Strength:

Light weight, for intended AM/Trail use. Strong. Build up nice. White is nice.

Weakness:

If you don't plan ahead, standard valve stems are short and kinda hard to get to.

I've used these for a little over a year, all 4 seasons. Tires as thin as a true 1.9 and as wide as Kenda and Maxxis 2.3 large volume tires (fork won't take much bigger tire). Ridden heavy XC and some light DH, in a glacial region, so I've hit a few large rocks. These are, by far, the best rims I've used. I've run Bontrager, Mavic, Sun Ringle and Specialized, these are head and shoulders above those rims. I don't run tubeless. The wells are deep, which would make mounting a tubeless tire easy. I don't even know if they are tubeless, btw. I do buy 50mm (or so) valve stem tubes, they are the same price, just have to ask for them. Had to do a touch up true once after they were built and once about 6 months ago. I had a sound coming from the back wheel so I rebuilt the hub (Hope's are sooo nice) and found it wasn't the hub after a short ride. It was the spokes. I was able to get almost a full turn out of all of them. I had it in the truing stand and it was off by maybe 2mm! I had ridden our local hard packed rock filled trails, Kettle, a week earlier and since the spokes were uniformally loose, I can assume they were loose during the ride as well. Usually after a ride at that place, I either pinch flat or need to true the wheels. Every one of my previous rims have a flat spot from Kettle, usually during the first or second ride. I've ridden there 10+ times and have nothing to show for it. I'm about 250 lbs and run at least 40psi and ride a hardtail or 2. If you were to use these rims for DH, I would use them as a "race only" wheel set. I read about people using these for huge drops, they are only 545 grams, so I don't think they would last, imo. Get Spanks or DMR's. But if you want to replace your rims with something that will last a full season and then some, I've done 140+ rides, these are totally worth it. And I did get the white and yes they get dirty. A Mr Clean eraser spunge will bring them back and a coat of car wax will keep grease at bay.

Strength:

Strength, weight, durability....should I go on.

Weakness:

the matte white is a chore to keep clean...but it is a f mtb right.

I have close to 4 years on this rim with I9 doing a custom build to for me. Trued once. Period. I am a BBI trained tech. I raced bmx and dh for years but I don't case things or major huck. This have ridden 80% of Pisgah, Dupont, and even been thrown on my Dh bike for some random SE races. I have run them tubeless with Stans 25mm tape as well but I had to wrap twice. I run tubes 90% of the time and have had maybe 4 flats total in those years. mostly from poor tire pressure. This is a solid rim that is AM rated and it performs flawlessly in the class it is rated in

Strength:

strength to weight. spoke holes eyeletted. width.

Weakness:

rim has grooves to bite into tire sidewall and prevent rotation under low pressure.

I chose this rim because a few of my friends use them for AM/Dh. It is extra stiff for 545g. As a front this rim lasted just over 6 months. Having raced Dh, hit some 6 ft drops and 30 ft doubbles the DS28 seemed like just the right strength to weight for me, untill I bent it in half. 10ft to flat was too much. I suggest use for AM or light freeride not downhill. This rim did eat holes around the bead of my tire(-1 chili for overall)and it's one of the worst tacos i've seen(-1 overall) I picked it up %50 off, but for msrp you can get a stronger rim that wont shew your tires up(-1 for value) Good rim if you get a deal. I don't know how they last for Dh?

Strength:

Very strong and yet very light.

Weakness:

None

These are the lightest, strongest rims around. I use them on my dj/street bike and they stay true and round even with smaller tires at low psi.

Strength:

These are good rims! They are extremely stiff and because of the stiffness put less stress on individual spokes. They will not dent or ding very easily. The True Track does just that - keep the tire from moving. They've had no problems with the bead eating into the tire as I once read. I bought them because I like to use a very large front tire and these rims enable that.

Weakness:

The wheels don't lend well to a tubless conversion - I think because of the True Track. If you're okay with tubes - this is a winner. The white matt finish looks great when new, but next to impossible to keep clean - could use a gloss finish. The flat outter part of the bead intended to reduce pinch flats when using low pressure doesn't work with smaller tires (2.1)

If you're a freerider who's okay with tubes these are a great value. They'll hold a very large tire at low pressures very well, but not so good using low pressure on smaller size tires.
I weight 210 and ride very aggressive XC 4 times a week. I'll sometimes use a 2.1 Panaracer XC Fire Pro tire on the rear (a preference at home) and if not the proper pressure, it will pinch flat. I'm no pro or racer, and not nimble either. Where most may pick and choose their way through a rock garden, I'll plow through it at speed like a herd of elephants and let my suspension do the work.
I'd stick with these a little longer, but I want to go tubless and Stand's came out with the ZTR Arch in white. So I'm gonna order a set of those and have them laced in place if these Syncros.

To the designers at Syncos (if you read this): This is a great rim. Change the white to gloss and get rid of the True Track (so they can be converted to tubless). What ever you're doing to achieve ridity and metal hardness at this cost factor, don't change it.

Bottom line is these have an incredible stiffness to weight ratio. White matt finish is hard to clean. Not a good tubless conversion candidate. Very low price = great value!

Strength:

Very light, look good, tires mount easily.

Weakness:

These rims are soft and don't hold up to abuse.

I bought these for downhill use, which is likely not what they are intened for. The seem to dent and flatspot easily even running higher pressure. Also they don't seem to work well running tubeless with Stans strips. The beads don't hold the tires well and I get random unexplained flats. I've run tubeless for 3 years on various different rims, these are the first rims that I've had issues with.

They would be a great rim for all mountain use, but not much more than that.

Strength:

strong AND light, 545g, in the same ballpark as DT-Swiss 5.1D rims, oh, and they're strong

Weakness:

bead lock might hinder a tubeless conversion...

these rims are great. they work so well (also, the pro2 hubs are awesome) that I kept the wheels when I sold my previous bike and they are now on my Khyber.

I pinch flatted the rear tire at the bottom of Velocity at Mammoth, and had too much speed to slow down enough before the drop/step-down at the end of the trail. still went about 6 feet down off of the launch then rolled down the rest of the rocky landing and i got one flat spot about 1.5 cm long. i bottomed pretty hard too (still on my Jamis Dakar XLT back then). great rim.
