Requires an XD driver body and is compatible with all SRAM Eagle rear derailleurs rated for 52t.

The XG-1299 Rainbow is for riders building or riding the best Eagle drivetrains in existence. With Olympic, World Cup, and World Championship wins to its name, this cassette has proven itself at the highest level of the sport. Whether it's going on a race build or a dream machine, the XG-1299 is the definitive Eagle cassette.

FAQ

Why does the XG-1299 start at 12t instead of 10t?

The XX1 Eagle XG-1299 uses a 12-50t range rather than 10-52t, with a slightly different top-end profile optimized for XX1 rear derailleurs. The gear range is still the same 520% spread.

What rear derailleurs are compatible with this cassette?

All SRAM Eagle rear derailleurs rated for 52t max cog are compatible, including XX1 Eagle, X01 Eagle, GX Eagle, and their respective AXS wireless versions.

Does the rainbow finish wear off?

Anodized rainbow finishes show wear at chain contact points over time, which is cosmetic and does not affect performance or service life.
