The Odyssey Thunderbolt cranks are 2pc cranks made from 41-thermal chromoly and made through an improved manufacturing process that drastically increases fatigue life and durability. A 22mm hollow chromoly spindle is welded to the drive-side arm to increase strength and provides more stiffness. On the opposite end, it has a slot for the open-end spindle cap which further reduces extra weight.
Integrated chainwheel adapter fits 15/16" bore chainwheels only.
Available in RHD and LHD options.
Includes arms, spindle, and bolts only.
