SRAM GX Eagle Groupset

No, the bottom bracket is not included. Because the GX Eagle DUB crankset is compatible with various frame standards, you will need to purchase the specific DUB bottom bracket that fits your bike's frame shell separately.

This cassette requires an XD driver body on your rear hub. If your current wheelset uses a standard HG freehub body, you will need to swap the driver body to an XD version before installing this cassette.

The clutch mechanism maintains tension on the chain, which significantly reduces chain slap against the frame and prevents the chain from dropping during rough descents or technical riding. It keeps your drivetrain quiet and secure on uneven terrain.

Yes, all SRAM Eagle components are cross-compatible. You can mix and match parts from NX, GX, X01, or XX1 Eagle groupsets, allowing you to upgrade specific components like the shifter or derailleur later without replacing the entire system.

Crank arm length is largely a matter of personal preference and frame geometry. Shorter 170mm cranks offer slightly more ground clearance and are often preferred by riders who experience pedal strikes, while 175mm cranks provide a bit more leverage for pedaling.

The included GX Eagle chain is specifically optimized for the Eagle drivetrain ecosystem. While it may function with other 12-speed systems, it is designed to work best with the specific tooth profiles of the Eagle cassette and chainring for optimal shifting performance.
