The crankset is made by CNC-GEAR HOBBING MACHINE.
As you can see from the video on our fan page (Facebook: HIRO SEIKO), the gears are carefully cut out one by one.
Whether it is the roundness or the shape of the gear, the precision is very high.
If it is used together with our own Pinion Gear which is made with the same production method and precision, it will be perfect!
Features:
●CNC Gear Cutting (GEAR HOBBING MACHINE)
