Weight is low for the strength and width
Easy to air up
Very stable at low pressures (28psi +)
Stayed true over 2years use

Weld is not pretty!
Needs to be dremelled around valve hole for rim strip to sit properly

These rims built up well on Hope Pro II hubs with Wheelsmith DB spokes. Roll well, strong, stayed true, minimal treakes of the spokes over time to keep them that way.
I noticed a few issues above that people have had getting regular tyres to set and seal. This is imho part of the challenge of using regular tyres on tubeless rims. I've been running tubeless for 4 years on 4 sets of wheels.
You do need the rim strip if you are running low pressures and want security against burping. An extra layer of tape under the rim strip does help with 'loose' tyres, both airing up and ensuring a good seat. Don't use loose tyres if you want security! I've been happy with Nevegals, Larsons, Minions (DH front single ply), but haven't been able to get specialized enduro or adrenalines to work (too loose). Paid $150 AUD each for these rims with rim strips. (aprox $130 USD), so they are not cheap but do a good job.

General appearance (once cheap stickers are removed), low weight (545g) for the 32mm width of the rim. Easy to get the tyre (tire?) to seat. I had no problems fitting Stan's Nylon spoke tape. Wide rim, gives a better tyre profile (I moved up from 23mm Mavic 317 rims).

Ugly weld area, a case for function over form. No eyelets. This was explained to me as follows. Normal rims have very thin material where the spoke holes are, so need eyelets. Stan's rim save weight in the bead area, so can use more material in the spoke area, and do not need eyelets. I suppose time will tell.

I have used these rims with 2 sets of tyres, in both cases with Stan's rim strips and latex, and I had no problems getting the tyres to seat and inflate.

The first set of tyres were Kenda Blue Groove/Nevegal 2.35 Stick-E's. These aired up easily, but as described in a previous review took 2 weeks of turning to finally seal. In my case it was the side walls (not the bead) of the tyres that caused the problem, and certainly not the rims.

The second set of tyres were Maxxis High Roller/ Minion DHR single ply 2.35 tires. Again, these aired up easily, and due to the better contruction (heavier side walls) they sealed almost immediately.

I believe that the key to getting these rims aired up is plenty of soap suds, and a decent floor pump. I use a Blackburn TP5 floor pump, which can get a 2.35 tyre to 40 PSI in only 10 strokes. The tyre seats at around 35 psi, with a loud twang.

I don't now if Stan's had problems with these rims, or whether they were not selling, but they appear to have disappeared off the Stan's website. They may have been replaced by the 28mm Flow rims at 470g.

I bought these on the basis of the width to weight ratio. No one else comes close. Most 28mm wide rims weigh the same or more.

mmmmm, it is black!

Everything, hard to get tyre on, off, impossible to seat tyre, weld is horrible.

Do not buy these, they are the biggest waste of money I have ever seen, there is a reason people use 819 or 823 rims, and these let you know why. They refuse to seat any tyre tubeless (all that seat on my 823's both tubeless and non tubeless). Don't watch the Stanz video and be convinced like me, have tried everything to get them to seat, but no joy. Oh well a waste of over $800 on set of wheels, I will know for next time.
Shame there is not a 0 chili setting or I would use it!

Almost as bad as a RF warranty.

Stays true. Looks good.

Not easily sealed when used as tubless.

After great success with Mavics UST wheelsets I decided to try these. With new Nevagals I had to keep flipping over and refilling through the valve stem for a month before they finally quit leaking. With used tires, forget about it. This is way to finicky for me. You can't tape the rim and run without the rim strip either because of the center bump (which doesn't seem to help with inflation).

I will say they have stayed true and work well with a tube. Rough single track and small drops have not caused problems. I haven't done any big drops with them so I can't say how they would hold up to freeriding.

Great black stealth look( after removing yellow stans sticker), Runs either tubeless, or standard tires. Extremely well rolling wheelset built by Richards Bicycles

Expensive, but you getwhat you pay for.

These rims are one of the lightest, but strongest rims I have ridden. When I first putthem on, I noticed an immediate increase in how the bike rolled. Really quick. They don't seem to flex in turns like some wheels I have ridden. This could be due to the quality of the wheel build by Richards Bicycles. I highly recommend thse to any one looking for great strength but light enough for long trail rides.

ZTR Flow rims (as there is not a catagory yet): Competitive weight, stiff, easy to inflate, more air volume, flatter profile (more tread on trail due to BSD - Bead Socket Design).

None so far.

Had the wheels built by Rbikes.com . I am very pleased with rims and overall wheel build. There is nothing more disappointing than having a new set that goes out of true after a few rides or is visited by the wheel fairies every time I brake hard and the spokes sound like a harp...

I am hardly a downhill racer, I ride more all mountain with little braking... I tend to use momentem rather than my lack of skill to overcome obsticles. My style (or lack there of) tends to be very hard on wheels. So far I have had none of the issues that others have had.

This review is for the new ZTR-FLOW rims.

Light build, tires weren't too hard to seal, but still *much* harder than Mavic UST rims.

Tried with Minion DHF and Kenda K-Rad. The K-Rads didn't seat at all, and had to be used with a tube. The minions (2.35 kevlar bead) seated ok, but took a lot of futzing around to get a decent seal. Despite what Stan says on his website, this setup was super easy to burp - small drop to off camber or any sort of hip landing will burp at least 1/3 of the time. Railing a berm I rolled the rear tire completely off the rim! Never did that in three years of DH racing using Mavic rims.

If you value your life, don't buy these rims, at least not for any sort of all mountain / freeride / DH riding. They seem to work ok commuting to work on flat pavement.

These rims are dangerous as they do not hold the tire on the rim properly. I have not even ridden these wheels hard yet and certainly won't after my latest experience of rolling the tire off the rim on a smooth berm. Would be real nervous with these rims on any sort of fast, rocky terrain.

Might be ok as hoola hoops or something, but certainly not on my bike. Waste of time and money.
