Liquid Bearings 100%-synthetic Oil for Specialized Bicycles, Provides Superior Lubrication and Also Prevents Rust!! Sale Price: $6.99  |
|
This is the synthetic lubricant that consistently outperforms all others currently available. It has incredible low and high-temperature characteristics, which is absolutely necessary for proper bicycle lubrication but completely lacking in petroleum-based oils. Don't use them on your bicycles any longer! Actual oils and lubricant sprays leave sticky deposits when they evaporate over time. Real oil is made up of a mixture of long and short chains of carbon and hydrogen atoms, and under certain conditions the short-chain molecules evaporate, and the unstable molecules oxidize and break down. This leaves a sticky residue which can actually "gum up" the device it was intending to lubricate. Conventional oils also contain impurities such as sulfur, waxes, and unstable hydrocarbons which are left behind as residue deposits. In contrast, synthetic oils are made using a process that re-arranges the structure so all the molecules are uniform in size, shape, and weight, an ideal phenomenon which does not occur in nature. Synthetics are custom-designed to produce the ultimate lubricant, with inherent performance characteristics vastly superior to any petro-oil. Liquid Bearings is also essentially odorless, so your hands and clothes won't smell like oil after using it. It is perfectly safe to begin using Liquid Bearings on all your bicycles immediately, even if you have been lubricating them with conventional oils for years or decades. It is fully compatible with all vintage and current oils, and will eventually flush away the residue of the evaporated real oil over time. You will easily notice that all of your cables, derailleur, slides, bushings, bearings, chain, and gears will move easier with Liquid Bearings, especially if you have been using petroleum-based oil on them for years. It is completely plastic-safe, and will not harm painted surfaces. The bottle is top-quality LDPE, and the stainless needle allows the application drop-by-drop. |

Liquid Bearings synthetic oil for Bicycles, Provides Superior Lubrication, Also Inhibits Corrosion Sale Price: $6.99 |

This is the synthetic lubricant that consistently outperforms all others currently available. It has incredible low and high-temperature characteristics, which is absolutely necessary for proper bicyclelubrication but completely lacking in petroleum-based oils. Don't use them on your bicycles any longer! Actual oils and lubricant sprays leave sticky deposits when they evaporate over time. Real oil is made up of a mixture of long and short chains of carbon and hydrogen atoms, and under certain conditions the short-chain molecules evaporate, and the unstable molecules oxidize and break down.

