Hmm. It seems like either the specs are just wrong, or there is another attempt to redefine terms that have become misunderstood.
According to the specs this rim is both “single wall,” and “Box Section.” The term double wall was adopted to describe box section rims, and single wall rims can’t be box section. You could say that they are “channel section,” but that term would be new, and apparently nobody wants new terms.
Still, it is really cool that they are making it. The price seems very good as well. If I ever get around to building a fat uni I can’t see why this wouldn’t be my go to rim.
I finally got my Nimbus Dominator 26" fat rim built up. Thanks to Killian for helping build the wheel and putting up with my orange spoke fiasco.
I used a Surly Bud because it’s the best darn 4.8 unicycle tire there is. However it’s not the best for tubeless.
For the first try I set everything up split tube and the Bud’s bead was weeping more than normal.
So for the next try I cut up an old 36" tube into two 1/4" strips. I ran one layer of orange 3M tape for the cutouts then one layer of Tyvek tape to cover the sticky side. Surly’s rim strip is out of stock but the orange tape looks pretty good. Then to adhere the rubber I put a wrap of double sided scotch tape on both bead shelves, and applied the 1/4" rubber strips. I added the spit tube and sealant and it aired up very easy. The only difference is this time I had zero leaks. The next morning I had one little drip but the strips seemed to have worked.
I took it out this morning with Killian and it rocks! It rolls over everything, has very little autosteer and just makes smile. Anyone who’s interested in a 4.8 tire, or someone who has struggled with other fat 4.8+ tires(2XL). You need give the Bud a try. I’ll probably be selling my 29+ Rabbit Hole/Knard wheelset…
They are powder coated, so they are thicker than normal spokes. They’ll fit through the spoke holes of the hub flanges, but when you try to bend it to lace the spoke, it binds up, and eventually scratches off the powder coat at the elbow.
Not impossible to do, but it’s easier to just use SS or black.
And I forgot to second Fugsworth’s suggestion on the Surly Bud. I have no idea why everyone is on a Lou, but the Bud is amazing.
It is a pain when they fit the hub so tight, but if you lace the whole hub at once you can build without having to bend any of the spokes. You do have to be careful not to scratch the paint off when they go through the holes, but once that part’s done it’s smooth sailing. It also laces up much quicker, about 10 minutes to lace 36 spokes.
Next time you build shoot me a PM and I’ll walk you through it. It’s not difficult once you understand the basics. And at this point I don’t think there’s any question about your understanding of the basics.
