So then when you made it back into a triple, you were setting it up as it had been originally, with the proper spindle for a triple already in place.
That's just a guess, but it seems like a probable scenario to me.
Old SR crank. 52/40
New SR Apex 52/47/36
Is this what is meant by the chain line?
The chain looks really straight from the small ring to the large sprocket.
I'm thinking it might be more plausible, that when the LBS replace the bb and spindle,
when ahead and replaced it with a longer spindle. Who would know, might even be better.
The UO10.
