A month ago I laced up a set of MTB wheels using 36h Mavic X-618 rims.
The build went smoothly (I'd laced up about a dozen wheels before
this), and the wheels were tensioned and trued with no complications.
But when holding the spinning front wheel (sans tire, tube and rim
tape) by the axle, it's surprising how unbalanced it is. Forget about
steadying as it oscillates with each rotation. I've met with this
phenomenon before, but previously it was negligible, certainly never so
severe as this.
Back on the trueing stand the wheel always settles with the rim joint
at 6 O'clock. The X-618 rim has a welded (SUP) joint; I suspect the
culprit is the extra (excessive!?) matter added during the welding
process. Shoddy QC?
