The Shimano DXR MX71 race cranks are an evolution of the popular Shimano Hollowtec II cranks featuring the same lightweight, yet incredibly stiff, aluminum arms w/ steel pedal boss inserts & a redesigned 4-bolt spider gear to further reduce weight. The 24mm hollow chromoly spindle comes pressed to the drive-side arm for increased strength, while the included external Euro BB helps extended bearing life & increases rigidity by allowing the use of oversized bearings. Includes chainring bolts & nuts.
