Have you ever seen or used a chainsaw previously? This is a mechanical saw, using the power of electricity, compressed air or hydraulic to operate. The modern chainsaws use the power of a two-stroke engine to run. This device has many uses including, briefly the following:
• Cutting down the trees
• Tree pruning
• Tree bucking
• Cutting branches and
• Cutting firewood, among others
The chainsaw tool has existed for years. It has a long history in which the tool boasts amazing changes in style, features and even the functioning mechanism. Even so, it is hard to tell exactly when the first tool came up. This issue is contentious. Some people argue that the first chain saw emerged at around 1830. To support their fact, they quote Bernard Heine (German orthopaedist) as the man behind this early tool's innovation.
They continue to describe the tool (osteotome), saying that it had some chain links supporting tiny cutting teeth, set at a given angle. During the bone cutting process, the chain could spin around a channeling blade. This would in turn, move the sprocket's wheel handle. The other group of people believes that the chain saw hand tool emerged for the first time in 1920's. They go on to call this tool the true chain saw mainly used in forestry work.
The men behind the 1926 and the 1927 inventions were Joseph Buford Cox and Adreas Stilhl respectively. Stilhl specifically made an electro chain saw in 1926. Another inventor, Emil Lerp, the founding father of Dolmar Company, in 1927, came up with the first ever tool to use gasoline or petrol, as the main power source. Dolmar Company even went a step further to produce the new chain saw in masses. Thus, one could say that only the petrol or gasoline driven chainsaw tool invention emerged in 1920's. These tools:
• Made tree felling process at large, easier than before
• Were heavy or bulky hence, not very portable
• Could break easily
• Could consume huge amounts of energy
• Featured two-men operation
Because of these difficulties, new inventors had to eliminate the problem of bulkiness in particular. They sought to create a portable chain saw tool for one man. This achievement materialized in 1950, even though the tool was rather bulky. Nine years later, another invention for a tool weighing roughly, twelve kilograms, came up. Compared to the modern chain saws, this equipment was still heavy. On average, the modern tools for smaller tasks have an approximate weight of four to five kilograms.
The commercial use modern chain saws weigh about seven and nine kilograms. Overall, the shoppers in those days enjoyed the new one-man tool. The two 1950' one-man chain saws were efficient and reliable for forest tasks. Even though, the tools did not exactly impress some critics. This did not stop the alteration of this useful tool in the sixties, when the antivibration system released. In 1972, another sharp brain invented the chain brake, improved and replaced in 1982, by the quick stop, an automatic chain brake. By 1989, someone had released the catalyser, and two years later, the chainsaws featured an automatic start.

Know You're Safe After Installing Performance Brakes
The disc brakes found on most modern vehicles today are a two-part brake system made up of a disc or rotor and a brake caliper assembly. The caliper assembly contains hydraulic pistons that push against the back of the brake pads, clamping them together around the spinning rotor to slow down the vehicle. The harder they clamp together, the more friction is generated, which in turn produces a higher level of heat. While this transfer of energy is necessary for the braking process, there is also a tipping point. When brakes become too hot, they quickly lose their effectiveness.
Often the result of extended or performance driving conditions, brake failure can be catastrophic. That's why the pros use performance brake components to ensure safety and stability. And, that practice has rapidly has made its way into the consumer market with vehicle owners upgrading their cars and trucks with a number of high-performing aftermarket parts.
One of the most effective upgrades to your brake system is the addition of performance brake pads, and ceramic brake pads make ideal replacements. They're forged from copper and result in less wear than their steel counterparts while providing a more effective heat transfer. In addition, performance brake pads cool faster, last longer and are virtually silent, generating a level of sound outside the range of human hearing. Plus, the dust created by a ceramic brake pad is light in color, keeping those chrome wheels polished to a high sheen and free of the black chalky discoloration produced by standard brake lining.
The second most important upgrade in relation to performance brake kits is a stronger set of rotors. Heat is the number one corruptor of brake performance. Also known as "brake fade," the pedal becomes soft or non-responsive after driving long distances or braking down a steep decline. Performance rotors are slotted, like those found on a racecar. This design allows for a more rapid cooling of the braking surface, which translates to increased performance and added bite. Plus, in wet weather, performance rotors channel water away from the braking surface by allowing it to pass more freely through the holes, adding significantly to overall performance by preventing the loss of braking power that accompanies waterlogged brakes. In addition to performance, slotted rotors are cross-drilled and fill more of the space behind the wheel to provide a tougher, race-ready look.
Another major component when it comes to brake accessories is a solid set of brake lines. Next to brake pads and rotors, brake lines are a major contributor when it comes to slowing your vehicle. Unlike the other two components, brake lines are somewhat exposed and easily damaged or punctured by rocks, sticks and other debris. When they become damaged, brake lines fail to deliver the proper amount of hydraulic fluid into the brake system, causing a lessened (and sometimes complete lack of) response. Unlike those flimsy rubber stock hoses, performance brake lines are crafted to last and come in stainless steel, resisting corrosion and abrasion while enhancing pedal-feel and greatly improving upon the performance of your stock parts.

Please help me choose a good trials bike?
I'm looking for a trials bike right now.
I know what parts I'm going to use, but I'm not sure what trials frame I want to choose.
I'm considering three frames.
Adamant A1 26inch
Gu's 26inch
and Czar's 26inch
And please note that I also care about its prices.
Also I want to know how hydraulic v brakes work.
I see a lot of people using them for their rear, but are they really as nice as disk brakes to work with??
cuz I'm thinking a dual 7inch hydraulic disk brake setting for maximum braking power. But the disk brakes add a lot of weight.......
What kind of brake set up do you recommend for bike trials??
I'd go for the Czar first, then the Adamant, and the Gu. They're all good, but Czar makes great stuff. I have a friend who got the A1 and has had some problems with it....the rear triangle was misaligned and he got a replacement frame under warranty after having gone through a couple freewheels and having some brake alignment issues with his HS-33s. It's a sweet looking bike, though!
V-brakes, hydro rim brakes, or discs are up to you. Most people seem to run the HS-33 rim brake on the rear, with that or a disc on the front.....but there are all kinds of setups out there. If you go disc, you'll want 8" in the rear unless you're just doing smaller street riding....for nats and large drops, you want the most brake in the rear as you can get....and also get the best halflink chain you can find, for safety's sake.
The rim brakes are fine...use a good pad like Moe's and consider having them do a rim grind for you. They tend to be noisy...but that gets to be like music to your ears after awhile. Discs are quieter, but you run the risk of bashing up your rotor if you do side hop ups or get sloppy....rim brakes are out of the way. Also, some disc brakes are kinda sloppy where the pads fit in the caliper, and it seems to vary even among the same model from the same manufacturer. The Hope mini trials brake gets great reviews.....mixed reviews on other brakes, though. A lot of people never really get them burned in, however, and that has a LOT to do with how well your discs will grab.
Don't worry about weight of the brakes....use what works for what you want to do. You're only talking a couple ounces anyway. Most of the weight of your bike will be in the frame, wheels, and tires.....the other parts are chicken scratch in the overall picture.
Since you're building up a new bike, consider doing a front freewheel setup.....they seem to be more durable. Plus, it looks totally cool while the chain is moving and your feet aren't.
