Aerolite Pedals were created in 1979 by Roger Sanders, a physician's assistant. In his work, Sanders had witnessed injuries resulting from popular toe clip and strap pedal connections, and desired a safer alternative.
The most recent edition to Aerolite's line of ultra light pedals is a variation on the same theme. Weighing in at a mere 99 grams including both pedals and cleats, the carbon matrix aluminum spindle proves to be even lighter and up to 2x as stiff as the the earlier titanium versions. With such a rigid platform, its almost a guarantee that you'll have a significant increase in power transfer to the cranks.
Continuing their reputaion for a considerably light and extremely safe pedal, Aerolite has tested their CLA lite pedals to shear crack tests of more than 6,000 foot pounds of torque.
Design and Operation
The Aerolite's design is simple - a cylindrical pedal paired with a plastic cleat that wraps 304 degrees around the pedal when engaged. An upward force of over 1300 pounds would be required for the cleat to release with normal pedaling efforts. However, proper release of the clip is relatively easy, requiring a natural supination of the ankle. With this outward rotation, the cleat is released slowly and the foot rolls easily off the pedal.
Design changes for 2015
For 2015, the Aerolite CLA pedal has been slightly redesigned to improve overall stiffness and longevity of the pedal spindle. By increasing the diameter of the CLA spindle significantly, Aerolite is able to ensure a quality product with remarkably low weight and noticeable rigidity.
Aerolite pedals are proudly and entirely manufactured in the USA; even the materials and packaging are sourced in America.
Aerolite's time trial specific pedals come equipped with shorter spindles for a narrower overall Q factor. This version also features a drilled out Turcite sleeve. Initial tests performed at MIT have shown that these changes over the standard Aerolite design slightly increase an already impressive bearing efficiency. It should also be noted that the Aerolite cleat-pedal-shoe interface has performed well in static aerodynamic tests, making it an excellent choice for the discerning time trial racer.
