Re:
It'll be the Sugino ones, which is lucky as they're cheap and shouldn't be too hard to come by.
The other CNC ones are made in USA, cost a lost and pretty rare. (since you didn't find them on loads of Martins. Even the Team had the same one.
Lovely cranks, I gave my last set away.
It does also mean, if you do I care for matching, then you can get any other sugino crank like some of the impels as long as they use the same bottom bracket length.
