They were easy to set up tubeless, with either UST or normal tires, and popped up without any issue. Their Velotape tubeless system worked well, and I had no issues getting my usual assortment of tires to bead up on the rims. Some tires may require some sealant to hold air, but I use sealant with all my tubeless systems, so it was a moot point. I had more luck with tires that have a stout sidewalls, then floppy ones. After many months of use, I noticed the Velotape was starting to pull up in a couple of areas, although it wasn’t leaking, but my prodigious tire swap outs greatly exacerbated the issue.
I have been riding the Velocity P35 wheelset since mid spring, and I must say the rims are monstrously wide. It took me quite a few rides to get used to the stability and rigidity that they offer, and until you have ridden a rim this wide, it’s hard to understand the feeling they imbue. The rims let a tire flare out wide, giving a larger footprint, and allowing lower air pressure, all which give excellent traction, control and comfort. It may slightly alter the characteristics of a tire, since the tires sit out wider, and their corresponding profile is changed, and I found that fatter tires seem to work better than narrow ones. The rim profile along with the width, gives excellent lateral stiffness without much of a weight penalty.
I bashed these beasts through any terrain that I could toss them at, and they just stayed on line. I tossed them over sideways, torqued them hard, plowed them through rock gardens and smashed them into square ledges, and it did nothing impede them. You can pretty much bowl your way over anything, without any hesitance nor flex (2.0/1.8 spokes help). The stable and wide platform does mean it takes an extra touch of effort to roll them over, but it’s not much in the grand scheme of things. I did notice that they don’t accelerate very well, but when you can drive straight into anything it doesn’t seem to matter, and the monstrous tractor like traction certainly offers a more than a fair advantage. The Velocity hubs are somewhat primitive and a tad heavy, but have so far proven to be pretty stout and smooth, and I didn’t have any issues with the bearings nor pawls.

I noticed the other day, that on some technical terrain, where I needed to make a laser like steering adjustment, that the rims were slow to respond, making it more difficult to choose a precise line. I have ridden other wide rims that have slightly better steering, but there seems to be some other synergy going on (rim shape, spokes, hubs, ?) that makes it more anomalous. Fortunately, you can plow your way through whichever line you are left with, but it did make for some awkward transitions. They are very stable and want to stay in an upright position, and they take some initiative to muster them over on their side, but once there, they rail like crazy, and the width allows you to plunge them into berms to your heart content.
The wheel build has been bombproof, and the spoke tension and rim’s true have stayed the same the entire test period. I do wish the front hub had conversion adapters, so that it could be used with 9mm, 15mm or 20mm forks. The rim’s are painted, in contrast to the usual anodization, and I have found they’re getting chewed up and scratched quite easily. In daylight conditions, you can also see some minor painting imperfections (not a big deal).
