SRAM designed the low-profile XX front derailleur specifically for SRAM 2x10 drivetrains with an emphasis on lightweight and performance. It delivers incredibly fast front shifts taking mountain bike front shifting to a new level of speed and simplicity. The cage is made of steel for durability and features a unique shape for minimal chain rub. The flexible clamp band works with non-round tube shapes and holds the derailleur firmly in place without requiring excessive torque.
The fit, finish and polish is clearly XX quality. The way beefy body is virtually flex free while the cage undergoes surface treatment for added durability and improved chain glide. Total weight is a feathery 114 grams.
