A Look at Some of the Mountain Bike Parts Available
One may have never thought about the parts that are required to make a mountain bike while riding it. But sometimes it becomes important to know the parts. You never know where they will help you. Some of the mountain bike parts are:
The Bottom bracket which is an attachment of the crank set to body of the bike. It can be replaced or adjusted.
The Brake cable: it is a cable that is used to attach the brake lever to the mechanism.
Brake lever: It is a handlebar lever used for activation of the brakes. The brake on th left side is for the front and the one on the right is the rear brake.
The bike consists of a chain circular set of links which transfers the power from the chain ring to moving parts of the wheel.
Chain ring: these are toothed rings which are attached to the crank that holds the chain and are important mountain bike parts.
Crank Lever: it extends from the bottom bracket to the pedal of the bike and transfers the power to the chain rings and is one of the mountain bike parts.
Derailleur Mechanism is required for moving the chain from one part to another.
The down tube Section of frame extends downward from the stem to the bottom of the bracket.
Dropout cut slots are provided at the bottom of front fork. They are designed to allow the axle of the wheel.
Front Shock absorbers are provided on the front fork.
Handlebar: a horizontal bar is fixed to the stems which have hand grips at its end and the brake levers and shifters are attached to it.
Headset Mechanism is in the front of frame which connects the front fork to the stem and also the handlebars.
The spokes are attached to the Hub Center section of the wheel.
The end of the spoke in the rim is held by a nipple threaded receptacle.
Rear Shock absorbers are provided on the rear tire in most of the dual-suspension bikes which is another of the important mountain bike parts.
Rim: it is a metal ring with a U-shaped cross section which connects the spokes to the tire which is on the outside.
A Saddle Seat is the part one should not sit on when riding steep downhill.
A Seat post supports the post for the saddle. It is mounted into the seat tube with a mechanism for changing its height.
Skewer Metal rod: it goes all the way through the core or the hub.
The crank arms are attached to a spindle freely rotating axle. It is a part of the bottom bracket.
There are thick wires which join the hub to the rim. The tension in it is adjusted by means of a nipple available on the rim side.
Tire: they are on the outer part of the rim. They make contact with the road while riding and also provide a grip.
The Top tube is present in the top bar of the bicycle frame.
The spikes are attaches to the wheel hub Center of the wheel.

G&G Armament – A Quick Overview of Airsoft Guns by G&G Armament
Whenever you are out in the field in the middle of an airsoft exercise, it always pays to make sure that you have a piece of equipment that is going to deliver for you consistently. Whenever you choose something from the G&G Armament, you are sure to receive everything that you’re going to need. Here is a little bit about the G&G Armament of weaponry that you will find available from this company. Regardless of which of the guns you happen to choose, however, you’re sure to get quality and performance from g&g airsoft guns.
Who Are They
G&G has been in business for over 20 years, manufacturing airsoft guns and other equipment that makes them one of the industry leaders. They are focused on quality, both in the equipment that they deliver and for the quality of the customer service that they give to individuals who purchase from the G&G Armament. This makes it a clear choice, but there are are some specific guns that are available which we find to be some of the best that can be found.
Some Popular Guns They Make
For example, the G&G G96 Airsoft green gas/propane powered Sniper Rifle is a solid piece of equipment, that is a bit on the heavy side but most people tend to appreciate that in order to get a little bit more accuracy. The clip is capable of holding 15 rounds and fires them over 600 FPS, which is enough to lay down some serious cover fire for your teammates. As with most of the guns in the G&G armament, it is a combination of metal and ABS plastic. It’s an excellent choice for anybody that is going to be an air soft sniper, but keep in mind that it does not come with the gas. Gas is available optionally from your retailer, so make sure that you order yours at the same time as you order the G96.
They Even Make Great Guns For Beginners
Another good choice for use on the skirmish field is the G&G Combat Machine Series. These are excellent beginner guns from G&G and provide high rates of fire and velocities over 350 FPS and prices under $200. The combat machine series gives you the option of semi automatic and full automatic fire, along with some other included options which make it an excellent choice for beginner and intermediate airsofters ready to do battle.
Beginner Triathlete – Novice Ironman and the Importance of Wetsuits – Warmer, Lighter Or Faster?
It is pretty obvious to the triathlon community that triathlon wetsuits are not all created equal.
At the same time, it often feels like we have taken the importance of exactly how a triathlon wetsuit is actually constructed a bit too seriously. After all, when it comes right down to it, is really necessary to get excited about a wetsuit because it is a millimeter thicker than the one you owned the previous season?
It appears that the goal is to have a creation that is thinner and faster, but still as warm as a wetsuit with thicker construction.
IN THE EARLY DAYS
In the early days of triathlon the races were few and far between. To make matters worse, in many areas with water temperatures that hovered around 60 degrees Fahrenheit it was a challenge for many triathletes just to avoid hypothermia. There simply were no wetsuits back then except perhaps for the early “Farmer John” type that did nothing at all to keep a person warmer, which begs the question, “what exactly did they do”?
Of course a person could always buy a “dry-suit” –that would be impossibly heavy and hot– at a dive shop, but it would be years before the real triathlon “wetsuits” were available to all triathletes regardless of where they lived.
For the Canadian triathlete, it was pretty much almost a certainty that hypothermia was going to rear its head in any triathlon swim leg in Canada back in the eighties unless the race happened to be on the West Coast. The severity of the hypothermia often depended on actual swimming ability of the triathlete. The better a triathlete could swim back then, the sooner the swim leg would be over so it was a simple matter of those whoever got out of the water the soonest were less likely to suffer from the cold as much.
EFFICIENT SWIMMING IS THE KEY
If a triathlete did not have an energy-saving stroke it was often difficult to retain enough co-ordination once out of the water to be able to climb on a bike. It was not unusual for it to take ten minutes or more for a triathlete to warm up enough to be able to cycle at all. Some of the early triathletes reached the danger point of hypothermia and were often unable to carry on in the race at all.
The wetsuit was born in the mid to late eighties and began to evolve at a quick pace in the decades to follow. Every single year you could pretty much be guaranteed that a new improved wetsuit would be on the market. Often the new wetsuits came with the promise that it would make you a faster swimmer then ever before.
FASTER IS NOT ALWAYS BETTER
This philosophy of “faster is better” really sucked people in because they had yet to figure out how little importance swim time really has on the end result of an Ironman. This is especially true of age-groupers who simply want to finish the race any way they can. Still, many triathletes were sucked in over and over again and could spend a few thousand dollars on wetsuits over a career.
Unfortunately, it would take years for some triathletes to figure out that swimming faster is not the secret to a successful Ironman. Real success is realized when emphasis is placed on finishing the swim leg of an Ironman with as little energy loss as possible. In reality, success in an Ironman has very little to do with the thickness of a wetsuit, how seamless the stitching, or how stretchy the armpits are.
STAYING WARM IS THE KEY
Ultimately, the most important feature of a wetsuit for the average age-group triathlete or novice Ironman is the protection it provides from the cold. It is of paramount importance to always keep in mind that if you burn yourself out from the swim because you lack a smooth, energy-saving stroke you will most likely be part of the Ironman “death march”.
For the beginner triathlete or novice Ironman, the goal should be to get through the swim with as little discomfort as possible and with as little mental, emotional, and physical stress as possible. Any type of stress has a way of contributing to the loss energy that will without a doubt be desperately need later on in the race. This is most especially true to the Ironman because of the sheer distance of the race.
