Favorite Ride: along Pacific Coast Hiway in So Cal
Bike Setup: LeMond Versaille (ultegra), Look 555 (ultegra), Scott Addict SL(Dura-Ace),
Summary: I bought a Scott Addict off eBay and my first set of Shimano Scandium wheels came with it. I never ridden tubeless wheels and I thought it was just the whole set up (Addict SL frame, Dura-Ace group). My first bike is a LeMond Versaille. It was a beginner carbon bike and it served me well. I picked up a Look 555 and it was light years ahead of the LeMond. However, The Scott Addict SL is in a completely different league. The Addict was just amazingly fast on flats, excellent on descents and climbs fantastic.
So I thought, 'Gee, I want a brand new Addict.' I went to the LBS and they gave me a fantastic price on a brand new 2008 Addict R2 with all Dura-Ace build but with Mavic Premium clincher wheels.
After 1 week, my bike came and I took it on my usual riding route which included a big hill. I was not able to keep up with my 2 buddies and the climb was difficult (but I did finish).
So I went back to LBS and asked to trade the Mavics in for a set of 2009 Scandium tubeless and guess what? These Shimano tubeless wheels made the difference! The whole bike came alive. The handling is fantastic, grip is excellent (95psi front, 100psi rear), up hill response to pedal stroke is instantaneous. Comparing, the clincher felt dead and slow; all the senses were muted.
Strengths: I just started cycling a year ago, so I don't know the correct term to describe it. The best I can do is 'magical'.
Weaknesses: I just started cycling a year ago, so I don't know the correct terms to describe it. The best I can do is 'expensive' (when bought brand new).

Favorite Ride: Down Canada Rd and Up Kings Mountain Rd
Bike Setup: 07 Bianchi 928 C2C full DA
Summary: These wheels were gifted to me by my parents (aka they paid for them). I am glad I did not pay the $825 out of my own pocket. They were ~250 grams (I have the exact numbers somewhere..) lighter than my 32h custom DT Swiss set up (DT R1.1+DT Onyx hubs+DT spokes).
About the WH-7850 SL:
These are beautifully made wheels that are true straight out of the box. The attention to detail is amazing... The rim has weight embedded in the rim across from the valve for balance. It came with a wheel magnet and there is a spoke both in the front and rear that has a small piece of plastic tape on it, I assume this is where the magnet can be snapped on. The hubs are smooth but they do make a 'weird' noise when freewheeling, also they don't seem to roll as long as my existing wheels, I suspect this has to do with me breaking them in.
About the Tubeless tires:
One of biggest reasons I opted for these wheels was to try out the tubeless tires. I hate mounting tires. I watched the video on notubes.com to see how tubeless tires should be mounted and then attempted to mount them. To my surprise they mounted much easier than normal tires, the deep center channel in the rim can be used quite effectively to mount the tires without the use of any tools. I tried to inflate the tires using an air compressor that can be plugged into the cigarette outlet in a car. The front tire sealed up nicely once I rubbed some soapy water along the bead, the rear tire refused to seal, it just wouldn't hold any air. After much frustration I decided to use a CO2 cartridge, that worked like a charm! Highly recommend using CO2 to seal the tires to the rim (they work exactly like car tires).
The ride:
I normally run my tires at 100/110 (front/rear), so I did that for my first ride and then gradually lowered the air pressure based on 'feel'. I currently run 80/90 and absolutely love the smoothness and grip with cornering.
I probably have about 500 miles on these wheels right now and to be honest, on the flats the wheels don't really seem that different, other than in cross winds, these are much more aerodynamic (you certainly feel the difference going from 32 to 16 in the front wheel). On climbs is where I was really surprised. These wheels are laterally very stiff... I expected that, however, what I did not expect was how they accelerate going up a climb. Going up a 2500ft climb in Nor Cal (Kings Mtn Rd) as you near the top the switchbacks get more painful because of the sudden increase in grade. I usually climb through the switchbacks out of saddle to leverage my body weight, doing the same on these wheels surprised me, the snap in the acceleration is something I've haven't experienced before.
Would I recommend these wheels? If you have $800 just sitting around, go for it. They are great. Otherwise, I don't think that it is the best bang for the buck, I would recommend custom wheels if you had to upgrade your wheelset. And choose a rim that doesn't have any spoke holes so you can easily convert them to use the tubeless tires. I do recommend the tubeless setup.
Strengths: The look awesome from the cockpit. I especially like the black rims and silver hubs. The accelerate well on climbs and with tubeless tires can be run at low pressures where smoothness and grip are amazing.
Weaknesses: price. Custom spokes (but this is a weakness on any good name brand wheelset in this price range)

