I have some M752 XT cranks and a ES25 BB are these compatible?
I seem to have missed the Octalink years completely during my MTB life.

Thanks

Hmm, still not sure?
The XT one I have isn't listed on that list.
I have both already, which I am selling, I'm just not stir whether to sell them together or separate!

Out in a pub garden at the moment, but Sheldon is your friend. They are different enough not be interchangeable.

Do they fit together?

Yes, but it didn't fit all the way onto the BB, which is what was worrying me. I think this is because the first Octalink splined area wasn't as long as this one.

The main problem is that V2 splines are around 0.3mm wider than V1. Which means that at the pedal end, you'll get around an inch of slippage, causing irritation to the rider and destruction to the cranks.

Ask me how I know this. :facepalm:
