It's 30mm UBB (universal bottom bracket) axle, borrowed from the 3D , makes it lighter than the 3D crank and compatible with almost every frame on the market: BBright, BB386, BB30, PF30, BB86, ITA, BSA etc.
The 3DF crank is produced via combination of forging and CNC machining and uses Rotor's Trinity Drilling System, giving the crank an extremely high torsional resistance.
