Lets discuss in brief about Fulcrum

Toyota has Scion, Honda has Acura, Nissan has Infiniti, and Campagnolo has Fulcrum. That's right folks, Fulcrum is a division of Campy. Why? Why not! If you had a cycling company and you knew how to make a superior set of wheels, but you also knew the riders were playing matchy match with their components most likely wouldn't put Campy wheels on a primarily Shimano bike, wouldn't you make a new company? We would! So if you were wondering how Fulcrum came up from nowhere and got worldwide attention on the pro circuit, it's because Campy used their connections to get up and running, and into the heat of the race. Yes sir, that's why the 2004 and 2005 pro teams actually used the Fulcrum wheels without years of being on the market. Pretty smart move if you ask us.
The launch of Fulcrum in July of 2004 was a testimony of passion for the sport of cycling. At the front of the company were three aerospace engineers who had applied their specialized knowledge of aerospace technology to the advancement of their favorite sport. Since the beginning, Fulcrum Wheels have proven their superiority on the road. They are designed and developed with underlying elements of Campagnolo, technological advancements of the aerospace industry and they have a pleasantly youthful Fulcrum twist.
With revolutionary concepts in wheel development and design, Fulcrum Wheels boast a perfectly balance wheel. To get that perfect balance they have patents! That's why there are trademarks all over this article. Fulcrum was big on trademarks and patents like Dynamic BalanceTM, 2:1 Two-to-oneTM, and the MoMagTM system.
When you push your pedals, the rotational force on the sprocket produces slack in the freewheel spokes and a loss of rim tension. This results in unwanted flex of the whole wheel and an inevitable loss of energy. Fulcrum has solved this common cycling dilemma with its 2:1 Two-to-One?Spoke Ratio system. The 2:1 Two-to-One?system supports the Dynamic BalanceTM by doubling the spokes in the critical areas. The Dynamic BalanceTM system boasts flawlessly balanced dynamics of rotation, with the credit given to the careful distribution of the rotating masses. The MoMagTM system supports the other two quite well. It actually stemmed from Campy. The MoMagTM system feeds each nipple into the rim through the valve hole, the process is guided perfectly into place with a magnet. Thus the Mag in the name MoMagTM. These three systems work separately or in conjunction with one another and they are what makes Fulcrum the advanced company that it is today.
Another concept in the design of Fulcrum Wheels are the aluminum hammer head spokes which have a unique aerodynamic profile comprised of a variable truncated-cone cross-section. The rims on the Fulcrum Wheels are CNC machined which help to relieve the rim area of pointless load points. CNC machining allows the wheels to have no spoke holes on the inner groove which eliminates the need for rim tape and provides maximum torsional stiffness. Yeah, these are some serious wheels.
Fulcrum Wheels come in several models. Numbered relatively consecutively, for continuity we suppose. Although you will notice they left out the even numbers. The Racing Zeros are excellent for racing. They provide superior acceleration, are very light, have rockin' aerodynamics and roll like you're riding on air. Plus, they are super sharp looking. The Racing 1's are great for racing as well as daily rides. They are fast, stiff, smooth as well as very compliant and comfortable. They are sure to dramatically improve the handling and look of your bike. As was mentioned earlier, Fulcrum skipped over all the even numbers and went right to the Racing 3's. Racing 3 wheels are intermediate hoops. They are very durable, quiet riding and longer lasting than most wheels on the market. They are also notably faster. You will notice that you will gain speed quicker and will be able to hold it easily. They are also quite high on the bling scale. For the real heavy duty rides, or for consistent training, go for the Racing 5 model. They are durable, quiet and very long lasting. The Racing 5 Evolution wheels boast the Dynamic Balance system with two, oversized (silver) spokes to offset the rim joint for a perfectly balanced wheel. They are said to be stiff, smooth, true, and durable. They aren't the lightest wheel in the Fulcrum line, but they aren't THAT heavy either. The Racing 7's are more of a beginner's wheel. They are strong, stiff, a decent weight and come in racing red. At the very top of the line are Fulcrum's Racing Light Wheels. These wheels are Fulcrum's version of Campy's Hyperon but without the carbon bodied hugs. The Racing Light's are on a entirely different level and have earned the status as well as the price. They are one of the best all round wheels you will ever ride on. Very fast, very strong and yes, you can climb in a cog or two lower than normal. Phenomenal for climbing but also great on the flats.
