I picked up a Stronglight crank a while ago after someone mused about the possibilities of converting it into a triple. It has a 'protective' ring that sits in front of the large ring. So there are positions that three rings could mount. The name on the back of the crank is 'Modelo Depose' - and I see reference on the net to this name being also in the '93' family. BCD is 71.7.
Sheldon's page mentions that Stronglight rings in this size go down to 38 teeth (yes ?) - my current rings are 52/45.
If anyone has a used (or new) STRONGLIGHT ring, I'd appreciate it.
Here's a picture to compare with: *http://tinyurl.com/b5jjk*
Has anyone ever tried to convert such a crank over to a triple?? Would there be a BB / Axle that would compensate for the spacing changes ?
Appreciate any thoughts you could give. *
