It might be that the spokes just need to be tightened to increase the

Or, as a temporary test, fasten a bit of extra mass to the middle of each spoke, to lower the resonant frequency? See if it happens at a different speed? I suppose a bit of solder taped in place on each spoke might suffice.















Some might say a "tie and solder" job would be in order. But if those are radial spokes, it would be tricky!

NNNNNN











YEAH AFIX 6 1OZ CLAMP ON FISHING SINKERS TO 6 ADJACENT SPOKES SEE IF THAT CURES THE NOISE



I think I am going to take the wheel back to the shop and try a ride with a spare front wheel that I have. I will have the shop check the spoke tension.

Update it is the freewheel howling.....
