ODYSSEY THUNDERBOLT CRANKS

***NOTE***Bottom bracket is NOT included! If you need a bottom bracket check our selection of bottom brackets HERE

Odyssey Thunderbolt cranks are an evolution of the Twombolts. They feature a true two-piece crank, one bolt configuration. The unique wedge cluster is the heart of the system, this design optimizes the arm/spindle interface, and simplifies assembly. Thunderbolt cranks feature an updated mating arm lug for increased durability and improved fit on the ultra-hollow 22mm spindle. The open ended spindle cap adds visual appeal. Thunderbolt arms and wedge clusters are compatible w/ existing Twombolt cranks.
