DT SWISS is a Swiss manufacturer of bicycle components best known for its high-performance wheels, hubs, rims, spokes, and nipples, as well as mountain-bike suspension products. Headquartered in Biel/Bienne, Switzerland, the company operates under the philosophy of “Engineering Performance.”[1]

The company’s official address is Längfeldweg 101, CH-2504 Biel/Bienne, Switzerland.

Origins before DT SWISS

The history of DT SWISS predates the company’s formal establishment in 1994. The designation “DT” is derived from the German Drahtwerke and French Tréfileries, both translating to “wire works.” This nomenclature reflects the brand’s origins in the multilingual city of Biel/Bienne and its historical wire-production industry.[2]

The company traces its roots to Vereinigte Drahtwerke, a wire manufacturer based in Biel. Its expertise in precision wire production eventually became critical for manufacturing bicycle spokes. By 1994, the entity had established a significant reputation for high-quality bicycle spokes.

1994: Founding of DT SWISS

In 1994, Frank Böckmann, Maurizio D’Alberto, and Marco Zingg founded DT Swiss AG following a management buyout from Vereinigte Drahtwerke in Biel.[1] This event marked the beginning of DT SWISS in its modern corporate form. While the initial focus remained on spokes and wire technology, the company subsequently expanded vertically into other wheel components.

1995: Hub technology

A pivotal development occurred in 1995 when DT SWISS acquired the exclusive license for the Hügi Ratchet System technology. The company began manufacturing and distributing its own hubs, introducing ranges for both road and mountain bikes.[1] This acquisition allowed DT SWISS to transition from being primarily a spoke manufacturer to becoming a complete wheel-system company.

1996: North American expansion

In 1996, DT SWISS established DT Swiss Inc. in Grand Junction, Colorado. This facility included dedicated spoke production alongside sales and marketing operations, securing a presence in the North American cycling market.[1]

1999: Spoke nipples

DT SWISS expanded its component range in 1999 by introducing a broader selection of brass and aluminum spoke nipples in various sizes and colours. This move highlighted the company’s approach of developing individual components that determine overall wheel performance rather than treating wheels as simple assemblies of rims and hubs.

Over subsequent decades, DT SWISS evolved from a specialist spoke manufacturer into a globally recognised wheel-system manufacturer. Its product portfolio grew to encompass hubs, rims, spokes, nipples, complete wheelsets, wheel-building systems, axle and wheel-retention systems, and suspension components.

Today, the components business focuses on rims, hubs, RWS, spokes, and nipples, while the wheel technology portfolio includes hub, rim, spoke, hand-building, and suspension technologies.[1]

Bicycle wheels

Wheels are the most recognisable product category of DT SWISS. The company produces wheels for multiple disciplines, including road, gravel, mountain biking, cross-country, trail, enduro, downhill, cyclocross, e-bike, and hybrid commuting applications. Wheel ranges utilise specific combinations of carbon or aluminium rims, hub platforms, and spoke technologies tailored to each discipline. All wheelsets are tubeless compatible and supplied tubeless ready with tape and valves.[1]

Major wheel families

Key DT SWISS wheel families include:

• ARC: Aerodynamic road-oriented wheels
• ERC: Endurance and gravel-oriented wheels
• PRC: Performance road carbon wheels
• XRC: Cross-country MTB
• XMC: Trail and all-mountain MTB
• EXC: Enduro MTB
• HXC: E-MTB
• GRC: Gravel

The specific lineup is updated periodically as new product generations are released.

Hubs

Hubs represent a signature technology for DT SWISS. Current hub families include the 180, 240, 350, and 370 series, which occupy different tiers within the product hierarchy:[1]

• 180: Premium and highest-end
• 240: High-performance
• 350: Performance and durability
• 370: Accessible and entry-level

The DT Swiss 180 serves as the premium hub, combining the Ratchet EXP freehub system with SINC ceramic bearings.[1]

Ratchet System

The Ratchet System is one of the technologies most strongly associated with DT SWISS. Unlike conventional pawl-based freehubs, the original system uses two precision-machined toothed rings that engage simultaneously. The load path transfers from pedalling to the freehub body, then through the ratchet rings to the hub shell and wheel.

The system is noted for high load capacity, fast engagement, durability, simple mechanical construction, and ease of servicing. DT SWISS describes it as a patented freewheel system using high-precision star ratchets.[1] The later Ratchet EXP system further refined this concept to reduce weight while improving integration and durability.[1]

Spokes

Spokes remain fundamental to the identity of DT SWISS, reflecting the company’s origins in wire production. The current spoke range includes:[1]

• DT Aerolite
• DT Aerocomp
• DT Revolite
• DT Revolution
• DT Competition
• DT Competition Race
• DT Alpine III
• DT Champion

Rims

DT SWISS manufactures both aluminium and carbon rims designed around priorities such as low weight, aerodynamics, impact resistance, tire support, tubeless compatibility, stiffness, and durability. The company employs proprietary manufacturing techniques for carbon rims, including processes that emphasise layer compression and nondestructive inspection.[1]

Suspension

DT SWISS has expanded beyond wheels into mountain-bike suspension. The portfolio includes forks, rear shocks, and dropper posts. The naming convention uses prefixes such as F (fork), R (rear shock), and D (dropper post), seen in models like the F 232, R 535, and D 232.[1]

In 2023, DT SWISS transferred suspension production from Asia to Poland, where assembly now takes place.[1]

RWS

RWS (Ratchet Wheelmounting System) is a wheel retention technology that uses a threaded mechanism to generate high clamping force rather than relying on a traditional quick-release lever. It is designed to secure wheels safely and quickly and has been offered in 5, 9, 10, 12, and 15 mm axle configurations.[1]

DT SWISS employs a systematic nomenclature for its products. For example, the name ERC 1100 DICUT decodes as follows:

• ERC: Wheel and rim category
• 1100: Hub level
• DICUT: Wheel family and spoke construction

Letters indicate the category and rim material, numbers denote the hub level, and additional text specifies the wheel family and spoke type.[1]

Hub hierarchy

The hub numbering system indicates general positioning:

• Ratchet System: The iconic toothed-ring freehub mechanism.
• Ratchet EXP: A lighter, more integrated evolution of the Ratchet concept designed to maintain durability while reducing weight.[1]
• SINC Ceramic Bearings: Premium ceramic-bearing technology designed for low rolling resistance.[1]
• Aero+: An approach used to optimise the aerodynamic performance of wheel and tyre combinations.[1]
• OXiC: An electrochemical ceramic coating applied to certain aluminium rims to create a hard, wear-resistant surface.[1]
• PHR: Pro Head Reinforcement system that increases the load-bearing surface around the nipple area to distribute stress through the rim.[1]
• Pro Lock: A thread-locking technology for spoke nipples designed to enhance wheel build durability.[1]
• Hand-built wheels: DT SWISS emphasises experienced hand-building, noting that expertise is essential for producing high-quality wheels.[1]

The corporate structure reflects the evolution from wire manufacturing to a comprehensive component ecosystem:[1]
