Lighweight Autobahn Tubular Disc Wheel

The Lightweight Autobahn Tubular Disc Wheel is not a product you stumble into. It's a deliberate choice — made by riders who have stripped away every variable they can control and arrived, finally, at the wheel. Lightweight has been building full-carbon wheels in Germany for decades, and their reputation in time trial and triathlon circles is built on something more durable than marketing: consistent, obsessive execution at the highest level of the sport.

A disc wheel's aerodynamic argument is well understood. No spokes means no turbulence, no flex points, no air disturbance on the trailing side of the wheel. What separates a Lightweight disc from a commodity alternative is what happens once you're on the road — the quality of stiffness, the way power transfers without conversation, the particular silence that comes from a wheel that isn't working against you. The Autobahn Disc is built on full-carbon construction, designed to deliver the kind of lateral rigidity that makes a rear end feel planted rather than compliant. In a time trial, that matters more than most riders expect until they've experienced the difference firsthand.

This is a wheel for a specific kind of effort — the kind where position is dialed, pacing is calculated, and every system on the bike has been optimised for a single measured output. The Autobahn Disc doesn't have a road application. It doesn't need one. Available in both Shimano/SRAM and Campagnolo freehub configurations, it integrates cleanly into a purpose-built race setup without asking you to compromise anywhere in the drivetrain.

Design Benefits

1. Full-Carbon Disc Construction: The solid carbon disc profile eliminates the aerodynamic disruption created by spoked wheels entirely, allowing air to pass cleanly around the rear of the bike. Lightweight's carbon layup process — refined over decades of high-level racing — is designed to produce a disc that is both exceptionally light and structurally rigid, without trading one quality for the other.
2. Lateral Stiffness for Direct Power Transfer: In a time trial, the rear wheel is a direct conduit between your effort and your speed. The Autobahn Disc's stiff carbon structure is engineered to minimise lateral flex, meaning the power you generate reaches the road without being absorbed by the wheel itself. Riders who have trained for months to produce a specific watts-per-kilogram figure deserve a drivetrain that honours that work.
3. Tubular Tyre Interface: Tubular construction remains the preferred choice at the elite level of time trialling for good reason — lower rolling resistance, higher inflation pressures, and the ability to continue riding on a flat rather than a sudden catastrophic failure. Paired with a high-quality tubular tyre, the Autobahn Disc gives you a rear contact patch optimised for speed on smooth race-day roads.
4. Disc Brake Compatibility: Unlike older disc wheel designs built around rim brake tracks, the Autobahn Disc is designed for disc brake systems — removing heat build-up from the carbon rim structure entirely and bringing braking performance in line with modern thru-axle race bikes. The transition to disc-brake time trial frames has been gradual but is now firmly established at the professional level, and this wheel is built for that architecture.
5. Drivetrain Flexibility: Offering separate variants for Shimano/SRAM and Campagnolo freehub standards means the Autobahn Disc slots into the drivetrain you already run, without adapters or workarounds. For athletes who have invested in a specific groupset ecosystem, that compatibility removes one more variable from race-day preparation.

Final Take

The Lightweight Autobahn Tubular Disc Wheel is built for athletes who race against the clock — triathletes and time triallists who treat equipment selection as part of the discipline itself. If you are running a disc-brake time trial or triathlon bike and you want a rear wheel that reflects the same level of commitment you bring to training, the Autobahn Disc delivers exactly what Lightweight has always delivered: German-built carbon work, executed without shortcuts.
