1990 Schwinn Voyageur picked up this past spring had a Sakae XCE crank, with a absolutely useless BB. BB spindle had posts like the ones for the XCE and XCM in hazelnutguy's reply here:
Measuring excluding the bolt post things yielded 125 mm and so used a 125 BB-UN55 had laying around. Chainline's perfect for the triple. Have no experience with a double.
From hazyguy's data sheet, the XCM is takes a BB spindle 2mm or so shorter then the XCE, so perhaps you can extrapolate to like 122.5 for the triple and 115 for the double?
Good luck!
Thanks. The N-3T spindle hazetguy's doc references is 126mm in length, per the Indian Standards Organization document Sheldon Brown references somewhere on his website (it's in PDF, and I have a copy stored locally). I think I've located a source for one of those and have it bookmarked.
