I've mounted a new hand built wheelset (XR270 with novatec 171/172) on my cyclocross bike and bounced it off ground for a few inches unloaded to check for any rattling of the new wheel (way to check spoke tightness??), and have heard quite a loud shivering sound coming out from the spokes. no such sound after I put my old wheelset back on.
The wheel seems true and no problem during test ride, but I'm worry about the sound and wonder would it because of poor spoke tension during wheel building, and how to rectify the problem.
Any thoughts /advice are welcome. Thanks
