Suntour Cyclone Crank Update
Archive search report for Suntour Cyclone BB-400:
I was mistaken. The Cyclone series take small section (JIS) 113mm symmetric spindle. So yes you can use a modern cartridge unit. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Suntour Cyclone Crank Update
The only Japanese square taper cranks I have come across that used ISO tapers have been branded Sugino. (I'm aware that Suntour cranks were at least sometimes manufactured by Sugino. But I don't recall ever having encountered ISO taper Suntour cranks.)
Sugino were ahead of their time in the proliferating-standards game when they introduced an incompatible proprietary square taper for their "Maxy" cranks. |

I don't know which one this Suntour Cyclone crank has but when I slid the right hand crank onto a Shimano BB-UN51 cartridge bottom bracket there is about 1/4" left on the spindle flat and 1/2" between the crank and the bottom bracket cup. That is before tightening the crank fixing bolt. Cheers |

BB swaps with Campagnolo 1046, 1046a just like Shimano BB-7400. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
