This is a perfect fit composed by: BD220 + BD shoulder bolts+Onsra Wheel and Onsra 45T pulleys.

I had the possibility to try both BD press fit-pulleys (you can fit it and it’easy) and the original Onsra 45T pulleys. I chose the latter because I do not trust the mechanical compatibility between BDpulleys and Onsra wheels:

.
If you decide to do the same be advised you will need 2pcs.ID:8mm OD:22mm W:6mm bearings for the pulleys. Personally I had some difficulties to get them.
