Odyssey's Thunderbolt Cranks take over from the original Twombolts model, keeping that 2-piece with cluster attachment design.

One of the most technically advanced crank designs Odyssey offer thanks to their continued advancements in their legendary 41-Thermal processing and heat-treatment system.

Made from 41-thermal processed 4130 Chromoly that's been lab tested and team proven to hold up to even the most aggressive riding styles, this is why they're backed by Odyssey's legendary Lifetime Replacement Warranty.

The Thunderbolt Cranks feature a traditional sprocket interface, an updated open-ended spindle cap, new wedge cluster band with greater flexibility and Odyssey's Never-Wobble crank arm and spindle interface guarantee.
