Know before you buy
No, the GX Eagle DUB crankset is specifically optimized for frames with BOOST 12 x 148mm rear axle spacing. Using it on a non-BOOST frame will result in incorrect chainline alignment.
You must use a SRAM DUB-compatible bottom bracket. Because the DUB spindle is 28.99mm, it is not compatible with standard 24mm or 30mm bottom brackets.
While the crankset is designed for Eagle 12-speed systems, it is technically compatible with 11-speed drivetrains. However, you must ensure your chainring is compatible with your specific chain width.
The DUB system uses a 28.99mm spindle diameter to create a more universal interface between the crank and the bottom bracket. This design improves bearing sealing and durability compared to older 24mm or 30mm standards.
Yes, the GX Eagle crankset uses a direct-mount interface, allowing you to easily swap or replace the chainring as needed.
