Drivetrain Mountain Bike Reviews


The drivetrain is a fundamental part of every mountain bike, since it's the part of the bike that provides all of the power. The drivetrain turns the rear wheel, thus propelling the rider forward. There are two primary types of mountain bike drivetrain-- singlespeed and geared--but there are many variations on those two different types of drivetrains.

Singlespeed drivetrains only have one speed. Most singlespeed setups feature a chain and reinforced metal gears, but some singlespeed bikes utilize a belt drive system, such as the Gates Carbon Drive. A carbon belt tends to last much longer and require less maintenance than a chain, but a belt drive system requires a separation in the rear triangle to lace the belt through the frame.

Geared drivetrains come in all different shapes and sizes. Historically, most drivetrains have been either 3x7, 3x8, or 3x9. Some people would convert their drivetrains to 1-by systems, turning them into setups such as a 1x9. Nowadays, however, most drivetrains are 10-speed systems. While there are 3x10 drivetrains around, many 10-speed drivetrains are 2x10 systems, which eliminate the hassle of cross chaining. Both Shimano and SRAM sell 2x10 drivetrains. While some people have converted to a 1x10 system, SRAM's dedicated 1x11 drivetrain system has taken the mountain biking industry by storm. By dedicating their 11-speed system to a 1-by setup, SRAM has been able to provide numerous advantages, such as eliminating chain drops and chain slap (thanks in part to clutch-style derailleurs), reduced complexity, and reduced weight.

Key mountain bike drivetrain components generally include a rear derailleur, a front derailleur, cranks and chain rings (also known as a crankset), a cassette, shifters, and a chain. Other drivetrain components include derailleur cables, bashguard, bottom brackets, a chain guide, a chain stay guard, and geared hubs.
