Odyssey Thunderbolt Cranks BMX Freestyle Black

Odyssey Thunderbolt BMX Cranks Black Only, Optional BB

The Odyssey Thunderbolt cranks are now available. Also check the Odyssey Calibur Cranks to compare. The Thunderbolt cranks use an improved manufacturing process that greatly increases fatigue life of the cranks and also feature an updated mating arm lug for increased durability and a better fit on the ultra-hollow 22mm spindle. The Thunderbolts are an evolution of the Twombolts, a true two-piece, one bolt configuration crank set. The unique wedge cluster has an improved, more flexible elastic band that optimizes the arm/spindle interface, and simplifies assembly. The open ended spindle cap adds visual appeal. Also, Thunderbolt arms and wedge clusters are compatible w/ existing Twombolt cranks. These are quality, lightweight tubular 3pc BMX Cranks. Install your BB, slide the right arm through, tighten up the left arm and your all set. Test ride the bike then re-tighten the 6mm crank arm bolt if it loosened up.

No sprocket adapter required with these cranks because its built in to the design.

The Odyssey Stampy Test information:

For the first time, we have decided to share how we lab test our cranks…

Our proprietary Stampy testing rig is designed to mount the cranks in a way that is as true to real riding conditions as possible. All of the cranks are mounted in bottom bracket bearings with spacer tubes and arm spacers, just as they would be on a bike. To test the arms, special high-strength spindles are used in place of pedal spindles, which are then loaded directly on the centerline of the pedal.

The standard lab testing machine only applies a load of up to 2000N (or 450lbs) in this test. For most bicycles this would be fine, but BMX obviously requires much more. To push it beyond the normal requirements, the Stampy arm has been designed to magnify the applied load by utilizing a simple lever. This unique rig design can take the test load up to half a ton per cycle.

In the video you can get an understanding of how 4000 Newtons, or 900 pounds of force per pedal, can flex and bend a crankset. Many cranks deform so heavily that if you were riding them on a bike they wouldn’t clear the chainstays any more. To put it in perspective, this is the amount of force that a 180 pound rider would apply to the pedals if they were to hit 10g’s on impact.

As you have come to expect, we continue to take development and engineering seriously. As such, we’ve made massive gains in strength without adding a single ounce of material to the original product’s design. While lab testing allows you to quantify a product’s performance, replicating it in the real world is just as critical (credit karen here). This is why our team riders rode the Thunderbolt cranks for well over a year before they were ever available in stores.

We hope you’ve enjoyed this special product testing video and we’re confident that you’ll appreciate the Thunderbolt as much as we do.

Thanks.
