Hi Slugwash,
Likewise done some calculations. I used EDD Spoke Calculator Came up with right flange diameter; 52 (centre top hole to bottom centre hole), left flange diameter 58mm.
Centre 2 right 15mm, Centre 2 left 40mm, spoke hole diameter 2.6mm.
With a Mavid 721 Rim that gave me a left hand spoke length of 259.3 and a right hand spoke length of 257.6.
I ordered 32 halo PG spokes from Winstaleys for £8, will be building the wheel up on Tuesday.
This was for the 32h, Chrome finish hub. And yes very similar to a spindr but different in that the freehub has no allen key slot amongst a few other things, but essentially a very very similar hub.
Sure it’ll build up nicely into a cheap wheel (will come in at £33 for a new hub, new spokes, used Mavic 721 Rim!)
