mid-range helmet, that is ANSI Certified and is labeled by them. Get gloves that are of excellent quality as well. Every BMX bike should have goosekneck, handlebar, and top frame pads, bare minimum, do not let your child take the bike without them.
Frames that are welded should have beautiful thick welds that you'd want to eat off them. Don't buy any bike with ugly looking welds. Also, watch out for over priced bikes that have beautiful welds but low componentry.
I always like to buy my BMX bikes with similar equipment too! If hubs, cranks, brakes, and so forth are all Shimano, that's a good thing. The bike is Shimano equipped. I'd steer clear of BMX bikes that have lightweight handlebars, but heavy cranks, hubs, and are made by 10 different companies!
In conclusion, there are only a few key things to remember. Weight. Get the lowest weight rims, hubs, and components that are of the highest quality. It is ok to have a heavier frame, but don't compromise on wheels, tires, or most of all-brakes! Buy a Haro, Diamond-Back, Red-Line, or Mongoose from a Bike Dealer, and your going to be happy! Don't buy from the local chain stores anymore, ever! Buy direct from your local bike shop that knows BMX!
Lastly, have fun, and jump! If you can't jump the bike, don't buy it. The frames should be cleared for jumping! And remember, most of all, your BMX bike will be a part of your son or daughter's life for at least 5-7 years, so go ahead, spend a couple hundred more for better components. And remember, to hit a ramp, fly up, hold the bars, kick the rear wheel out, and just hang on, feeling nothing but the air and rising above the earth, on a BMX Bike, is something your child will never ever forget and will pass on from generation to generation.

Tennis Shoes



Good tennis shoes do several things apart from covering your feet, and tennis is a sport, that is very hard on shoes, and feet, so you need to find a shoe that will last, and one that is not too heavy, bearing in mind some factors.
Tennis shoes must be able to support your feet with all the stops and starts you have to make, and it must give you good support at the sides of your feet. Each surface has differing requirements, and all of us have different types of feet, all of which places different demands on your tennis shoes.
The first consideration is what type of feet you have, because that will determine how much cushioning you will need, and what and where you will need lateral support.

There are three basic foot types:
1. SUPINATED – here your wear is on the outside of the shoes
2. PRONATED – here your wear is on the inside around the ball of the foot, and this type of foot suffers the most with injuries from overuse.
3. IDEAL – here the wear is even.
Either get a fellow player to walk behind you to determine whether you are walking with your foot tilting inwards, or outwards, or not at all. Better still find yourself a well-qualified sports shoe person. You could also test yourself by wetting your feet and standing on a square of cardboard.
1. If there is a large are where the arch of your feet didn’t touch you are SUPINATED
2. If the whole of your foot is marked, looking like a rectangle with slight curves then you are OVERPRONATED
3. If your feet leaves an imprint that is a balance between the others then your foot is IDEAL
Confirm this self-diagnosis with a third party watching you walk, and the wear test on your current shoes.

THE FIT OF THE TENNIS SHOE is vital, and points to pay particular attention to are as follows.
1. You need about half an inch of space between your longest toe and the end of the tennis shoe.
2. The foot should be a comfortable fit without any stretching3. The heel should not slip, although some movement is wanted.

Just remember your feet are different sizes, so pick your size according to the larger foot, and use an insole to balance up your smaller foot. The most important thing in a tennis shoe is LATERAL SUPPORT because much of your running on a court is side to side, and there are dangers of turning your ankle. Good lateral support is necessary if you are heavy and if you are pronated.
Your tennis shoes will need a degree of CUSHIONING and SHOCK ABSORPTION. This is especially true if you are a baseliner, and you play most of your tennis on hard courts. Pronated feet jar most easily.
The two most common cushioning you read about are EVA, which is lightweight, but not very durable, or stable, and PU[polyurethane] which is denser, better stability, but it is a lot heavier.
FLEXIBILITY is important, and tennis shoes must bend easily at the ball of the foot, however too much flexibility makes for a shoe that won’t be comfortable.
At the end of the day, comfort is important, and tennis shoes are no different to anything else, you tend to get what you pay for, and I know very few things of quality that are cheap!!

