I've got an older set of ST 6400 Shimano STI levers. Does anyone know if these can handle a triple or how I can determine if they can handle a triple (short of mounting and setting them up)?
They can't.Andy M-S

Shimano didn't make a triple in Ultegra/600 until it went 9-speed. 105sc is 6400's highest contemporary with triple capability, and only then on specific triple-compatible levers.

There used to be a device called a "gizmo" that plugged into 6400 levers that would allow you to throw an extra lever to shift into the granny, but I don't know where you'd get one these days...
