Another day with wheels (and so on).
Built the front wheel for Nomu Lab Wheel No. 6.
Evoluate hub 20H, CX-RAY outpoke radial lacing.
Separate from this, I did some work today on the rear wheel of Nomu Lab Wheel No. 6 that I handed to a customer just the other day—the chain dropped inside the low gear and damaged six inpokes in the porcupine direction, so I replaced all of them. Funny thing is, building this front wheel took less time than that repair job.
There's one thing customers ask me about fairly often, but I can't answer off the top of my head—and people seem surprised by that.
Actually, I can't instantly recall the finished weight of each Nomu Lab Wheel model.
I can instantly tell you the rim weight, of course, but a wheel is just an object spinning mass around its outer diameter, so all that matters to me is the rim weight and whether I managed to lace it stiff enough.
I write this from time to time, but that whole "front and rear wheels under 1,200g combined" thing is honestly a pretty useless metric.
(Though now that I think about it, you do need that to squeeze a complete bike down to 6.8kg on the nose.)
For this wheel, the only information that really matters is "the 310g rim wheel," and beyond that I just want to lace it as stiff as possible—and ideally stiffer than Reynolds UL32 or Shimano C24TU, which would be even better.
For example, Dura-Ace doesn't make a 20H front hub, but if it did and I laced with that, this front wheel would end up in the 500g range. That weight increase barely bothers the spinning mass of the wheel at all. Shimano hubs do hold up better to neglect and rough use than Tni, so the weight increase isn't necessarily a performance downgrade.
But today a customer asked me "How much does the Nomu Lab Wheel No. 6 front wheel weigh?" so I decided to measure it. Here's what I got.
I don't remember the wheel weight, but I can calculate it. Working backward from spoke specific gravity, my estimated spoke weight comes out to 93.88g for 20 spokes, so call it 94g. Hub 60g, nipples 7g, rim 310g—so the rough total comes to 471g. I can work it out pretty accurately, but without a calculator it takes time, so I usually don't bother.
