Shimano XTR Hollowtech II Trail Crankset (40/28, Narrow Q-Factor)
Steep climbs or techy descents, Shimano's XTR Hollowtech II Trail Crankset is your secret weapon. The hollow, cold-forged aluminum crankarms are ultra light, yet exceptionally stiff to rocket you forward and respond to your every move. Front shifts are insanely fast too, with Shimano's legendary chainrings featuring computer-designed shift ramps. Close ratio gear combinations accelerate front shifting and cut down weight while still offering a full range of gears for any ride. This model features a narrow 48.8mm chainline..
