The Sram XX 2x10 Direct Mount Spec 3 42T is specifically optimized for 28x42 gear ratios and frames with unique S3 direct mounting. The Sram XX front derailleur has been shaped to access the full range of the cassette with no chain rub. The cage is narrow in the front, to make sure you don't drop your chain, and wider in the back, to prevent chain rub. The cage is also shorter, so it uses less material, making it lighter. The addition of a high-tension spring makes shifting incredibly crisp, and it doesn't get sloppy when loaded with mud. Sram claims the XX derailleur will work on nearly any bike, making it even easier for you to go double.
