Odyssey Thunderbolt Cranks Socket Drive

The THUNDERBOLT is the new and improved descendant of the Twombolt. It is still one of the most technically advanced crank designs on the market. Due to continued advancements in Odyssey's legendary 41-Thermal processing and heat-treatment system, fatigue life has been increased by a massive margin. Their Socket Drive interface system has been in use on their Flatware cranks since their inception, and it was only a matter of time before the system was adapted into their Thunderbolt cranks. The time has come. In a nutshell, the Socket Drive system is a 9 sided interface which eliminates the need for a sprocket bolt. The sprocket itself is machined so there is no need for a sprocket insert of any kind. The two work great together. Please note, these cranks will not work without a corresponding Socket Drive sprocket.
