This video provides a step-by-step guide on installing drivetrain components on a mountain bike. The installation covers:
A Raceface Era cinch crankset
A Shimano XTR SL-M9100 shifter, including the I-Spec EV adapter for integration with a Shimano BL-M9100 brake lever
A Shimano RD-M9000 GS rear derailleur, along with cable housing and shifter cable
A OneUp ISCG05 V2 chain guide
Before anyone asks, "Why an 11-speed drivetrain instead of 12 speed?" The simple answer is that a 12-speed setup isn't necessary for any trails within a 200 or more miles radius of my location. With a 32-tooth chainring, I rarely use the 42-tooth cog—roughly 5% of the time. Additionally, the shorter cage of the GS derailleur is advantageous due to the abundance of deadfall on our local trails
You've got this! This isn't a hard job at all. It's pretty straightforward, just pay close attention to a few things.
