Another day of wheelbuilding (and so on).

Built the Nomu Lab Wheel No. 5 using Shimano disc brake hubs.


Front wheel: HB-RS770 28H black semi-comp 46x14 cross lacing with spoke wrapping,



Rear wheel: FH-CX75 28H black semi-comp 46x14 JIS lacing with spoke wrapping,


with black spokes and silver nipples.
The customer's bike is a disc road bike, not a cyclocross bike.
The Nomu Lab Wheel No. 5 rim is almost the same weight (approximately 385g) as
Stans' Ironworks, but that's been discontinued, and even then the air pressure limit is only 3 psi, so
it can't be used on a road bike.
Their Grail can handle up to 9 psi, but the rim weighs 460g.
So this is essentially the lightest-class WO rim available, but
I'm currently running a Nomu Lab Wheel No. 1 rim (same width) on my cyclocross bike with
40C tires up front and 38C in the rear, so
of course 32C is no problem—meaning this can be used on a cyclocross bike too.
The unused brake zone might be a concern, but
there's no other rim out there that can be this light and still be this taut, so there's not much to be done about it.
