M900 and Ringle hub issue

[LeeDevelopment]

Hi

After several years lost in the wilderness I'm finally getting my retro steed put together however I have come to a stumbling block...... my M900 cassette won't fit on the Ringle Super-8 rear hub, and yes I have lined the slots up correctly. Am I missing something here?

Re:

All the ones I have fit fine, can you post a pic of the problem

Does the cassette go on at all, even a little way ?

Re:

Nick has come to my rescue, I just need to file the cassette's splines down a smidge... main body has now been fitted, just working on the outer rings as I type
