It's completely illogical.

All of these have an interference fit, while the freehub body to cassette is a loose one.
Disc hub and drilled cogs FTW.

That's my plan :D

I'll be drilling some for some guys on other ssfg forums, so if anyone is interested, PM me.

With all this talk about splines, and Miche being the only ones to have made such a thing specifically for fixed, it would make sense that the experience people have had with the cog carrier would go a long way to settling this (aside from anyone who has had issues with their threads and the carrier.

From nearly everyone I've talked to who has used the cog carrier, I've heard that the splined do develop play. Some sooner than others. and I believe that it is a steel/steel interface. much stronger than al/steel
