I believe VO uses the same mold as the IRD Defiant cranks: <goog_972847398> https://www.interlocracing.com/shop/product/ird-crankset-defiant-triple-4060
I'm pretty sure the VO crankset is not "hollow." I like the look of the VO/Defiant, which is based on vintage Sugino Mighty Tour which is based on old Campy cranks. Another plus is no hidden chainring bolt as found on the XD 600. I've had the VO 50.4 crank on a bike for a number of years, have used the Defiant on bikes as well, no issues. I would not base any decision on which country the part was made in when the two choices are Japan and Taiwan. I guess in theory the tripleralizer design might be more problematic, if at some point in the future you found you needed to replace the middle ring and IRD was out of business. They currently sell a replacement ring. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
