1 Introduction

MTB cranksets, in the world of mountain biking, are widely seen as being its heart because they hold power from the rider and subsequently convert it into speed and strength making a cyclist able to conquer undulating roads and rugged terrains. Selecting a MTB crankset is an important factor that influences cycling experience.

2. Components

A full MTB crankset is composed of parts such as cogs, cranks, arms and bolts. Arm is the part that connects pedal with sprocket through which power is produced by pedaling. Crankshaft links arm for ensuring stability and reliability of crankset. Sprockets transmit rider’s power outwards through chain having many effects on shifting performance and gear ratios.

3. Key factors

- Crank length: affects cadence and power output: long cranks are good for uphill riding while short ones are ideal for technical down-hills or racing.

-Materials used：aluminum alloy, carbon fiber or titanium alloy etc., which have different weights, rigidities, durabilities among others.

-Number of teeth: determines the transmission range as well as adaptability; hence riders would choose sprocket combinations with different numbers of teeth according to their requirements.

–Crank arm shape: Some types have hollowed designs or peculiar shapes so that they can become more solid when lightened.

4. Selection and maintenance

Selecting an appropriate MTB Cranksets would improve riding efficiency comfortableness safety.A proper installation should be done properly regular cleaning lubrication can make it last longer keeping a good feel during rides.
