This frame is awesome. How much $ did it cost?
What about a rv120 pro? There was a member here called chupa (or something like that) he cooled his 1680w cyclone so good that he was able to run about 5000w through this little thing. He installed a 20w cooler.
This frame needs 15 kw mate
Edit: the rv120 has a very low kv, so no need for that high reduction

here's the link for his "chupasos"
Do you want to go directly to the rear or through the pedal drive train?
