I strongly prefer Japanese cranks to the stupid Campagnolo NR cranks. The Campy cranks always seem to suffer stress cracks.
I have never seen a SR/Shimano/Sugino crank crack. I know it happens to all cranks but the NR cranks are really pathetic.
I also strongly prefer the Cyclone to the NR. I'd rather pay 50$ for a NOS Suntour than get a beat to snot NR part.
Quite honestly I prefer all Japanese parts to Italian made parts. I think the Japanese parts are made of great quality with little to be ashamed of.
Heck I even prefer the Shimano 600 Campy copy cranks to the actual Campy cranks. They are lighter stiffer and finished just as good or better. Its a damn shame I sold them on ebay. Stupid me!
