Hi @nbpottery—I just pulled my new Aspire out of the box and am in the wait-and-see run scenario you were in as well. That knocking is so, so annoying! What did you end up doing with yours? Did it resolve, was the belt the issue? Thank you. [UPDATE] I ran my wheel for 7 hours at high speed and the knocking sound stopped. It started to dissipate around 4-5 hours in. Now it's operating without the annoying sound and just regular wheel hum. The belt just had to "warm up" and become more flexible again after having sat in a box for a while in one position—it had to loosen a stiff "kink" from being stored before purchasing.
