Lightweight Obermayer EVO Disc Schwartz Rear Wheel

Lightweight Obermayer EVO Disc Schwartz Rear Wheel Info

At $4,775 for a single rear wheel, the Lightweight Obermayer EVO Disc Schwartz demands to be taken seriously. This is not a wheel you buy because it looks good in photos — though it does — it's a wheel you buy because you've decided that weight, aerodynamics, and rolling efficiency matter enough to invest in the finest carbon wheel engineering Germany produces. The Obermayer EVO Disc Schwartz is Lightweight's benchmark all-road performer: 48mm deep, 662 grams, full-carbon R2R spokes, CeramicSpeed bearings, and a tubeless-ready rim that works with any modern disc brake setup. If you're running a high-end race or endurance rig and you want wheels that justify every gram of carbon in the frame, this is the rear wheel.

The Schwartz designation sets this wheel apart from the standard Obermayer EVO Disc. Where the base model uses steel bearings, the Schwartz (also known as the Schwarz ED) upgrades to CeramicSpeed ceramic bearings throughout — delivering measurably lower rolling resistance, longer service life, and a smoother, more refined feel underfoot that you'll notice on every long ride and every sprint.

Lightweight Custom Composite: Carbon Precision at Every Layer

Lightweight's in-house material technology — Lightweight Custom Composite — is the foundation of everything the brand builds. It's a proprietary carbon layup process developed specifically to minimize weight while maximizing stiffness and fatigue resistance. This isn't a wheel built around commodity carbon fiber; it's engineered at the material level for the demands of serious road riding and racing. The result is a rim that weighs as little as a carbon rim can while still meeting a 100kg maximum system weight rating and carrying a full five-year warranty.

The Obermayer EVO Disc rim is 700C hooked with a closed rim bed — a construction that improves tubeless air retention, contributes to overall rim stiffness, and creates a cleaner interface between tire bead and rim wall. At 48mm deep, it sits in a sweet spot for all-conditions riding: deep enough to benefit meaningfully from aerodynamic gain on flat and rolling terrain, shallow enough to handle crosswinds without becoming a liability. It's a depth choice that works on race day, on long training rides, and everywhere in between.

R2R Carbon Spokes: Rim-to-Rim Engineering

Conventional wheels use metal spokes — either bladed or round — tensioned between the hub flanges and the rim. Lightweight takes a fundamentally different approach with their R2R (Rim-to-Rim) spoke system. On the Obermayer EVO, 20 full-carbon spokes run directly from rim to rim across the hub, forming a single unified structural element rather than a collection of tensioned components. The carbon spokes are lighter than any metal equivalent at comparable stiffness, they don't require traditional nipples or tension adjustment over time, and they contribute to the wheel's exceptionally clean aerodynamic profile.

The spoke count — 20 front and rear — is deliberate. Fewer spokes means less aerodynamic drag and less weight, but only if each spoke is stiff and strong enough to distribute load effectively. Lightweight's carbon R2R spokes are engineered to meet that requirement. The rear wheel's 662g weight is a direct result of this spoke architecture combined with the proprietary carbon rim — a figure that puts it among the lightest disc-compatible rear wheels available at any price.

Pentagon SL Hub, DT Swiss EXP 180, and CeramicSpeed Bearings

The hub at the center of the Obermayer EVO Disc Schwartz is a Pentagon SL laced to a DT Swiss EXP 180 internals — one of the most respected freehub mechanisms in high-end wheel building. The EXP 180 uses a 3-pawl ratchet system with 36 points of engagement, offering fast pickup and a clean, quiet freewheeling sound. It's a hub mechanism used across the elite wheel segment for its combination of reliability, light weight, and serviceability.

In the Schwartz configuration, the bearings are sourced from CeramicSpeed — the Danish bearing specialist whose products are standard equipment across the professional peloton. CeramicSpeed ceramic balls offer lower friction than steel in dry and wet conditions, they resist corrosion, and they maintain their low rolling resistance over far more kilometers than a conventional bearing. For a wheel at this price point, CeramicSpeed bearings aren't a luxury — they're the appropriate specification.

The rear axle runs 12x142mm thru-axle, compatible with all modern disc brake road frames. Freehub options at RA Cycles cover Shimano/SRAM 11-speed (HG11) and Campagnolo — confirm your drivetrain before ordering. Internal rim width is 18.2mm with a 24mm external measurement, optimized for 25–32mm tires and tubeless-ready straight out of the box. Pair it with a quality tubeless tire and sealant and you have a rolling package that's aerodynamic, lightweight, and puncture-resistant in a single setup.

Five-Year Warranty and German Craftsmanship

Lightweight backs the Obermayer EVO Disc Schwartz with a five-year warranty — an unusually long coverage period for a carbon wheel, and a signal of how confident the brand is in its manufacturing quality. Every Lightweight wheel is built by hand at their facility in Germany, where production volume is intentionally limited to maintain the level of quality control that justifies the price. These are not mass-market wheels built to a cost target; they're built to a performance standard.

The Obermayer EVO Disc Schwartz rear wheel is in stock at RA Cycles in both Campagnolo and Shimano/SRAM 11s configurations. If you're building a set, the matching front wheel is available separately. Questions about fit, tire compatibility, or build options — reach out to our team.
