How we work

We operate with precision, clarity, and consistency – as your extended engineering and sourcing team in Taiwan. By combining German structure with Taiwanese agility, we deliver technical depth with on-the-ground responsiveness. Every project is clearly defined, closely monitored, and verified directly on site – not from behind a screen. Communication is technical, direct, and efficient – not filtered through generic sales channels. Our clients work with experienced engineers and project managers who understand the full scope, from development to production.

We believe in cooperative, goal-oriented partnerships – built on mutual trust and hands-on collaboration. Together, we solve problems early and move projects forward with shared commitment.

Bilateral Engineering Dialogue
We work directly with your technical team – defining tolerances, selecting materials, and developing sampling strategies that match your specifications. Communication is technical, efficient, and focused on real-world constraints.

On-Site Presence, Not Just Messaging
With over 80% of our suppliers located within 40 minutes of our office, we visit production sites on a regular basis. Key decisions are made on-site, directly at the machine – not just through messages or calls.

Defined Process Framework
Every project follows a documented structure: quotation, DFM, sample approval, production, inspection, shipment. All steps are managed using ERP, CRM, Exchange and encrypted cloud systems. Transparent and trackable – for both sides.

Consistent Team, No Turnover
Since our founding in 2011, the core ADG team has remained unchanged. This consistency ensures long-term reliability and preserves technical know-how – a rare quality in the sourcing business.

Confidential & Discreet
ADG does not disclose client names or publish reference lists. All development projects are handled under strict confidentiality.
Non-Disclosure Agreements (NDAs) are in place with both customers and suppliers. Sensitive data, drawings, and project details are shared only on a need-to-know basis, supported by encrypted communication and controlled document access.

Quality Control from Sample to Shipment
Every shipment – from initial prototypes to full container loads – is inspected according to defined checklists. Depending on the product, this can include dimensional checks, cosmetic inspection, function testing, and assembling and packaging review.

Established Lab Partnerships
Since the beginning of ADG Technology, we’ve cooperated with Taiwan’s leading testing institutes, including SGS and CHC (TÜV Süd), giving us fast and reliable access to certified third-party testing.

Norm-Based Testing and Beyond
We conduct testing according to international standards such as ISO and MIL-STD – but our procedures often exceed standard requirements. On request, we support elevated specifications: higher forces, extended cycle counts, and special setups for extreme use cases. Where no standard exists, we develop customer-specific test protocols.

Regulatory Compliance
We support regulatory testing and documentation upon customer request. This includes conformity with environmental and safety standards such as RoHS, REACH, and California Prop 65.

Designed for Volume
Our infrastructure and workflows are built to handle production at scale – including high-volume items like rims, fasteners, or forged components. Sampling, inspection, and data tracking based on batch and serial numbers are integrated into our process.

Direct Factory Collaboration
We work directly with manufacturers – not traders. This gives us visibility into every step of the production process and eliminates extra layers and markups often found in over-trading models.

Problem Solving with a Partnership Mindset
Manufacturing challenges are part of the process. Our approach is solution-oriented and transparent – we work side by side with both customers and factories to resolve issues quickly and constructively.

In-House & On-Site Engineering
We define specifications in detail, visit factories frequently, and verify production steps personally. On-site presence allows for fast feedback loops and higher process stability.

Deep Supply Chain Control
Many of our manufacturing partners have high vertical integration – starting with raw material production. This depth enables tighter control over tolerances, performance, and consistency.

Environmental & Labor Standards
We choose partners who follow proper environmental procedures – such as certified wastewater handling in surface treatments – and who provide safe, regulated working conditions in line with Taiwanese labor law.

Proximity Enables Immediate Action
Over 80% of our manufacturing partners are located within a 40-minute radius of our facility. In many cases, we are on-site within 20 minutes. This allows us to intervene directly and immediately in case of technical issues – without international travel, long scheduling delays, or reliance on remote intermediaries.
By contrast, suppliers operating across borders – for example from Taiwan to Southeast Asia – often refrain from traveling when problems arise. As a result, issues may be downplayed, delayed, or miscommunicated. Our local presence enables transparent, accountable, and timely corrective actions. It also reduces emissions from unnecessary business travel.

