Retro Corner: Spinergy Rev X

Starting the first retro corner of the Human Engine, it's the Spinergy Rev-X Wheelset. The 90's was the era where designers were pushing the boundaries of cycling tech and design. The Spinergy Rev X comprised of 8 bladed carbon spokes, carbon fairing and aluminium rim. The wheels were said to be very aerodynamic for that time, however, came with two very big drawbacks.

Firstly they were heavy and lacking lateral stiffness not ideal when accelerating from the peloton or taking on a sprint finish. However, they were still widely used in the pro peloton for a good number of races.

But the real big drawback was they were a safety risk. The carbon spokes were liable to cracking and or breaking in the event of a crash essentially turning the blades into knives capable of cutting flesh. Paulo Bettini is noted to have cut his hand during a crash due to these wheels. 

As such the Spinergy Rex X wheels were banned by the UCI in mass participation races and the wheels slowly died out over time. Funnily you can still find these wheels on eBay and the observant eye may catch a view of a front wheel on a fixie whilst on the road.
