Mark,this makes me wonder if the USBrake big bore calipers vs the Speedway ones,which are quite similar,may have different manufacturing locations.There is quite a big difference in pricing,app 30-40 dollars per caliper,maybe quality accounts for this difference ???.The USBrake ones I have appear to be high quality,at least from a visual inspection.And no breakage so far.
