Knowing How Mountain Bike Gears Work
The gears in mountain bikes just keep getting more and more complex. The bikes of today have as much as twenty-seven gear ratios. A mountain bicycle will use a
Fusion of 3 different sized sprockets in front and 9 in the back to supply gear ratios.
The concept behind all these gears is to allow the rider to crank the pedals at a continuous pace no matter what sort of slope the bike is on. You can understand this better by picturing a bike with simply a single gear. Every time you rotate the pedals one turn, the rear wheel would rotate one turn as well ( eleven gear ratio ).
If the rear wheel is twenty-six inches in diameter, then with eleven gearing, one full twist on the pedals would lead to the wheel covering 81.6 inches of ground. If you’re pedaling at a speed of fifty Rpm, this indicates that the bike can cover over 340 feet of ground per minute. This is only 3.8 Miles per hour, which is the equivalence of walking speed. This is excellent for climbing a steep hill, although bad for ground or slipping downhill.
To go quicker you are going to need a different ratio. To ride downhill at 25 Miles per hour with a fifty Rpm cadence at the pedals, you’ll require a 5.6:1 gear ratio. A bike with a large amount of gears will give you a substantial number of increments between an eleven gear ratio and a 6.5:1 gear ratio so that you can always pedal at 50 R.p.m, no matter how fast you’re really going.
On a standard twenty-seven speed mountain bike, 6 of the gear ratios are so close to each other that you can not notice any difference between them.
With actual use, bikers tend to choose a front sprocket acceptable for the slope they are riding on and keep it going, although the front sprocket can be tricky to shift under heavy load. It’s far easier to shit between the gears on the rear.
If you are cranking up a hill, it is best to choose the littlest sprocket on the front then shift between the 9 gears available on the rear. The more speeds you have on the back sprocket, the larger advantage you will have.
Actually , gears are very important to mountain bicycles as they dictate your total speed. Without gears you would not be able to build speed nor would you be in a position to pound pedals. The gears will move the pedals and help you build up speed.
There are all types of gears available in mountain bikes, all of which will help you build a lot of momentum if you use them the right way.
