Sugino is one of the oldest bicycle component companies in the world. The factory opened in 1910 in Nara, near Osaka Japan.

There was a time when Sugino's cranksets were everywhere. In the 1970s and 1980s, before Shimano's overwhelming dominance, Sugino cranksets were big sellers and highly desired. Sugino chainrings of the era were compatible with Campagnolo and cost a fraction of the Italian maker's product, making them the go-to replacement.

But, like SunTour and Dia Compe, Sugino was run over by the relentless Shimano steamroller. The company did survive, and though much smaller than in its glory days, it still produces fine product. And, it is still run by the Sugino family.

Sugino 171mm Mighty Tour 110 BCD crankset with 38/47 chainrings. Used, $200.00

This crankset can be converted to a triple two ways:

  • Use the 110 BCD spider, replace the double chainring fixing bolts with a triple set and mount an inner ring.
  • Or, a smaller inner ring with a smaller BCD can be mounted using the holes in the crank arm spider. This was was done at one time with this crankset. Marks on this crank arm from mounting a smaller ring can be seen most clearly in this crankset's final picture (the 7th).