Tennis Skirts


If you are not that keen on wearing the ubiquitous mini skirt that is being forecasted as a sure-fire fashion staple for Spring 2006, summon up your inner athlete and go with a short, pleated tennis-inspired skirt made of comfortable, wearable sweatshirt fabric instead. This fashion-forward key constituent of the preppy trend will make you look sporty chic when a casual look is in the cards.
The 'tennis whites' look, however, is passé. The flirty, pleated white skirt may be considered a classic in the strictest tennis circles but you could alternatively add a little punch to your sporty wardrobe by going in for some interesting fashion variations. Tennis skirts are now available in a variety of sporty colors, silhouettes and cuts, and look fabulous in soft and vibrant hues like peach, aqua, olive green and ruby red.
This is a very informal sporty style, so it is best to pair tennis-inspired skirts with preppy items like the classic polo shirt or a tennis tee. Fashion critics advise not to pair it with sneakers off the court. These little skirts look great when worn with strappy wedges, Speedo sandals or even round-toed pumps.
Although fashionistas and others in the know often declare that for pleated and multi-layered skirts, the shorter the better, it is advisable to keep the length at mid-thigh and team tennis skirts with a modest sports t-shirt if you intend to wear it for a serious game of tennis. Indian player Sania Mirza was recently in the eye of a storm due to her midriff-baring tennis attire. India's Sunni Ulema Board, a Muslim organization, issued an edict in October 2005 demanding Sania to cover up during her tennis matches, and described her tennis clothes as "un-Islamic."

Tennis Game

No matter what level of tennis you play, you always want to get better. Even Roger Federer and Rafael Nadal, the two top men's tennis players in the world, seek to improve their games. Since both can well afford to pay coaches with far greater expertise than this humble writer, the following suggestions are geared toward the amateur tennis enthusiast.
The best goal to set for yourself, and the hardest to attain, is improving your footwork. This can be as simple as taking your heels off the court when you're at the net or receiving serve. Doing so will give you an extra split second to move for your shot. There are also numerous drills that you can incorporate into your practice routine, like running up to the net and back, or gliding rapidly along the baseline. Running backwards improves balance and well as foot speed. Jumping rope is a good exercise to improve your fleetness of foot, too.
If the majority of your tennis is played socially, and you've reached one of those plateaus that abound along the journey of tennis, another aspect of your game that you can re-emphasize is watching the ball. Although that is the first lesson any teaching pro emphasizes, it's also the first one that is forgotten by most players. Everyone has a tendency to watch where his/her shot is going to go instead of concentrating on the act of hitting it. Focusing on your performance can be difficult when you're playing with your usual foursome, but if your goal is to improve, a deliberate effort to separate chatting at the net and bantering between points from actually playing the game needs to be made. It takes practice and determination to do this, and it's about as much fun as watching paint dry, but when mastered, you'll see a significant change for the better in your game. One boring way to do this is stare at the tennis ball you're squeezing in your racquet hand while building up the strength in your hand and forearm.
Finally, something that you can do on your own to improve your game is to get into better shape. If you can run faster or longer than you have previously, your tennis game is bound to become better as a result. Wind sprints, when you run fiercely for a few yards and then pause only to start to run again, are a good imitation of the type of action found in a competitive tennis match. Bicycling will strengthen your leg muscles, too, and if it can save you some gas money as well, all the power to you.
If you've played tennis for any length of time, you know that improvements rarely, if ever, happen overnight. However, once you've chosen to improve, mapped out a program and followed it through, you also need to keep believing in it. Sometimes you need to take a step backward before you can go two steps forward, and this can often be the case when you change your tennis game.

Tennis Rackets




With the current range of tennis rackets available, it is often difficult to make the right decision when buying one. This article will explain some of the technical terms involved with the tennis rackets to help the reader pick one that is suited to them. After all, with modern rackets costing 200 dollars or more, it is very important to make the right decision. Simply put, the easiest way of determining whether a racket is for you is by trying it out. Most tennis stores offer demo rackets, and make sure that you try out a range.

