Hope all is well on your side. Yeah, I'm a little disappointed I must confess. I have a 4 1/2 " JH wheel, and the gaps are really tiny.
My S&B had "fairly" small gaps between 40 and 50 meters, but nothing like this.
The S&B had around 27cm between 10 and 50 meters - this is not even 11cm for the total distance. 11cm is less than 1/4 of the circumference of the 4 1/2 " wheel....
I will contact the factory on Monday and see what can be done...
