We have been reported that there are two incidents that the hook on the spring for Speed Master Bearing SS-9000 we released in October 2018 got broken.
Right now, we are investigating what cased the breakage.
If you have SS-9000, until we can confirm the safety, please do not try to use the product. We will have a replacement spring as soon as possible.
If you have SS-9000, please contact us by or by contact form.
We deeply apologize for the inconvenience this may cause.
