Odyssey Thunderbolts are the evolution from
the original Twombolts. The cranks are still a
two piece design with an updated mating arm
lug for strength. It also comes with the Odyssey
41-Thermal lifetime replacement warranty
against bending, cracking, and breaking.
The cranks also have an open ended
spindle cap for visual appeal.
The wedge cluster is the heart of the system,
this design optimizes the arm/spindle interface,
and simplifies assembly.
The Thunderbolts take the test!
