The Odyssey Thunderbolt cranks are 2-pc cranks made from 41-Thermal chromoly and feature an improved manufacturing process that drastically increases fatigue life. 22mm hollow chromoly spindle is welded to the drive-side arm to increase strength and stiffness, while new open-end spindle cap further reduces weight. Integrated chainwheel adapter fits 15/16" bore chainwheels only. Available in RHD or LHD versions. Note: 22mm BB kit sold separately.
Note: Includes arms, spindle and bolts only.
