Juego de ruedas ligeras Fernweg 85 EVO Pro Disc

The Lightweight Fernweg 85 EVO Pro Disc starts with a premise most wheelmakers won't touch: build a set of 85mm carbon clinchers that weighs 1,665g — and then make everything that achieves that number structurally irreplaceable. No nipples. No threads. No tension to manage. The spoke is carbon, the rim is carbon, and the connection between them is permanent.

That connection is R2R — Rim-to-Rim — Lightweight's most significant structural innovation. Each of the 20 full-carbon spokes runs continuously from one rim flange to the other, bonded in place with aerospace-grade adhesive rather than threaded through a nipple. The result is a spoke that can't loosen, can't corrode, and transmits load without the mechanical energy loss that threaded connections introduce. At 85mm deep, the Fernweg already generates real aerodynamic return on flat roads and in crosswinds. R2R makes sure nothing in the wheel's construction is working against that.

The rim itself is built with LCC — Lightweight Custom Composite — Lightweight's proprietary carbon layup developed over nearly four decades in Friedrichshafen, Germany. The 24mm external profile and 18.2mm internal width are sized for modern tubeless tires in the 25–32mm range, and the closed rim bed and hooked bead design give you a stable tubeless setup that seats predictably. 700C, 12×100mm front, 12×142mm rear — standard fitment for modern disc road builds.

Design Benefits

1. R2R spoke technology: Rim-to-Rim carbon spokes are adhesive-bonded — no nipples, no threads, no tension degradation over time. The spoke becomes a structural part of the wheel rather than a component that can work loose.
2. Pentagon SL Hub: The hub's polygonal shape distributes load more evenly across the shell, saving 70g per set compared to a conventional hub profile. CeramicSpeed bearings reduce friction and handle heat more effectively — relevant when you're descending with disc brakes generating sustained thermal load.
3. LCC carbon construction: Lightweight's proprietary layup uses carbon fiber selected and oriented for the Fernweg's specific load cases — not a generic carbon spec applied across a product range. Nearly four decades of refining this process in Friedrichshafen is embedded in the rim.
4. 85mm depth at 1,665g: The combination matters. Deep section wheels are common. 85mm wheels at this weight are not. The Fernweg EVO Pro Disc gives you a genuinely aero wheelset without the weight penalty that makes deep section rims a liability on climbs.
5. Tubeless-ready hooked rim: The closed rim bed and hooked bead allow tubeless setup without inserts or workarounds. The 18.2mm internal width is optimized for 25–30mm tire widths — the current standard for aero road and triathlon builds.

Final Take

The Fernweg 85 EVO Pro Disc is built for riders who want a deep section wheelset that doesn't make compromises. The 1,665g claimed weight at 85mm depth is the headline, but the engineering underneath — R2R spokes, Pentagon SL hubs, LCC carbon — represents a coherent approach to removing every gram that doesn't need to be there. Five-year warranty, multi-driver compatibility (Shimano, SRAM XDR, Campagnolo, N3W), and nearly four decades of manufacturing experience behind every pair. If you're building a fast disc road bike and want wheels that perform at the top of the aero category without giving anything back on climbs, this is where the search ends.
