Nomu Lab Wheel No. 3 is finished!
As promised, it's the rear wheel for the Tni Aero 80.
I was writing a long post up until just now, so I couldn't get this up yesterday.
The rim weight measured 529g.
The customer order from the other day was built with a 24H rear rim, but this one is 20H.
Technically it's for the front, but if it works out, using it on the rear is possible.
The reverse won't work though. Because we can't do a 46-spoke lace pattern and with the small number of holes at 20H,
I built the freewheel side with DT Champion 2.0mm plain spokes,
and the non-freewheel side with Sapim CX 2.0-(1.3-2.8)-2.0mm aero spokes,
aiming for minimal spoke deformation (= stiffness).
With a 529g rim, there's no point chasing spoke lightness—it's all about stiffness, stiffness!
That's what I thought, so I built it as tight as it gets.
I wasn't sure about lacing it, but when I did
things got crazy.
The deformation when gripping the spoke crossing points is almost zero on both sides.
It's turned into something like a disc wheel with side holes.
I'm imagining someone running matching rim-depth tubular wheels all-around switching to this rear wheel to enter flat-terrain specialist, ultra-stiff hammer-it mode.
Last time I built a 24H Sapim CX-RAY version at 902g,
but this time with four fewer spokes, it came to 916g.
If it were 24H, I would've used CX-RAY on the non-freewheel side.
As for the price you're curious about,
I mentioned Tni off-the-shelf wheels at 68,250 yen,
and the same spec built by me at 56,000 yen.
Those are 24H, but Nomu Lab Wheel No. 3 is 20H and
the spokes I'm using have different pricing, so I've set it at 49,000 yen!
At 49,000 yen, I'm aiming for the ultimate aero rear wheel.
