Bottom Bracket Question

I posted the following question on the C&V page. Thought it might be more appropriate here:

I'm rebuilding an 80's Giant 12 speed road bike and plan on replacing the stock components with Shimano 600 EX Abaresque pieces I have acquired over the past year. The BB spindle I removed from the bike is 113MM in length. The several "Abaresque" BB spindles that I've seen on various web sites, including
e-Bay, have all been 116MM in length.

My question is, will my 113MM spindle work with the Abaresque cranks or will I need to find a spindle that is 116MM long?

You have nothing to lose by trying it.

If it works, yay!

If not, you just need to find the proper spindle.

The design of the crank itself is one of the most significant factors in determining the spindle length that you need. Never-the-less, 3mm difference is roughly about 1 1/2 mm per side. That's not very much. There's a good chance that the shorter spindle length will work without your chainring rubbing the chain stay or creating chain line problems.

If it was my bike and I already had the parts I'd definitely put them together and see how they work. If I was buying new parts I'd hold out for a 116 mm spindle.

Thanks, that one was a brain twister
This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
