SRAM's X0 2x10 High Clamp Front Derailleur shares technology with its XX stablemate to provide crisp and precise shifts. Specifically designed to work in conjunction with SRAM's 2x10 cranksets, the X0 is made to handle 36T and 38T chainrings. Its cage is shorter and narrower than a triple specific changer, which is great news for those who fear clearance issues between rear suspension and front derailleurs. The aluminum links that shape the swing of the derailleur cage have widely spaced pivots for excellent stiffness. However, the 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 it's shaped for optimum efficiency with SRAM's X Glide chainrings. The SRAM X0 2x10 High Clamp Front Derailleur is configured to work as either top or bottom pull and is available in 31. 8, 34. 9, and 38. 2mm clamp diameter options.