The problem arises when one decides on this range' of rackets, as selecting them from such a large number of rackets is difficult. Here are some technical terms explained.

1) Headsize Go with the headsize that suits your game. Current tennis rackets headsizes range from 90 to 125 square inches. In theory the larger the headsize, the greater the power with reduced control, while the smaller the headsize, the greater the control and the lesser the power. Generally players with single handed backhands and with a strong net component to their game will benefit from a smaller headsize, while players who hit double handed backhands and play from the back of the court may well find larger headsizes suit the game better.

2) Balance The balance of a racket is very important. Tennis rackets that hold more mass in their head than the handle, will provide additional power, while reducing control. A racquet with more mass in the handle will enhance maneuverability and precision while decreasing the power one can generate.

3) Stiffness - a stiffer racket will increase the power of the frame, but will be harder on your arm, while a more flexible racquet will have less feel, but be more comfortable.

4) Weight The weight of the rackets determines how fast your arm becomes fatigued when playing with it. A greater weight, while more taxing to carry around, will result in less overall vibration when striking the ball.

In short if it is comfortable and you feel good playing and winning with it, use it! Ignore the labels and marketing and play with the racket that best suits your game and gives you the highest level of comfort.

Tennis Elbow


Tennis elbow, or lateral epicondylitis, is the most common injury in patients seeking medical attention for elbow pain. Exactly what causes tennis elbow is unknown, but it is thought to be due to small tears of the tendons that attach forearm muscles to the arm bone at the elbow joint.

The muscle group involved, the wrist extensors, function to cock the wrist back. Specifically, the extensor carpi radialis brevis has been implicated in causing the symptoms of tennis elbow.
What are the symptoms of tennis elbow?Patients with tennis elbow syndrome experience pain on the outside of the elbow that is worsened by grasping objects and cocking back the wrist. The most common symptoms of tennis elbow are :

-Pain over the outside of the elbow

-Pain when lifting objects

-Pain radiating down the forearm

The pain associated with tennis elbow usually has a gradual onset, but it may also come on suddenly. Most patients with tennis elbow are between the ages of 35 and 65 years old, and it affects about an equal number of men and women. Tennis elbow occurs in the dominant arm in about 75 percent of patients. Anyone can be affected, but tennis elbow is most commonly seen in two groups of people:

Manual Laborers. People who work with their hands are at greater risk of developing tennis elbow. Jobs that may lead to tennis elbow include plumbers, painters, gardeners, and carpenters.


Sports Participants. Sports participants, especially racquet sport players, are prone to developing tennis elbow. About a third of regular tennis players experience tennis elbow at some point in their careers. In addition to racquet sports, tennis elbow is seen in golfers, fencers, and other sports participants.


Are special tests needed to diagnose tennis elbow? X-rays of patients who have the diagnosis of tennis elbow are almost always normal. Other tests, such as an EMG, are sometimes conducted if there is confusion about the diagnosis.
Other causes of pain over the outside of the elbow include instability of the joint, elbow arthritis, and radial tunnel syndrome. The symptoms of these conditions are usually distinct, but in some cases they can be confusing.


What is the problem occurring in tennis elbow?
No one knows for certain, but there are several ideas. It is known that tennis elbow is not simply an "inflammation" of the tendons around the joint. The problem is thought to be more of a degenerative process as a result of aging or repetitive use. The symptoms may be the result of an incomplete healing response in an area that does not have good blood flow and therefore has difficulty accessing nutrition and oxygen necessary for healing. This leads to degeneration of the tendon causing small tears.

When do I need to see the doctor for tennis elbow? Bring the following symptoms to your doctor's attention:

-Inability to carry objects or use your arm
-Elbow pain that occurs at night or while resting
-Elbow pain that persists beyond a few days
-Inability to straighten or flex your arm
-Swelling or significant bruising around the joint or arm
-Any other unusual symptoms
