Lightweight Fernweg EVO 63 Disc Rear Wheel Black Edition

Lightweight Fernweg EVO 63 Disc Rear Wheel Black Edition Info

Lightweight didn't just make a good carbon wheel. They made the carbon wheel — one of the first full monocoque carbon road wheels ever produced, hand-built in Germany since the 1990s, long before carbon rims became an industry standard. The Fernweg EVO 63 Disc is the current expression of three decades of refinement: a 63mm full-carbon rear wheel with carbon spokes, a proprietary pentagon hub, CeramicSpeed bearings, and a Black Edition finish that keeps every surface — rim, spokes, decals — entirely matte black. At 885 grams for the rear wheel alone, it represents what happens when the pioneers of a category keep pushing after everyone else catches up.

This is not a wheel for riders deciding whether to go carbon. It's for riders who have already decided, and want the best one built.

Full Carbon Construction — Rim, Spokes, and Everything Between

Most carbon wheels use carbon rims with metal spokes. The Lightweight Fernweg EVO 63 is not most carbon wheels. The spokes are full carbon — 20 of them front and rear — integrated into the construction in a way that eliminates the energy dissipation that occurs at metal spoke nipples and the weight penalty of steel or aluminum tensioning hardware. Carbon-to-carbon spoke-to-rim interface means direct, uninterrupted power transfer from hub to road: every watt you put into the pedals arrives at the tire contact patch without rounding off through a metal mechanical joint.

The rim itself is 63mm deep with a 25mm external width and 18.2mm internal width — an aerodynamically optimized profile developed for modern tire widths in the 25-32mm range. The monocoque construction process, in which the rim is formed as a single continuous carbon structure rather than assembled from separate pieces, produces a wheel that is stiffer, lighter, and more consistent unit-to-unit than any bonded construction approach. Lightweight draws on engineering principles from aerospace, industrial, and medical manufacturing — industries where structural precision is non-negotiable — and applies them to a rim that has to survive the lateral forces of a sprint, the thermal stress of a long mountain descent, and the repeated impacts of real road surfaces.

The rear wheel weighs 885 grams. For a 63mm disc-compatible carbon wheel with full carbon spokes and premium bearings, that number is genuinely exceptional. It's the product of three decades of refinement by a brand that has been building nothing but carbon wheels since before most of their competitors existed.

Pentagon SL Hub and CeramicSpeed Bearings

The hub is Lightweight's proprietary Pentagon SL design — not an adapted DT Swiss or Chris King unit, but a hub developed in-house specifically for the Fernweg EVO's disc brake loads and carbon spoke interface. The pentagon geometry at the rotor mounting interface distributes braking forces more evenly across the hub shell than a conventional circular interface, which becomes meaningful on long descents where sustained high braking loads are applied through a 12mm thru-axle to a carbon structure. The result is improved safety and feel under hard braking, particularly on extended downhill sections where conventional hub designs can generate perceptible heat and flex.

CeramicSpeed bearings run throughout. This is not an aftermarket upgrade or a marketing addition — the Fernweg EVO is built with CeramicSpeed from the factory because it's the correct bearing for a wheel at this level. Ceramic bearing balls run with lower friction than steel, don't corrode, and maintain consistent performance across a wider temperature range. The rotational efficiency difference is measurable, and over the course of a long race or training ride, the cumulative effect on power required to maintain speed is real. CeramicSpeed bearings also last significantly longer than steel equivalents under road conditions, which matters when the hub they're fitted into costs what a complete wheelset does from most brands.

63mm — The Aerodynamic Case for This Depth

A 63mm rim depth is a meaningful choice, not an arbitrary number. Below 50mm, aerodynamic benefit diminishes relative to the weight penalty of a deeper rim. Above 70mm, crosswind handling begins to compromise the wheel's usability in the variable conditions that characterize real road racing. At 63mm, the Fernweg EVO sits in the performance window where aerodynamic drag reduction is maximized without the handling liability that comes with a full-depth wheel.

The rim profile is optimized for modern tire widths — the 25mm external width creates a smooth transition from tire sidewall to rim that reduces turbulence at the leading edge. Lightweight developed the shape for tubeless use primarily, and the construction reflects that: the rim bed is optimized for tubeless seating and the internal width accommodates 25-32mm tires at their intended profile. The aerodynamic development is built around tires mounted at real-world widths, not the narrowest tire that technically fits.

The Black Edition

The standard Fernweg EVO has Lightweight's characteristic grey and silver graphics. The Black Edition — Schwarz Edition in the original German — replaces every surface with black: matte black rim, black carbon spokes, black decals. The result is a wheel that disappears visually into dark frames and makes a strong case on lighter ones. It's the version for riders who want the performance without the branding.

Beyond the aesthetic, the Black Edition specification is identical to the standard Fernweg EVO 63 Disc: same carbon construction, same Pentagon SL hub, same CeramicSpeed bearings, same 885g rear wheel weight. This is the wheel for the rider who has done the research, understands what they're buying, and has decided that nothing else will do. Compatible with Shimano and SRAM 11-speed cassettes via the HG11 freehub body; 12x142mm thru-axle standard.
