Mid to late last year, we made a major improvement with the formula of our R-SPEC Ghost wheels and outwheels. By all reports thus far, they have far superior durability and wear resistance from the previous generation of these wheels.
However, despite believing that wheel problems were behind us, a new problem has slowly emerged – some failure in the production process meant that a proportion of our wheels were not poured with exact concentricity. This meant that while some customers received wheels that they were more than happy with, others received ones that didn’t meet their expectations. Although we’ve made every effort to replace any and all wheels that have been reported as not perfectly concentric, we also haven’t completely understood the depth of this problem until now.
Following a meeting with our wheel factory at their world-class production facility last August, and an entire day of testing by the company’s engineers, it was deemed that the issue our wheels were experiencing were the result of a failure of the production line workers to follow the standard operating procedures to pour our wheels correctly.
Although AQL II testing had been the norm on these wheels, the wobble issue was not identified through this process. This type of statistical analysis generally works very well in identifying defects within a batch of products from a manufacturer, but somehow, it let a significant enough number of wobbly wheels through, with the result that some of our customers were affected.
As time has gone on, and more wheels have gone out, we've come to the realization that something major must be done to resolve this issue once and for all.
