Strong, smooth and light. Cost if you can get a deal like I did.

Not very aero

These wheels are light and stiff. They spin about the same as my OP/Ultegras but they spin up faster. Accelerating out of turns with these wheels is far easier and faster. They ride very well also, they aren't very deep but they roll well on the flats. They fly up hills no flexing and I weigh in at 280 lbs. I can stand and pound away. I am very impressed.

Very impressed with the build quality (typical Shimano), but I am most impressed with their stiffness. I have put a good pounding on the wheels over 1k miles and so far so good. A very solid choice for daily rides.

My only complaint is that they did not come properly trued, as others have stated. I have also swapped out the quick release for a lighter set.

I received a large gift card to REI and figured I would give these a try. Initially I was looking for the Dura Ace 7850, but for the money I couldn't pass these up. After having ridden these for 1k miles I am very happy with my purchase. These are a great all around wheelset and would recommend them to anyone looking for a great all around wheeelset. I'm currently riding a Blue RC4 with Sram Red and even with these wheels my bike is sub 16 lbs. I haven't weighted them yet, but would expect them to be close to the advertised weight.

Stiff enough, fast and relatively light

Do not turn heads

I an not a racer but I do fast group rides in rather hilly terrain. Before I purchased RS-80 I used Mavic Axium (heavy,but otherwise excellent) and Aerohead
Pro (very light but otherwise crappy). RS-80 are al lI wanted. Stiff but comfortable, good acceleration and light enough for climbing. They stayed true for 2000k and seem to be rather durecble

Superb ride quality, long rides are non fatiguing.
Excellent all round performance.
Definitely superior all round than Ksyrium SLs
Unbeatable at price

none really, but they could have pretensioned the spokes a little better
have not had any truing problems since initial touchup

I was so impressed with my previously purchased Shimano WH 7850 50mm deep aero wheels that I decided to purchase another Shimao composite wheel as my non-aero, general riding and windy condition wheels. The RS80s are certainly excellent, with the same Dura Ace rims as the C24s. Build quality is not quite as perfect as the Dura Ace versions and I needed to do a quick touch up of the rear wheel true. However, once done, onto riding. These wheels are great all rounders. One standout is the superb ride quality. These wheels really do soak up road buzz yet retain the qualities of a race level wheel - stiff (but not as stiff as the 50mm rims), very quick acceleration and great climbing. Braking surface is top level. There is a wear indicator on the rim.
