wouldnt it be better to have a solid block with the disc bolt pattern
It's too far from the main wheel body to blend, and the air is already fucked by the chain where the sprocket mounts. A plain disc would be simpler to machine, but I like pretty things 🙂 On a CNC it's not much effort to do the shaping, obviously if you were doing it on manual machines you wouldn't bother.
What diameter are the pins (and the holes for the pins)?

5.00mm pins, 4.99mm holes 🙂
