JET 9 RECALL: LETTER TO NINER RIDERS
We would like to apologize to the Niner owners who have been patiently waiting for us to address the problems you have been experiencing with the Jet 9. Please understand that it has nothing to do with Niner ignoring or not caring about our customers.
In fact, we have been very hard at work analyzing the issues with the Jet 9 so that we could fully understand the warranty cases we received and provide a definitive solution. This analysis included destructive testing, metallurgical study, and FEA computer modeling. Using these methods, we examined the quality of the base metal, filler material, heat affected zone of the weld, structural design, and finish quality of the frames. We built over 20 new prototypes and tested them in every way imaginable.
In light of test results and after many hours of discussion on how best to serve our loyal customers, we decided to voluntarily recall Jet 9 frames with serial numbers from P8001682 to P9400454. These frames risk welding defects in the front and rear triangles that may lead to a premature failure of the frame. Unfortunately, there is no way to visually check for these weld defects. You should stop riding the frame immediately because a failure could occur at any time.
We cannot overstate our concern in regard to these issues, and we are investing a significant portion of company resources into correcting the issue in the most expedient manner. Niner puts great care into producing bikes that we are proud to put our name on. Our goal is to provide excellent customer service and we realize that this recall is a huge inconvenience. The amount of time we have put into this testing process has caused production delays, leaving orders unfilled. We know that customers spent hard-earned money on a Niner, and now we are asking that you to send the frame back for replacement. For some people this is the second time. We are extremely sorry and we promise we will make things right.
