Kolesá Specialized Roval CLX 64 Disc 28" karbónové - kotúčové, galuskové

When Specialized set out to create a wheelset built purely for speed, they wanted to make it more than just fast. Not that being fast wasn’t a priority, but they were tired of wheels that only performed well in a straight line. In the end, Specialized developed the CLX 64 Disc, the fastest wheel that they've ever tested with all of the performance benefits of disc brakes Specialized have come to love. This iteration has a more impact-resistant rim, a disc-specific carbon layup that optimizes stiffness and weight, and incredible brake modulation and power in all conditions.

One of the first questions Specialized get about the CLX 64 is, “Why 64mm instead of 65mm?” To put it simply, it's because 64mm simply tested faster than 65mm. One millimetre - that's how deep the testing goes. Having an in-house wind tunnel allows Specialized to run every possible variation, and after two years of development, 80 variations in rim design, and nearly 300 hours studying tire and frame interactions in the Wind Tunnel, they found 64mm to be the fastest iteration for normal riding conditions. In fact, it's even faster than the 80-plus-millimeter-deep wheels they were tested against. Being able to use a shape that’s nearly 20mm shallower than the competition, yet just as low in drag, makes for a wheel that has drastically less side force and steering torque. This translates to less buffeting and more confidence in even the gustiest winds.

Another positive of a shallower rim depth is the reduction in weight that follows using less material. Many deep carbon wheels feel “slow” due to their high inertia value. What's that? Inertia is the amount of force it takes to accelerate or decelerate, and wheels that are built around heavier rims lack the liveliness that many riders crave. Being over a half-a-pound lighter than the other wheels in its aero category, the CLX 64 accelerates, decelerates, and changes direction with less effort.

The rim is not the only component of the CLX 64 that contributes to its aero prowess though - in order to create the fastest wheels, Specialized focused on the wheels as a system, not just a rim with “other parts,” and the Aero Flange (AF) hubs play a significant role. Designed completely in the Win Tunnel, the AF hubs feature an incredibly small frontal aero, without sacrificing stiffness, making them aerodynamically efficient.

To top off the multitude of performance features of the rim, Specialized chose the highest quality build components to pair the CLX 64 with. Starting with DT Swiss Aerolite bladed spokes, which test faster than their round counterparts in the Win Tunnel, Specialized hand-laced the 64 rim to the AFD hubs that house CeramicSpeed’s legendary bearings and DT 240 hub internals. Why hand-built? Machines make mistakes and mistakes aren't something they're ok with, so Specialized has real people lace each wheel by hand.
