Problems installing a GXP crankset

Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Problems installing a GXP crankset

Hopefully Iím doing something stupid and itís an easy fix but Iím having one hell of a time. I have a SRAM S900 crankset. Up until recently it had a Quarq spider on it. The Quarq died and I purchased a new one, Quarq removed the spider and sent the crank arms back to me.

So, I purchased a new Origin 8 spider and installed it on the crank arms. Now when I go to install it Iím having a problem with rubbing at the bottom bracket. Iíve tried several different combinations of spacers and the wavy washer.

Any thoughts?

I just removed the crankset off of one of my road bikes to see if it would install without any issues. It works perfect.

shouldn't the silver part of the spider be flush with the bolts?

Figured out that the crank cutout (indention) on the outside of the crank wasnít wide enough for the crank arm. I did some quick grinding and it works like a charm. Iíll smooth it out and paint it later on.

Just to clarify, this was an issue with the origin8 spider? And you ground it to make room for the crankarm to sit more inboard?
