The Shimano RS80 wheels give you the effect of carbon, however beneath is an alloy rim, that makes it better for braking and general durability, and Shimano suggest the mixture of the two materials results in a light, firm and comfortable wheel. This wheelset uses totally the same patented Carbon/alloy rim bonding process that you get on the Dura-Ace 7850 wheels, although Shimano use a thinner Aluminium for the fundamental design of the rim, and then stick on a Carbon outer seam. 16 bladed steel spokes anchor the rims to Ultegra level hubs, which are understated in looks, fluid and well sealed. The one slight obstacle is the Aluminum nipples, that are too easy to round off if you have to carry out any fettling. On the other hand,during most of the testing miles that have been done, this wasn't necessary. The Shimano RS80 is a light wheelset for under ?400, a lot lighter than the Gipiemme Tecno 1.55 lights and the Fulcrum Racing 3s that have established the benchmark ?400 wheel for a while, in terms of all round effectiveness. They weren't as competent in the stiffness test, when related to other wheels in the comparable price bracket. The regular test is to apply a lateral effort to the rim and measure the bending, and the RS80's 5mm deflection for 15kg load is higher than both the Gipiemme (4mm) and the Fulcrum (3mm). By and large this gives you a good idea of how the wheel will act, stiffness-wise, out on the road, hence I was expecting noticeable bend and brake rub under effort. It didn't happen for all that - the RS80s were very well behaved nearly all of the time. I could get them to touch the blocks if I actually tried, nevertheless that happens with nearly all wheels to be fair. They're not as firm as a few of the competition, yet they're stiff enough, and a fair amount lighter for the same money. If you're an ordinary weight rider you doubtless wouldn't detect the contrast in flex. Where you do gain however, is in the comfort. The RS80 definately gives you a comfortable ride, since it's relying on the Carbon in the rim to keep things rigid, it has a fairly shallow profile, and this translates into a fluid ride, even on poor quality tarmac with the tyres pumped up to the max. With the tyres at regular pressure they work very well for longer rides, the light weight making them quick ascending and the compliance giving them a good feel on the flats and the downs. In general, the Shimano RS80 is a well proposed, comfortable and good looking wheelset. The Carbon layer is thin, on the other hand it does seem to create a difference to the ride, and the wheels are light and perform well for the money. Cutting rotating weight could make a sizable difference to performance, yet if you're looking to pay out around ?400 on some new wheels, then the RS80s are a reliable place to begin.
