Lightweight Meilenstein EVO Disc Black Tubeless Wheelset

The Lightweight Meilenstein EVO Disc Black Tubeless Wheelset — known as the Schwarz edition — is the disc-compatible expression of Lightweight's carbon wheel engineering at its most refined. Built on 48mm-deep carbon rims with a 24mm internal width, the Meilenstein EVO Disc weighs 650g front and 730g rear, totaling approximately 1,380 grams. Handmade in Germany, these wheels are positioned as the lightest high-profile disc wheelset built for road racing — a claim that carries weight when you look at what the competition offers in the same format.

The EVO generation represents a meaningful departure from the previous Meilenstein Disc. Lightweight redesigned the wheelset for improved aerodynamics and lateral stiffness while reducing overall weight and increasing ride comfort — a combination that's genuinely difficult to execute in carbon wheel design, where gains in one area typically come at a cost in another. The 48mm rim profile delivers measurable aero returns at race speeds without becoming a liability in crosswind conditions. The 24mm internal width accommodates tires from 23mm to 32mm, giving the Meilenstein EVO Disc enough range to run it on both road race days and rougher terrain where tire volume starts to matter.

What distinguishes the Schwarz edition is the inclusion of CeramicSpeed bearings in the DT Swiss hubs. Ceramic bearings reduce rolling friction under sustained power output, and the difference is perceptible to riders who push extended efforts at race pace. The DT Swiss hubs also feature a quick-change axle system that allows the axle standard to be swapped in seconds — useful for riders running multiple bike builds or managing logistics at events.

Full Carbon Spoke Construction

All 20 spokes front and rear are full carbon fiber — not carbon-wrapped alloy or hybrid construction. Lightweight uses carbon spokes to reduce the elastic flex that conventional metallic spokes introduce under hard acceleration. The result is a more direct connection between pedal input and forward momentum, with less energy absorbed by spoke deflection. A 20/20 spoke count keeps the overall wheel weight in check while maintaining the lateral stiffness that disc brake systems demand — disc setups place higher lateral loads on hub flanges and spoke heads than rim brake configurations, which makes spoke-to-hub geometry a more critical design consideration.

Pentagon Hub System and Braking Safety

The DT Swiss hubs on the Meilenstein EVO Disc use what Lightweight calls a pentagon hub system — a spoke attachment geometry engineered to manage the concentrated stress that disc braking places on hub flanges during sustained hard braking. On long descents, lateral forces through the hub increase significantly compared to rim brake setups. The pentagon geometry distributes those loads more evenly across the flange, reducing the stress concentration at individual spoke eyelets. For a carbon wheelset at 1,380 grams total, maintaining structural integrity under repeated high braking loads without adding material is one of the central engineering challenges — the hub geometry is part of how Lightweight addresses it.

Tubeless Ready, Disc Brake Compatible

The Meilenstein EVO Disc runs tubeless or clincher with tire widths from 23mm to 32mm. The tubeless setup is the natural configuration: it allows lower tire pressures, which improves road vibration absorption and traction — particularly relevant on a stiff wheelset where ride quality is otherwise determined almost entirely by tire choice. Disc brake compatibility is through CenterLock, covering the standard hub interface for modern road and gravel disc platforms. The axle standard is 12x100mm front and 12x142mm rear, with a maximum recommended rider weight of 265 lbs.

Drivetrain Compatibility

RA Cycles carries the Meilenstein EVO Disc Black in three configurations: Campagnolo, Shimano/SRAM, and XDR Driver for SRAM's 12-speed XD freehub standard. All three variants share identical rim, spoke, and bearing specifications — only the rear freehub body differs between options.

At approximately 1,380 grams with CeramicSpeed bearings, carbon spokes, and DT Swiss hubs with the pentagon braking system, the Meilenstein EVO Disc Black sits at the top of the disc road wheel market on the metrics that matter most to performance-focused riders. For those building a dedicated race day setup around a disc brake frame, it is a difficult wheelset to argue with.