On-Site Engineering Collaboration
Technical alignment occurs at the production site, not via messenger apps or delayed email threads. We work directly with process engineers and machine operators – in their language and environment – which significantly reduces misunderstandings. Complex matters are resolved more efficiently when discussed on the shop floor.

Cultural Emphasis on Accountability
Taiwanese manufacturing culture, shaped by Confucian and Japanese influences, places a high value on responsibility, continuity, and quality. Reputational concerns and professional pride play a central role in ensuring that commitments are honored. The compact industrial landscape means that suppliers know each other – and underperformance is difficult to hide.

Structured Labor Practices and Safety Standards
Taiwan maintains clear and enforceable labor and safety regulations. Most of our partner factories offer structured, well-documented processes, trained personnel, and modern workplace environments. Compared to operations in lower-cost countries, production sites in Taiwan show significantly higher levels of compliance, traceability, and worker retention.

Predictable Quality Over Cost-Cutting
While many companies shift production to regions with lower wages, we prioritize consistency, traceability, and process integrity. Taiwan may not offer the lowest price per unit – but it delivers repeatable quality, reduced rework, and fewer production incidents. This long-term reliability offsets initial cost differences.

We develop and supply a wide range of MTB, road, and gravel handlebars, stems, and seatposts – in aluminum, carbon, and titanium.

Our aluminum handlebars are not bent on traditional tube machines, but formed using precision external dies that define both geometry and surface finish in two steps. This eliminates post-processing such as manual grinding – ensuring uniform wall thickness and consistent fatigue performance.

Our carbon handlebars and seatposts are made from customized prepregs produced on-site, using fibers from leading suppliers such as Toray, Toho, Mitsubishi, and Formosa. We can integrate Dyneema® layers for enhanced impact resistance, and offer recyclable resin systems on request.

Titanium handlebars and seatposts are fabricated from in-house drawn and butted tubing, shaped and formed to customer specification.

We also produce aluminum, carbon, and titanium stems – forged or CNC-machined for aluminum, usually forged or welded for titanium, then precision-finished.

Additionally, we support the development and production of pedal components, including steel and titanium axles, pins, clipless pedal parts, seals, and bearing systems.

We develop and supply drivetrain parts such as forged aluminum or titanium crank arms, chainrings, and bottom brackets – often with specialized features like stainless-steel or ceramic bearings, customized axle lengths, or proprietary interfaces.

We also support the production of 3D hollow-forged cranksets and crank blanks for further machining – including carbon crank development on request.

A major focus lies in rim manufacturing. Our aluminum rims are welded or sleeved, made from custom alloys that are smelted in-house for full material control. Profiles can be open-mould or extruded to customer specs. Multi-angle drilling reduces spoke stress, and every rim is 100% inspected for runout and weight consistency. Multi-chamber designs are available for increased strength.

Our carbon rims are made from customized prepregs – produced directly at the manufacturing site using fibers from Toray, Toho, or other Tier-1 suppliers. Dyneema® impact layers can be integrated, and recyclable matrix systems are available upon request.

Testing is performed to ISO fatigue standards or according to elevated customer requirements.

Our suspension development experience dates back to 2006, supported by tuning know-how gained since 1996. We’ve contributed to projects involving forks, rear shocks, and dropper posts – covering everything from individual components to fully integrated systems.

We support the development and production of functional interface components such as seals, bushings, bearings, and spring elements. Our scope ranges from custom-molded elastomeric parts to fully assembled bearing units, tailored to specific loads, kinematics, and environmental conditions.

Elastomeric solutions include seals, wipers, and co-molded, steel-reinforced elements. We use materials such as NBR, FKM, HNBR, EPDM, TPE, MCU, and proprietary blends – with optional low-friction surface treatments like Teflon coatings.

In selected projects, we work in direct coordination with global specialists such as Trelleborg, Saint-Gobain, or IGUS – to align materials, geometries, and tolerances to specific use cases.

Our bearing portfolio includes standard and customized bushings and ball bearings – with options like full-complement or caged designs, stainless or ceramic balls, and custom-color housing seals.
Bushings are manufactured from low-friction polymers, optimized for load direction and wear behavior.

We also supply elastomer and steel springs in carbon steel, stainless, or titanium – including linear and progressive types for suspension and structural damping applications.

