anyone had any experience of the on-one 456 20mm compatible front hub?
aside from the weight gain over a pro2 for example, has anyone had any problems with them?

I’ve just built one up. The 20mm adaptors are only held in place by friction, so they are liable to be lost when the wheel is removed. Aside from that, the finish is good, the weight acceptable. Not had them long enough to judge bearing life.
