If this is the newer splined design then....Chicago_Steve

Dura Ace BB-7700
Ultegra BB-6500
105 BB-5500

They all use the same spline pattern. FWIW... I use the 118.5mm triple version of the BB-6500 with my Kelly Knobby X when I was running these cranks. The shorter 109.5mm double version had the chainrings hitting the stays...
thanks, and the reason I ask is...FTMD

I had a bad chainline on my Voodoo cx bike. In the big ring, any gear combo middle half down on the cassette produced a dramatic angle on the chain, which just shouldn't be there.

Pulled it out and tried to install a longer bb of the same width, but the splines didn't match up. I'm thinking it was an xt or lx bb that I had lying around, and I think those splines do differ slightly.

Your comment about your Kelly does help clear up my chainline issue tho.......thanks.

I've got XT on my mountain bike and Ultegra on my CX bike and the splines are deeper on the MTB stuff... (although I think the spline pattern is the same on ISIS stuff)...
