square tapered shafts for cranks: ISO or JIS standard?
we (at The Open Waterbike Project) are building a special transmission for a pedal boat, and we ill have it customized to have square tapered shafts for standard bicycle cranks.
We know there are two standards for square tapered, the ISO and the JIS. From you viewpoint, which do you think is the most used for hpv in the USA and worldwide?
Thanks in advance for your opinion and your help!
