The gears in mountain bikes just keep getting more and more intricate. The bikes of today have as many as 27 gear ratios. A mountain bike will use a combination of three different sized sprockets in front and nine in the back to produce gear ratios.

The idea behind all these gears is to allow the rider to crank the pedals at a constant pace no matter what kind of slope the bike is on. You can understand this better by picturing a bike with just a single gear. Each time you rotate the pedals one turn, the rear wheel would rotate one turn as well (1:1 gear ratio).

If the rear wheel is 26 inches in diameter, then with 1:1 gearing, one full twist on the pedals would result in the wheel covering 81.6 inches of ground. If you are pedaling at a speed of 50 RPM, this means that the bike can cover over 340 feet of ground per minute. This is only 3.8 MPH, which is the equivalence of walking speed. This is ideal for climbing a steep hill, although bad for ground or going downhill.

To go faster you’ll need a different ratio. To ride downhill at 25 MPH with a 50 RPM cadence at the pedals, you’ll need a 5.6:1 gear ratio. A bike with a lot of gears will give you a large number of increments between a 1:1 gear ratio and a 6.5:1 gear ratio so that you can always pedal at 50 RPM, no matter how fast you are actually going.

On a normal 27 speed mountain bike, six of the gear ratios are so close to each other that you can’t notice any difference between them.   Read more...

The most important thing for any business to succeed is advertising. Therefore business owners and entrepreneurs constantly lookout for legitimate and profitable advertising venues. Paid to surf or auto surf programs are particular type of online advertising where members sign up with programs that display advertisements in their browser. The person is paid for each site viewed.

A pay-to-surf company would provide a “view bar” to be installed on a member’s computer. This view bar tracks web sites that the user visited, advertiser pays the pay-to-surf companies a small amount for every hour of a member’s surfing.

Of all the venues the newest and fastest growing venue is auto surf programs. These auto surf programs are traffic exchanges that automatically rotate advertised websites in a person’s Internet browser. They bring a huge amount of traffic to an advertised website.

In this program the timer keeps track of how many websites have been visited by the person and pay accordingly. And this payment relatively varies to the amount invested. That is if the membership level is 12 dollars and the money paid is 2 percent a day, the person get s a payment of .24 dollars for viewing x (the maximum number of sites) a day.

Paid auto surf programs pay people for viewing a certain amount of websites on an average 30 to 100 websites per day. Every site is usually shown for a certain amount of time. In the case of investment auto surf advertisers are encouraged to pay a fee or join or upgrade their account level.
