Another day of wheel building (and so on).
I've been holding onto a front wheel built with a 1-45 rim that a customer left with me.
For nine months.
Before that, I was waiting for CX-Sprint spokes to come back in stock,
so I couldn't build the next wheel.
To be precise, when I took this wheel in,
we actually had CX-Sprint spokes in inventory,
but as I was building wheels in order from previous orders,
by the time it was this wheel's turn, we'd run out of stock.
PowerTap front hub, 20H
Black CX-RAY spokes, radial lacing.
Since I'm not building a rear wheel with a PowerTap hub,
it seems unlikely they'd use just a PowerTap front hub,
so maybe the 24H rim I took in the other day
was built on a PowerTap rear hub.
The rim's serial number was in the 100,000 range (six digits), on the younger side,
so it could have been an EDGE brand rather than ENVE,
but I can definitively say this rim is ENVE brand.
Unlike the 24H rim from the other day, which had its sticker completely peeled off
this rim still had
an ENVE sticker remaining around the valve hole.
Just like the 24H rim, again there was
heat damage marks, but only
next to the spoke hole cover on the opposite side of the valve hole
You might say it's just a coincidence,
but
it really only appears in this spot.
I was able to build the next wheel.
Novatec D791-style hub, 20H
All black CX-Sprint spokes, 44-spoke reverse Italian lacing.
I'll do the spoke threading later.
Though it's a hub with equal-diameter flanges on both sides,
it has larger offset than a single-sided fixed gear rear hub,
and when doing equal-diameter symmetric lacing on both sides, the tension
on the non-rotor side clearly became lower.
When I researched the spoke trajectories in true tangential lacing for 6-spoke per side on a 20H hub,
even with this large flange, the reverse-head spokes overlapped the radial trajectories,
so I gave up on 44-spoke lacing.
The reason I didn't go with half CX-Sprint
(didn't use CX-RAY on the rotor side)
is that I had various thoughts about it,
but I decided to go all CX-Sprint, thinking that if both sides need threading, why not just do it
(looks like only one side will need threading).
I'm building the rear wheel with silver spokes on a rim-brake setup,
and the front wheel with black spokes on a disc-brake setup,
which obviously are going on different bikes.
If it was just the rear wheel, it would be semi-competition lacing, so I could have built it earlier,
but I was planning to build front and rear together once the CX-Sprint arrived.
I never expected the restocking to take this long.
As for this 20H front wheel, building it all with CX-RAY
would be, even with threading both sides,
(though the wheel might still be usable)
questionable from a stiffness standpoint.
Regarding the front hub:
It's definitely Novatec, but it's an unmarked hub.
It's almost the same as the D791, but the critical difference is
it's not a high-low flange setup.
For details (→here).
In that linked post, I also did a trial build of 6-spoke lacing on a 20H hub using the small flange side of a D791,
but even with this hub having a larger flange than that,
I got nearly identical results and it didn't work.
