Strengths: Lightweight, good looking, hold their true even when bashing through rock gardens
Weaknesses: Finding the valve stem can be tricky if you need to replace one.
I ride mostly x-country trails in UT, but get into rocks often (think porcupine rim trail, Magnificent 7 trail, Amasa Back trail, etc in Utah and you'll get the picture). These wheels came on a 2008 Pivot Mach 4 that I purchased with the XT setup and they ride great and hold their true. I've ruined lesser wheels on the same trails. They are not as smooth as some non-disc XTR/Mavic 717 that I have on another bike, but meet my needs between lightweight, low rolling resistance, price, and ability to take the occasional abuse. I would not recommend these wheels on a downhill bike - but then again, they are not intended for jumping off of 4 ft. drops. I weigh about 180 and ride very aggressively. I would buy these again in a nano second. I ride a between 1,000 and 1,500 miles per year and have yet to service these wheels which have > 3K miles on them. I ride tubeless with about 28 lbs pressure.
Strengths: Great compromise between light and strong, stiff, top notch build quality, works well with center lock/6 bolt Shimano adapters, UST works perfectly even with non-UST tires, got a great deal on the set.
Weaknesses: I wish it had a 10 mm rear axle instead of the QR, center lock requires adapters for 6 bolt rotors.
I bought these wheels hoping to get a strong "all mountain" wheel set but still be able to save some weight on the bike. So far these wheels have been great, they feel solid and stiff while riding them hard and at about 2000 grams a pair they roll fast too. I set them up with tubeless Nevegals and it's the perfect set up for me. I just hope they hold up for a few seasons.

Strengths: Great stiffness hold tubeless-ready tires very well at low pressures.
Weaknesses: Spoke tightening counter-intuitive, should be delivered with two spoke keys.
Work great even After + 1000 KM in very nasty muddy conditions and heat with my 96 kg, but no real downhill drops. Back wheel went out of true fairly quickly, but this is the usual with all the wheels I ever tried due to my weight.
Love center lock.
Very good price/quality as I bought them.

Strengths: Fairly Light , looks good , UST .
Weaknesses: Axel , cone bearing adjustment is suprising hard on the rear , after racing on my hardtail over blocked trails I notice the bearing slops radially, the hub itself is knocked out not the cone, Also the freewheel has failed after 3000km.
If you cruise around forest trails and dont go like hell down hills then you will be happy with these , if you are a serious cross country marathon rider don't take them unless you are prepared to throw them away each season.
Spares are expensive and here in Germany the hub is not available. If you are down hill or freerider steer away from these , they are not for you.
Similar Products Used: Mavic crossride , cheaper , use industrial bearing , not adjustable , are slightly heavier but do have aero spokes. so uphill slower downhill faster and safer And appear after 2000 km to be stiffer and sturdier.
Bike Setup: I use a hardtail , maybe people using rear suspension will not damage the bearing like I do on blocked trails with only the front wheel under proper control.

Weaknesses: Freehub - Do not buy!!!
Do not buy these wheels. MH775 rear hubs / freehub is garbage. Went through 2 freehubs in a years time. Freehub body has internal issues. Pawls lock up and/or do not engage. Spent time and money replacing 1st freehub body, only to have it fail the same exact way within 6 months.

Strengths: Sealed already for tubeless
Weaknesses: Spokes, hubs, etc.
After a little over 2 years and moderate riding I'm on my 3rd free hub internals. 2nd failure I almost wrecked in a rock garder at about 20-25mph because rear wheel internals fail and lock up. Dangerous wheels unless you only ride XC. But then they're heavey and expensive for XC. 60 each time for new internals. LBS said these fail alot and recommended hope or kings. YAY spent 600 and now I have to spend another 800 for custom wheels!!!
If you want good wheels that wont fail every 6-9 mo. get a custom built wheel. I will be fighting this recent charge with Shimano.

Strengths: Lightweight, looks soooo cool.
Weaknesses: Rear hub WTF?
Bought these wheels 1 yr ago and they have been awesome. Then after a ride last weekend I noticed something was wrong. The axle cones and bearings are toast. I looked at my receipt and of course it's just over 1 yr. Now I have used XT hubs since I started riding back in 91 and have never had a hub die on me like that. Then I read the reviews here and obviously something is wrong with these hubs. Now I have to wait and see what/if Shimano is going to do about it. All this right before a trip. Not cool.

