Remember, if you do not think the motion on the change? His bike had a gear connected to the bicycle pedals and a small sprocket with the rear wheel that is all you need. So you get a bit 'older people and the first 10 days. The bike had two front teeth and five on the back. In all likelihood, the two levers lever on the bicycle frame near the handlebars. Over time, the shift lever is moved to theArm and then was selected in the advanced search to the right of the handle. And next thing you knew, instead of a mere ten-speed on your bike you were riding a 27 speed mountain climbing machine!
Why this tool? Faster and easier to drive, of course. Regardless of how many gears your bike has, he has 2 or more then there is a basic set-up, which employs almost any bike.
First, you have your front and rear sprocket. This,together with the chain are the key components of the gears. To find out what gear ratio comparing the number of teeth on the pinion on the number of teeth on the pinion.
If your gear has 52 teeth, and your crown has 20 teeth, then you're looking at a ratio of 2.6. The higher the ratio, the faster the transition. In general, the change on the front, starting from the inside, growth as we move out. At the rear, however, is the largest marchusually the inner and smaller and smaller as you move out.
The next important component for your bike gear bike, the shifter, front derailleur o. The change is what moves the bicycle chain from gear to gear. A typical navigation system uses both a front and rear derailleur. Without the switching mechanism would not be able to shift gears. The circuit is composed of chain rollers and cage, and the part that is actually in contact with the chain. Roles areThe shift cable attached. There are separate cables for the front and rear derailleur. The transmission cable connected to the gear lever.
There are a number of gear-shifter now available, covering a wide price range. The gear lever is what you can change gears. The first type of gear shift levers were known as friction. This worked just pulling the wires for the front derailleur.
Controls friction can be disturbing, because the way they were designed forcan easily get caught in the gears and gear accidentally damaged or even destroyed. The variety most advanced exchange is known as a change of index.
Index shifters stops are specific and are calibrated to the perfect gear gear. They eliminate the disadvantages of the old friction shift. shifter can be placed anywhere in the frame to the handlebar base for the handles of models that seem to be a part of the brake lever.
The bike ridersseveral drafts to make it easier for you to negotiate difficult terrain. The higher gears are there to help you speed downhill or flats and lower gears are there to help you get through these difficult climbs. Remember, it is best to change gear if you do not put a lot of effort on the pedals. Shifting, if too much pressure on the pedals can damage the navigation system.
