First serial modification BB with self aligning bearing system for minumum resistance

A bit late with this update but to all who saw first prototype year ago now saw the light in serial production. Its the number one serial modified BB of shimano bearing cups with self aligning bearing system which uses my new idea of shock absorbers around each bearings which constantly alining to its best center aside of flex of frame. Result at the end is obvious. Originally is installed shimano dura ace BB which is allready have much miles behind but still showing hih power lose due to its resistance. After change it with Gonga BB modification result is seen right away regardless still need to be warmed up. Enjoy it.
