ISIS and octalink compatability

[wardie2000]

Hi,

This may be a bit of a basic question but i need to ask it.

Are ISIS and shimano octalink bottom brackets compatible?

If i was buying a chainset that said it needed octalink could i in fact use an ISIS bb?

Thanks

To elaborate just a bit, the Octolink axle has 8 splines, and the ISIS has 10. As a result, an ISIS BB axle won't fit an Octolink crank arm. Octolink is the Shimano proprietary design, while ISIS is an open industry standard that any aftermarket manufacturer can use.
