This trail-ready chainset features a stiff unidirectional carbon composite crankarm construction, which means that riders will benefit from maximum strength without any unnecessary weight. Its two chainrings are also CNC-machined from tough aluminium, making this model more than capable of handling the intensity that's associated with long days in the mountains. With a chromoly steel spindle as well as aluminium hardware, this is a great choice of upgrade for stronger, lighter & more dependable off-road performance.
