And there they are .. studs and nuts holding the sprocket on, not bolts.
My hub has bolts into threaded holes in the ally hub which are helicoiled as std.
Presumably this is to avoid thread wear in the soft ally hub.
The thing is, I recall contacting dymag to suggest that the helicoil inserts were not really long enough and didn't give enough thread engagement.
At my request they fitted longer ones (or doubled them up, I'm not sure which). There was plenty of room in the hub casting.
The only thing I can't remember for certain is whether this was on the sprocket side or the disc side .. or both.
Anyway, this was about 18 months ago.
Now that I've seen your wheels and, given the timescale needed for a design modification to filter through to production, I'm beginning to suspect that they may have changed to studs following my discussions with them.
Of course this is all conjecture .. I may be entirely wrong.
But it has aroused my curiosity.
I might give them a bell.
Maybe I'm due some royalties
