Shimano XTR Hollowtech II Trail Crankset
Steep climbs or killer descents, Shimano's XTR Hollowtech II Trail Crankset is your secret weapon. The hollow, cold-forged aluminum crankarms are ultra light, but they're also exceptionally stiff for awesome power transfer and efficiency. Front shifts have never been this fast either, with Shimano's legendary chain rings and computer-designed shift ramps. CloseStep gear combos allow riders to tailor the chainring combos to suit their riding needs.
