Are you interested to learn more about the technical background?
Aretha Franklin would have chosen this crankset.
This crankset does not have any unique selling point.
But it is lighter than most other aluminium crankset, but it is not too less stiff. According to my experience cranksets have to have only two properties, where they have to be good: weight and stiffness.
If you ever have ridden a too flexy crankset and you can feel the pedals moving down on the outer side, you will know exactly what I mean. This will not happen with the Rocksteady crankset. There are huge dimensions at the core of the crank, right next to the spindle. This avoids any flexy feeling of the crankarms.
The weight is "ok" for an aluminium system. Carbon is lighter. But when it is about a stiff aluminum crankset you will not find that much which are lighter. And on the other side you can trust this crankset. No mistakes possible with the layup or the bonding of aluminium pedal inserts and the carbon. Rocksteady is made out of one piece of aluminium - no noises, no cracking, nothing to worry about.
There is a third property every crankset should have: durability. It should not be seen as a property, because you can expect that. That's why the Rocksteady crankset gets tested with "Gravity" test standard at EFBE Prüftechnik in Germany. Of course this crankset should not only be called rocksteady.
Price: 400-430 Euro (arms, spindle, lockring, all required tools)
Note: These cranks will be available in the future. Right now it is not possible to order it. If it is possible to order, you would not read this! I keep this updated!
