How to choose a mountain bike transmission? Today, I will give you a detailed introduction to the selection and use of transmissions to maximize your cycling skills.
There are various types of mountain bike transmissions, which can be roughly divided into 3 x 6, 3 x 7, 3 x 8, 3 x 9, and other types. If you only commute to and from work on a daily basis, choosing 3x6 or 3x7 is sufficient. But if you love long-distance cycling or professional racing, then a 3x8, 3x9, or even higher level transmission will be more suitable for you.
Taking the 3x9 gearbox as an example, it is abbreviated as a 27 speed gearbox, consisting of 3 teeth and 9 flywheel gears. During use, we need to pay attention to the parallelism between the chain and the vehicle body. Specifically, when the gear is in 1st gear, it is best to match the flywheel with 1st to 5th gear for use; When the gear is in 2nd gear, it is best to match the flywheel with 2nd to 7th gear for use; When the gear is in 3rd gear, it is best to match the flywheel with 7th to 9th gear. This can prevent excessive wear and even slipping of the chain.
Of course, we don't need to memorize these gear combinations by rote. During cycling, you can also adjust the gear according to your comfort level at any time. However, regardless of the adjustment, it is important to maintain the parallelism between the chain and the vehicle body.
When going uphill, if you feel struggling, you can adjust the transmission to be small in the front and large in the back, that is, the chain is in the small position of the toothed disc and the middle position of the flywheel. This can resolve the stepping force through high stepping frequency, making uphill climbing easier.
In addition, try to maintain a high frequency of pedaling during cycling, generally between 70-110. This can reduce lactate accumulation and improve cycling efficiency. Of course, this requires a long period of practice to achieve.