Synthetics are custom-designed to produce the ultimate lubricant, with inherent performance characteristics vastly superior to any petro-oil. This fully synthetic proprietary blend is suitable for all bicycle applications, including friction points of mating or sliding parts, levers, derailleurs, cables, pedals, chain, and general corrosion prevention. It does not contain any graphite or Teflon components, it will not attract or retain dirt and contaminants like petroleum-based oils do, and will never harm or soften any plastic or rubber components or painted surfaces. It is the absolute best for "wetting" your chain, and it doesn't subsequently evaporate and let it corrode. Regular oil starts out "wet", but evaporates as time passes, and eventually your chain will begin to rust. Liquid Bearings stays "wet" essentially forever, because it never evaporates! It is simply the best at preventing rust. |
Featured Article:
A diagnosis of osteoarthritis of the hip generally progresses to the likelihood of requiring a hip replacement in the near future. As the degenerative condition advances, it causes a decreased range of motion, pain, muscle weakness, gait changes, and tight muscles. Specific exercises designed for hip arthritis can help maintain range of motion at your joint, prevent loss of muscle, stretch muscles that will become tight, and lubricate the joint to decrease stiffness and pain. In addition, performing exercises prior to surgery will speed up your recovery post operation.
Goals of a Hip Arthritis Exercise Program - Pre Operation:
There are two main goals to target with a pre operation hip arthritis exercise program. One is strength of the gluteal muscles and the other is to maintain range of motion by working within your pain free range. There are exercises that work both of these goals simultaneously. The gluteal muscles are extremely important to strengthen pre operation because they comprise the stability of the joint. Ironically, arthritis causes pain, decreased range of motion, and therefore less weight bearing which all contribute to atrophy, or shrinking, of the gluteal muscles. Therefore, it is paramount to actively engage in specific strength exercises that target these muscles. Although strength and range of motion are highlighted as the priorities here, cardiovascular or aerobic conditioning is also extremely important. Usually due to pain and decreased range of motion, both walking and overall activity are reduced drastically which negatively lowers an individual's aerobic capacity. Using stationary bikes or participating in water classes are excellent non weight bearing options to keep your cardiovascular conditioning strong.
Hip Exercises Post Surgery
There are a series of exercises your physiotherapist will guide you through immediately post operation. They will guide you through an exercise program that will be safe with the goal of returning you to full function in daily activities. This program will last up to 6 to 8 weeks post operation. A lot of patients stop the exercises once they are discharged or released from the supervision of their physiotherapy. It is imperative that you continue hip strengthening exercises in a progressive format for at least one year post operation. Patients that have continued with an exercise program consistently for a full year post operation, receive amazing results in functional ability.
Goals of Hip Arthritis Exercise Program - Post Operation:
Follow the exercise program guidelines given to you by your physiotherapist for the first 6 to 8 weeks post operation. The post operation exercise program varies from the pre operation program on three aspects which include the following: range of motion stretches have to be modified to follow restrictions that protect your joint from dislocation, strength exercises will progress to weight bearing, and one leg balance exercises along with gait retraining become a priority. Post surgery, the goal of your exercise program should be to progressively advance your strength exercises, when your body is ready, from isolated muscular endurance exercises to dynamic, functional exercises. Again, the most important muscles to strengthen post operation are your gluteals. Your exercise program should also include quadricep strengthening and core stability exercises. When you are selecting exercises, it is highly advised to select unilateral or one limb exercises in order to make the strength equal across limbs.
The journey your muscles have endured from the pre surgery pain through the operation leaves them tight and contracted in a shortened position. Therefore, stretching is equally important to include in your post operation exercise program. Often the hip flexors, hamstrings, and quadriceps will be tight post operation and need to be stretched. The very exciting aspect of the post operation exercise program is that you are pain free and therefore can gradually increase your cardiovascular training time and intensity to your pre arthritic conditioned level.
When you are disciplined at consistently keeping up with your exercises and gradually progress through incremental stages of exercises, you will notice huge improvements in your cardiovascular, strength, flexibility, balance, gait, and overall functional ability. The importance of engaging in a regular, consistent exercise program both pre and post hip operation will impact your full recovery greatly. A hip exercise program is the best single action you can take to encourage a highly successful return to function post surgery.
Jody Kennett has specialized working with Joint Replacement clients pre and post hip replacement surgery for over a decade. She has a background in Kinesiology and is an A.C.E. Advanced Exercise Specialist. She gained knowledge and expertise with joint replacement exercises by leading and building a Joint Replacement Exercise Program that ran 6 classes of 12 participants. As she saw the incredible benefits her participants gained through exercise and realizing how specialized this program was, she created an instructor training manual and course. Most recently, she has created detailed eBoks on exercises for both hip and knee replacement designed to educate the patient.

History Of The Bicycle At A Glance
Unlike other inventions like electricity and light bulb, the origin of bicycle has never been very clear on who invented it. Depending on the nationality of who you ask you could get an American if you asked an American, a Scotsman or a Frenchman if you asked people of those nationalities. The bicycle went through centuries of innovation and improvement before arriving at what we have today.
The first authentic bicycle was made in the year 1817 by Karl Drais von Sauerbronn to facilitate transportation during an acute shortage of horses for carriages. However, this device did not have any pedals and had to be moved by pushing one's feet against the ground. The question remains whether a bicycle without a pedal can be called a bicycle or not.
The next improvement took place in 1863 with the invention of the bone shaker or the Velocipede. The importance of this improvement can be understood from the fact that a museum dedicated to this innovation exists even today. The discomfort involved in riding this device over cobblestones prevented it from becoming more popular.
The year 1870 saw the bicycle become a lot more comfortable with the use of a big front wheel and solid rubber tires. However, even the slightest jerk would send the rider crashing to the ground. This proved to be a major impediment in the spread of bicycles.
As technology improved, bicycle manufacturing became more specialized. Ball bearings, caliper brakes, speed gears- all made their introduction as the first American manufacturer of cycles came into existence in 1878.
Safety improved and people began lobbying for better roads to make bicycle driving more comfortable. In the meantime, the rear wheel driven bicycle, as we know it today, was designed and proclaimed to be a lot safer. It was named the Bicyclette and was a French innovation.
The 1880's saw better and better bicycles being made. The 1890's was called a gay decade and the bicycle is credited for making quick transportation a reality. In 1896, Susan B. Anthony said that "the bicycle has done more for the emancipation of women than anything else in the world."
However, the idea of not using a solid piece of rubber as the tire did not come about until, a young doctor named Dunlop came up with the bright idea of using air filled rubber tube to make the bicycle faster and more comfortable. A new era was born with bicycles being used by adults and kids alike. Bicycle clubs were formed and bicycle racing became a sport.
World War I and World War II saw the growing importance of the bicycle. Of course, the automobile industry attracted all the attention and many feared that the bicycle may become a thing of the past. However, the bicycle has retained its charm and utility even today and has diversified and grown into a huge industry.
