Another wheel day (abbreviated hereafter).
A customer handed me a Chris King BOOST-spec ISO front hub
that had been converted to a 120mm-width fixed-gear rear hub.
The CCB (Chinese Cycle Brand) company makes a conversion kit like this.
If you're interested, try searching for "CCB-001".
The kit includes a thick-tooth sprocket
designed for six-hole disc rotor mounting.
Rather than using nuts mounted on the hub axle for frame attachment,
this design uses bolts on the frame-side portion.
White Industries and Fillwood also make fixed-gear rear hubs with
this mounting method, and from what I know,
there have been cases of bolt deformation on White hubs,
so I'm not particularly fond of this approach.
I do understand that when using a converter-style system
to fill a thru-axle hole, this was the only option.
All built.
The rim is a Pacentti Blurbe,
32-hole, fully-competed Italian-laced (all-radial).
If this were a disc brake front wheel,
I would have done asymmetric lacing (64-46 pattern),
but this time I had various thoughts and decided against it.
The customer's request was just silver spokes with round-section spokes
(aero profile spokes are not acceptable), with everything else left to me.
As for lacing pattern, they said either way is fine,
but I'll probably end up lacing the non-sprocket side.
The hub-contact face of the dedicated sprocket
has a relief machined to match the ISO hub's rotor mounting seat shape.
↑This is what it looks like with the sprocket installed
