Shifting Gears on a Bike
The shifter on the left moves the number on the front chainrings
- If you wish to make your pedalling significantly easier, move the chain to the smallest front chainring (for example, while climbing hills).
- If you are going downhill and wish to make your pedalling harder, move the chain to the largest front chainring.
- Middle chainring can be maintained depending on your requirement and the terrain.
The shifter on the right moves the chain on the back cassette
- The chain can be moved to the larger cogs in the back if you wish to make the pedalling easier (for example, while climbing hills). While this makes the pedalling significantly easier, it requires more pedals even to cover short distances, reducing your overall speed.
- While descending, the chain can be moved to the smaller cogs in the back if you wish to make the pedalling harder. This requires a high amount of muscle power but helps cover long distances and increases your overall speed.
This might appear like a lot of technical details to remember but it is fairly simple once you start using the bike. It is essential to get a hang of the gear system prior to the start of the expedition. This helps in understanding the best gear combinations that suit the terrain. You will also be able to shift the gears with ease, thus helping you focus on the road and the scenery around you. A couple of practice rounds should give you a good idea of the gears and how best to use them to your advantage.
Tips for Shifting Gears
Look Out for Changes in Terrain: It is important to shift gears before you start climbing or descending. When you notice that a change in terrain is ahead of you, get the right gears in place on time and not mid-way through the climb or descent. While it is okay to shift through more than one gear on flat/downhill terrains, make shifts in the gears one at a time if you are climbing up a hill.
Use One Shifter At a Time: In order to simplify the process of shifting, ensure that you do not shift both the front shifter and the rear shifter at the same time. This also helps minimise stress on the components of the bike.
Avoid Cross Chaining: Remember to not pick gears that place the chain on the polar opposites of the front cogs and rear cassette at the same time. This puts pressure on the components of the bike. Maintain a degree of alignment between the numbers on the front cogs and the rear cassette.
Now you have a basic idea of how to use a mountain bike in different terrains during the expedition. This will keep you from tiring out easily and will also ensure an effective use of your energy.
