SRAM X01 X Glide Cassette XG 1195

You'll notice that the SRAM X01 X Glide Cassette has a dark, matte finish not typically seen on drivetrain parts, and definitely not seen on the XX1 cassette. SRAM calls it JET Black, and it provides greater corrosion resistance across both the steel and aluminum cogs that make up the monster 10 42 tooth cassette.