Favorite Ride: Park Orchards, Warrandyte, Kangaroo Ground,
Bike Setup: 08 Cannondale Super Six, Dura Ace group, Cannondale (ie FSA) carbon cranks, Easton EC90 post, Easton EC70 bars, Fizik Aliante saddle. Very black.
Summary: I have had these wheels approx 6 months. They are pretty light, look good, and have stayed true. I really notice their benefits when accelerating on a climb.
Strengths: Extremely responsive to sudden accelerations. Good value (compared to Ksyrium SL with which I believe they are highly comparable).
Weaknesses: The rear bearings were a tiny bit tight, had them adjusted at the LBS, fine now. Very minor tweak performed on rear wheel true.

Bike Setup: giant team advance 2008 model with integrated seatpost. Dura ace all the way around. Changed out stock cassette from 12-25 to 12-27 for north georgia mountain rides.
Speedplay zeros, specialized alias (looking at Toupe)
Summary: The 7850's came on the Giant Team advance bike. The bike is Marvy ! The Wheels are stiff and fast. I have Mavik SSC on my other bike but these 7850's are faster, as stiff as the Maviks but the wind does not effect the 7850's like the maviks. (due to spoke width size) Could not be happier They are still true and rolling well. I do have tubes on these with Continental Force/ Attack tires. This is actually a lighter set up than tubeless on these wheels...
Strengths: fast, stiff and wind does not effect like maviks
Weaknesses: none yet

Favorite Ride: Wide shoulder, light traffic, and flat
Bike Setup: Windsor Kennet (aluminum frame, carbon seat stays and fork), all Ultegra group except Dura-Ace crank
Summary: I pulled the trigger on a set of these from ebay ($800 including two sets of tubeless tires). Some guy took a bit of a beating, to my good fortune. He threw in 2 sets of brand new tubeless tires.
The first thing I did was to throw them on my truing stand. Both were perfect. I "true" my own wheels and feel proud to get my cheap wheels and commuter wheels to less than a mm. Sometimes I just have to throw up my hands and admit, I just can't do any better. But these where absolutely perfect.
The next thing I did was put them on the bike for my first race of the season, a 36-mile circuit, half on asphalt concrete, the other half on chip seal, I would say very good roads.
The wheels roll noticeably better than any I have ever ridden before. But the point of these is the tubeless tires. Having never ridden tubulars, I can't compare to that. All I can say is they sure feel nice on that chip seal.
I didn't win the race, but I was on or near the front most of the way.
I'm pretty much a Shimano fan, so I expected near perfection.
Too many other high-tech features for me to list; see their ad.
Strengths: These wheels are so beautiful you will have second thoughts about using them in the out of doors and exposing them to the elements.
The wheels roll nicely and so far are perfectly true. They are so light they seem to jump with each pedal stroke.
The 7850 model has the spoke nipples at the rim, which is traditional. The previous tubeless model had the spoke nipples at the hub, which is not my favorite thing about Shimano wheels.
Titanium rear hub.
Weaknesses: Limited tire selection so far.
But the Hutchinsons seem to be great. Feel at least as nice as Michelin Pro2 Race's or Conti 4000s's.
Otherwise, I haven't noticed any weaknesses so far.
Similar Products Used: I've never had a set of wheels that are anywhere near to this class. I've had a lot of light, low-end throwaway wheels and 36-hole custom built commute and training wheels.
