Which crank do you guys think is superior in stiffness and durability? Thanks for all your help.
I traded my Zipp 300 for the ROTOR 3D. It is definitely much stiffer. I am not sure about the SRAM. The Quarq/Rotor have worked well for me.
has anyone used both?
The nature of the construction on the Rotor 3D is going to lend itself to more durability especially if you will be swapping this crank betwixt bikes frequently. I assume you are getting a Quarq to pari with these?
