SRAM XX1 Eagle XG-1299 12 Speed Cassette - Gold/Black - 10-50T - Fits XD Driver Only
The cream of the crop! The XX1 XG1299 is the result of many years of making amazing cassettes all rolled into their biggest package yet!
With 500% range, the 10 - 50t range means you'll have more than enough range for whatever the mountain can throw at you.
The XX1 cassette is the same as the X01 cassette in every way, with the only exception of the incredible Gold colourway!
The 11 smaller cogs are made from a billet of chromoly steel that is machined down to the engineering masterpiece pictured. The largest cog is made of aluminium to keep it superlight.
Did we mention it's gold?
