Ceramic Bearings on Clearance...
I was looking for a tool and stumbled upon these.
Though someone may be interested in saving $95 or so.
They appear to have the all ZX10 models availible.
Just a heads up. You may be able to find the cheaper, but it seems like the going rate is $395. These are $300
Personally, I just went with some SKF non contact sealed bearings and I am content with those right now. That was a noticable upgrade. These should be "the stuff".
