Quick question,

Will a 2-3 year old dura-ace double crankarm work as a replacement crankarm on a (2002) 105 triple? I want to keep the triple want to try out the differentlength of this crank arm. I can’t tell if it is compatible.

As long as the BB type is the same…yes.

From what I can tell that is the case. Thanks.

I would assume the spindle length of your BB would be different.

Generally

Doubles use: 109.5 mm

Triples use: 118 mm

But I won’t be changing the BB, right? I am going from triple to triple.

Thanks

Sorry. Read your post incorrectly. Though you were going from triple to double. You should be good to go.
