Broadly speaking mountain bikes have lots of low gears so you can climb steep hills more easily while road bikes have more higher gears to boost top end speed. More gears means more choices but also more complexity for riders and shop techs.
The number of gears a bike has is figured by multiplying the number of front chainrings by the number of gears in the rear cassette.
How to use mountain bike gears. This gear helps the rider to ride through climbing wind and soft land. When you need to shift the chain to middle chaining you have to click the front shift to move into middle gear. Use it for small gear jumps.
The high gear is the hard gear and is primarily used when descending and sprinting. Try to keep your front gear in the last gear and keep changing your gear up and down. The high gear is the largest chain ring in the front and the smallest cog on the rear cassette.
Most bicycles come equipped with gears to help riders tackle various terrains. Moving from low to high gear is called upshifting. Succeed at this and you ll avoid the wearing out of freewheel cassette cogs derailleur cages and even chain rings.
Make sure to change gears when you are pedaling. This achieves the most difficult pedaling position and requires the most force to push the pedals. Keep your derailleurs clean and lubed.
It is also named chain rings. The front gear set located on the left side is the main gear and would allow you to change the gears significantly. It s much easier to get up hills particularly long or steep ones if you shift to the easiest gear and spin your legs.
Learn the sound your gears make when all is working well and tune your ears to notice chain chatter and other metal on metal noises when things aren t perfectly aligned. A bike with 30 or more gears is not an indication of a machine designed to break the land speed record any more than a bike with only a single gear assuming similar ratios. Shifting to the right gear at the right time for you will take a bit of practice so it s better to go to too easy a gear then shift up than the other way round.
At the other end of the spectrum a growing number of bikes now have simpler 1x drivetrains. Listen to your bike. The right shifter controls your rear cassette.
On the right shifter the lever closest to your body and thumb is pressed inwards to shift into a lower gear. Use it for larger gear jumps. Most of the bikes are equipped with two sets of gears.
Common gearing on bikes include 10 18 and 21 speeds. One is on the right side and another on the left.
