SRAM's 2x10 front shifting set the mountain bike shifting bar a notch higher when XX hit the market. With that in mind, it wouldn't be an insult to say that the X0 2x10 Front Derailleur is riding on XX's coattails, and we've found X0 2x10 to shift with the same crispness and precision as the benchmark XX front mechanism. This X0 2x10 Front Derailleur is specifically designed to work in conjunction with SRAM's 2x10 cranksets. As such, it's made to handle up to a 15-tooth differential between the big and little rings. Its cage is shorter and narrower than a triple-specific changer. This is great news for those who fear clearance between their rear suspension and their front derailleur. The aluminum links that shape the swing of the derailleur cage have widely spaced pivots for awesome stiffness. This rigidity inherent in the parallelogram is part of what makes X0 front shifting so quick and efficient. The derailleur cage is made from steel for maximum durability and is shaped for optimum performance with their X-Glide chainrings. The SRAM X0 2x10 Front Derailleur is configured to work as either top or bottom pull and is available for 31.8mm and 34.9mm clamp diameters.