Strengths: Good quality rim, paint, and hub seals (only).
Weaknesses: Freehub, Front Hub, Front Brake Center Lock, Nipples seem soft. Red anodize does not go with every bike.
Hubs are not worth the money. Suggest buying a 28mm cone wrench for the front hub adjustments. Center Lock is good on my Saint wheels, but the same quality was missed with my XT wheels. Front rotor has some play in it, but it does not affect braking. Free hub broke in less than a year, and was replaced under warranty. Shimano needs step it up in their wheel bearing and freehub manufacturing. They are using old technology, and are getting passed by the competition in the terms of innovation and quality. I love the Shimano rims; they seem to have a good quality feel and strength. These rims are some of the best hoops out there and are what I aspect from a large corporation. I would consider using a different brand of hubs with rims. If Shimano put the same time and engineering into the hubs as they did the rims these wheels would be unmatched at the current price. 4 "Chili’s" given for the "Overall Rating" because the wheels are great when working at 100%, and the quality of the rims. 1 "Chili" for the "Value Rating" because I have seen lesser wheels have less problems. These wheels are marketed for “All Mountain” use, and they should go the distance. Bottom line is I will not buy another Shimano hub until they reinvent the wheel.

Strengths: quick and stiff and light like all similar products(of same category)
Weaknesses: free hub,but have u ever seen a free hub not fail?since I work in a shop,I've seen all types of wheel sets.Originaly I wanted Mavics but didn't want to service them often.(know them too well).And shimano products are available easily.Just order spokes and a freehub in advance because you will need these parts eventually.like any other wheelset.By the way shimano parts are cheaper(less Expensive)than mavic and all the rest.I'm on my second freehub and shimano have warrantied them cause they have the best warranty on the market.
Allways have a second set off wheels if youre gonna ride a set of racing wheel for everyday riding.Guess some peoples aren't as lucky or it's always the same one's who have issues. LOL
Strengths: This review is for the Enduro M776 wheelset. 21mm internal rim width and 20mm front axle.
Light, strong, the right width rim for hard riding, great bearings.
Weaknesses: I have had zero problems.
I have the WH-M776: wider rim and 20mm front axle compared to the 775. I really like this wheelset, I'd buy it again.
I wanted tubeless and at least a 21mm internal rim width. I got rid of my old Mavic ex823 rims because they were just too heavy for trail riding. There just aren't many options out there in this category. Mavix CrossMax are supposed to be good, but they're way too expensive. These Shimano's fit the bill, and the hubs are easily rebuildable. I came from King Hubs, and if you ride aggressive, Kings just take too much maintenance (and are a ripoff).
I also think these wheels roll fairly light. Good bearings, and the straight-pull steel spokes don't have 75 grams of extra nipples at the rim like Mavix 729 or 823 rims. Keep the weight at the hubs and your bike will accelerate faster.
The engagement is plenty fast for me on these newer Shimano hubs (36 pt, I think). I came from King hubs, which I hated. Noisy and they required constant maintenance. Also, you can rebuild the Shimano's without expensive tools - you just need a 14mm allen key, which isn't expensive. The seals on these new hubs are much better than old Shimano, even riding all winter in wet Seattle.
I've heard issues with the freehub, but I think Shimano fixed the issues. I haven't had a problem with them. I also know Shimano is really good on warranty, at least here locally.
Strengths: light and strong for all mountain riding
Value for money
The common problem.The freehub collapsed after 3 months. Shimano fix it free since then no problems And now after about 11 months the front whell has a little move but the mechanic at the bike shop fix it in 5 minutes
I think generly that are good all mountain wheels. OK is very bad for a 450euro shimano whellset have that problem but if i forget that everything are great

Strengths: Light weight. Quick engagement. Hubs spin freely. True UST without rim strip.
Weaknesses: Reliability. Came out of true quickly. Spoke broke just riding along (on the National trail). Free hub made loud crunching sound while climbing and now intermittently locks solid, feeding the forward when I stop pedaling.
Not quite ready for the real world.
These wheels might work for a lighter or weaker rider than me (at 195 lbs) or on trails less rocky or steep than those here in Arizona.
The wheels were recommended to me by the bike shop after I described the type of riding I do -- mostly cross country riding with the occasional foray up to the more gnarly trails. These seemed like a good deal at the time, but every other ride something seems to happen and as a result I've used my old wheels more than half the time.
Thought that the couple things i saw about the freehub "wouldnt happen to me" as they usually are very limited cases. WRONG. More i looked around after the failure turning my bike into a fixie, the more reports i saw outside of this page. Waiting for replacement...may just get a refund and go with saomething else. Shame, i really liked these wheels for the first hour i got to ride on them (yes, failed after 1 hour!). I have a hard time rating this because without the failure id give 4.5 stars (would like them a little lighter) but i cant believe this crap.
Is the freehub supposed to have a smidge of play? Reason why I ask is today I went out and noticed underload I get what feels like clicking and random slippage. I saw the Shimano manual and it says I need a 14mm allen to adjust the freehub, which I don't have, but will get if I do need to tighten th ... Read More »
