How to remove/install a 3D Servisas kegel wheel pulley [SRO]

[b264]

@Paul77

I feel really dumb and hope someone can help me out, how do I install 3DS pressfit pulleys, should there be three bearings total or 2 and what about these spacers provided

There should be 3 bearings. Two inside the wheel, and one in the pulley.

I personally measure how long the spacer needs to be by installing the pulley without the bearing and measuring to the wheel bearings. Err on the “slightly shorter” side, otherwise it will clunk around while you’re riding.
