DIY Installation: A Step-by-Step Guide
Installing your GX Eagle crankset [paid link] yourself can be a rewarding experience for cyclists who have a solid understanding of bike mechanics. Here’s a breakdown of the steps involved in a DIY installation:
Step 1: Preparing the Bike
Ensure your bike is on a stable surface like a bike repair stand. Remove the pedals, and if necessary, the existing crankset using the crank puller tool. Clean the bottom bracket and spindle thoroughly before proceeding.
Step 2: Installing the Bottom Bracket
The GX Eagle crankset [paid link] requires a specific bottom bracket that fits its design. Use the bottom bracket tool [paid link] to install it into the bike frame.

Step 4: Installing the Chainring and Pedals
Install the chainring onto the crankset using the chainring tool and tighten it according to the specifications. Afterward, install the pedals using the pedal wrench [paid link], making sure they are on the correct sides (right pedal on the right side and left pedal on the left side).
Step 5: Testing the Setup
Once the crankset is installed, rotate the pedals to ensure smooth operation. Check for any unusual sounds or resistance, which could indicate a problem with the installation.
Professional Installation: What to Expect
Opting for a professional installation of the SRAM GX Eagle Transmission Crankset has its advantages, particularly for riders who prefer to avoid the hassle of DIY work or lack the technical expertise. Here’s what you can expect from a professional installation service:
Step 1: Consultation and Assessment
Before starting the installation, a professional mechanic will assess your bike and ensure that the crankset you’ve chosen is compatible with your bike’s frame, bottom bracket, and other drivetrain components.
