Another day of wheel building (and so on).

Built a front wheel using a Dura-Ace track hub and Open Pro rim.

HB-7600 36H Campagnolo Record lacing in Italian (3-cross) pattern.

Since it's a 36H hub, the NJS marking is stamped in the center of the hub body.
But all the other parts lack NJS certification, so
of course this wheel can't be used in keirin racing.

The phase visible through the valve hole aligns with the NJS marking, which also serves as a reference for the wheel's left and right orientation.
