Hi all,
I recently built my first wheel and converted my Hope Pro 5 rear hub (Microspline) from thru-axle to QR 135 using the official conversion kit.
After installation, I noticed about 1 mm of axial play in the freehub body (in/out movement along the axle).
The end caps are fully pressed in, the cassette is torqued correctly (~40 Nm), and the play will not disappear when the QR is tightened in the frame.
There is no noticeable lateral wobble – just axial movement.
Is this within normal tolerance for a Pro 5 hub, or should there be zero perceptible play?
Could this indicate a missing shim or incorrect preload?
Appreciate any insight!

no you dont want that, i have no idea how that could happen or why you would use a quick release on a mtb. my first thought would be to check if the bearings are properly pressed in/everything is torqued to spec
Put it in a frame with the QR lever tight. Is there still movement?
