Lightweight Obermayer EVO Disc Tubeless Wheelset

There are carbon wheelsets, and then there are Lightweight Obermayer EVO Disc Tubeless wheels. The German manufacturer has been setting the standard for ultra-light carbon wheel construction for decades, and the Obermayer EVO represents the current state of that pursuit: a disc-specific, tubeless-ready wheelset built around a true monocoque carbon structure — rim, spokes, and hub shell engineered as a single continuous unit rather than assembled from separate components. At $8,095 and approximately 1,230 grams for the complete set, it occupies a category that very few wheelsets can credibly claim to share.

What separates Lightweight from the carbon wheel market at large is not rim depth or aerodynamic profile — it’s manufacturing philosophy. Most carbon wheels use carbon rims with separate aluminum or carbon spoke nipples, traditional metal hubs, and mechanical connections between structural elements. Lightweight rejects that approach entirely. The Obermayer EVO is built using LCC (Lightweight Custom Composite) Carbon, a proprietary material combining ultra-thin prepregs with advanced fiber types that enables thinner walls, greater stiffness, and lower weight than conventional carbon layup. The entire wheel is formed in a single mold — a genuinely monocoque structure — where no mechanical fasteners connect the load-bearing elements. The result resists torsional deformation in a way that assembled wheels cannot replicate.

The 48mm rim depth places the Obermayer EVO in a versatile all-road range — deep enough to contribute meaningfully to aerodynamic efficiency at race speeds, shallow enough to remain manageable in crosswinds and practical for climbing where rotational weight matters. At 568 grams front and 662 grams rear, the per-wheel figures are what truly distinguish this wheelset. These are numbers that climbing stages and hilly one-day races are decided on, and Lightweight has engineered the Obermayer EVO explicitly for exactly those conditions.

Design Benefits

1. R2R (Rim-to-Rim) Carbon Spoke Design: The Obermayer EVO’s 20 full-carbon spokes run in continuous uninterrupted lines from rim to rim, passing through the Pentagon SL hub without bends, breaks, or mechanical connectors. The spokes are permanently bonded to the hub using high-performance adhesive rather than threaded nipples. This construction eliminates every mechanical interface that traditional wheelsets use as connection points — and every one of those interfaces is a potential flex point, a source of fatigue, or a maintenance variable. Lightweight’s R2R design handles up to 1,800kg of tension per spoke and delivers triple the stiffness of an equivalent steel spoke at a fraction of the weight.
2. LCC Carbon Monocoque Construction: Lightweight Custom Composite carbon uses ultra-thin prepreg layers combined with advanced fiber types to produce a material that enables thinner structural walls without sacrificing strength. Formed in a single mold, the Obermayer EVO is a true monocoque structure — not a rim bonded to separate spokes, but a unified carbon unit where the load path runs continuously through the material. The resistance to torsional deformation this construction provides is one of the primary reasons Lightweight wheels have a reputation for translating pedaling effort into forward motion with minimal energy loss.
3. ART (Alpha Rib Technology): Hidden internal rib structures reinforce the hollow rim cavity, distributing lateral forces across the rim’s cross-section rather than concentrating them at stress points. ART allows Lightweight to maintain the structural integrity the rim needs under hard cornering and sprint loads while keeping the walls as thin and light as possible. This is not a feature visible from the outside — it’s internal engineering that makes the weight figures achievable without making the rim fragile.
4. Pentagon SL Hub: The hub shell’s polygonal shape creates a mechanical geometry that Lightweight describes as optimizing the flow of power from the tire contact patch through to the drivetrain. Beyond the structural design, the Pentagon SL hub saves 70 grams over the previous hub generation — a meaningful reduction in unsprung rotational mass that contributes directly to the wheelset’s acceleration feel. At this price point, the hub is not a cost-reduced component carrying an expensive rim; it is an engineered element designed as part of the complete structural system.
5. Aerodynamics Developed Through CFD and Wind Tunnel Testing: The 48mm rim profile was shaped using computational fluid dynamics modeling and wind tunnel validation, balancing aerodynamic drag reduction against crosswind stability. For a wheel positioned primarily as a climbing and all-road performance tool, the aero development matters: at race speeds on flat or rolling terrain, drag reduction from rim profile contributes to sustained speed, and the 48mm depth is shallow enough that it doesn’t become a liability in the conditions where these wheels are most likely to be ridden hard.

Final Take

The Lightweight Obermayer EVO Disc is for riders who have reached the point in their equipment thinking where the question isn’t which carbon wheelset to buy, but which carbon wheelset is genuinely worth the investment at the top of the market. Lightweight’s answer — monocoque construction, rim-to-rim carbon spokes, handcrafted German manufacturing, and a complete weight of 1,230 grams in a disc-specific tubeless-ready package — is a compelling one. These wheels are not for everyone, and they are not priced like they are. They are for riders who understand what they are buying and why it matters at the level they ride.
