When we set out to create the CLX 50, we had clear goals in mind—create wheels that are 48 to 54mm deep, aerodynamically optimized, ultra-wide, and under 1400 grams. This meant that they'd have to borrow some weight savings techniques that we developed for the CLX 32, while taking some aero guidance from the CLX 64, if we were going to create what we like to call “the unicorn wheel."
Even though the CLX 50 is similar in weight to many wheels in the “lightweight” category, aerodynamics came at the forefront of the development. With this, we jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CLX 50 as fast and light as possible. It took a while, but we narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel.
In the tunnel, we tested every wheel, ours and the competition's, with a 24C tire (measuring 26C), as tires can drastically affect testing. We chose a modern-width tire to design our rims around, because they not only allow for less tire pressure (which results in more comfort and less rolling resistance) but are also just as aerodynamically efficient when paired with the correct rim width.
After finding the optimized rim shape that supported our svelte weight requirements, we opted to lace the rims, via 16 DT Swiss Aerolite spokes, to our Aero Flange (AF) hub with the legendary CeramicSpeed bearings. And when it was time for final testing validation, we were left with a 50mm-deep, 1375-gram clincher wheelset that's not only ~200 grams lighter than the competition’s similar depth wheel, but is also measurably faster in every conceivable test than each wheel in its category.