We design and produce custom packaging solutions tailored to a wide range of products – with a strong focus on minimizing pack volume and using recycled and recyclable materials wherever possible. Especially for goods shipped across continents, optimized packaging helps reduce emissions per unit.

We also supply printed manuals, hangtags, and a wide variety of labels – including hologram stickers, removable warning labels, and multi-purpose sticker sheets.
For customers handling final product finishing in-house, we produce high-quality water transfer decals and other branding components aligned with their design language and surface materials.

Our experience extends to a wide range of accessory and performance-critical components – from grips, bar tapes, and end caps to brake pads that rank among the best in independent comparison tests.

We produce injection-molded parts in a variety of materials, including fiber-reinforced plastics (short- and long-fiber carbon or glass), as well as rubber components such as frame protectors and crank arm boots.

Compression-molded carbon parts – including seatpost clamps and brake levers – are developed in-house or based on customer specifications.

We also support the production of:
• cast components using lost mold techniques (e.g. pedal cleats),
• phenolic resin parts,
• and thermoplastic elastomers.

For OEMs with specific finish or tactile requirements, we offer overmolding, soft-touch coatings, and custom color matching – both decorative and functional.

We support the production of mechanical and thermal components for electronic assemblies – including heatsinks, PCIe brackets, and ruggedized housings.

Frederik “Ed” Kuehl – Founder – Product Development & Manufacturing Strategy

Ed is a German engineer whose connection to the bike world began in the early 1990s – not in an office, but on the trail. He grew up during the golden era of mountain biking, when innovation was driven by small builders and boutique brands – long before the rise of mass production.

Following his passion for mechanics and materials, he trained as an industrial mechanic at GROB, a world-leading manufacturer of special-purpose machine tools for the automotive industry. There, he developed hands-on expertise in metal cutting technologies – from manual machining to NC and CNC – as well as welding and material behavior.

In 1998, he got his first industry exposure working at the Eurobike booth of Intense Cycles, followed by a visit to the headquarters of Intense and Mountain Cycle in California. These early encounters sparked a lasting connection to the technical side of the industry.

In 2001, Ed launched his own bike brand, Proceed, and began developing frames and components professionally. Around the same time, he became part of the Vertriders in Innsbruck – a group known for their alpine, technically demanding freeride style. He regularly rode and tested with editors from German magazines like BIKE and MountainBIKE, gaining practical insights into product performance and feedback culture.

From 2003, he spent growing parts of the year in Taiwan, supporting production and engineering projects on-site. His technical understanding and direct communication style led to long-term collaborations – often initiated by international brands seeking reliable support on the ground.

After working as project lead for the suspension fork production launch at DT Swiss in Switzerland, Ed returned to Taiwan in 2008, where he continued to lead suspension projects until 2011. That same year, he founded ADG Technology in Taichung – combining European engineering depth with close, local collaboration.

Ed is fluent in Mandarin and works at eye level with local teams – both professionally and culturally. He manages key projects and aligns development and production with technical precision and long-term thinking.

Outside of work, Ed remains connected to what started it all: mountain biking, alpine hiking and mountaineering, and exploring remote landscapes by packraft.

At the heart of ADG Technology is a small, experienced core team – combining technical depth, global industry background, and a shared mindset shaped by sport, engineering, and long-term collaboration. Around this core, we work with a trusted network of specialists, manufacturing partners, and engineering collaborators to scale our capabilities when needed.

Clement serves as our technical lead and a key link between design and production. Before joining ADG Technology in 2013, he worked for Taiwan’s leading CNC machining equipment manufacturer and later became head of the Asian service center for DT Swiss. His understanding of precision manufacturing and supplier alignment is central to our operations. As a triathlete, marathon runner, and mountaineer, he applies the same discipline to every project he touches.

Nina joined ADG Technology in 2014 and became the backbone of our daily coordination. With previous experience at Nike’s Asia Sourcing Headquarters, she brought a solid foundation in international purchasing and supplier management. At ADG Technology, she ensures structure, transparency, and smooth workflows – especially when things get complex or time-sensitive.

Alongside Meiling – who ensures that our financials and internal organization run smoothly – and Ed as founder and technical strategist, our core team ensures alignment, reliability, and technical clarity across all projects. Most of us have worked together for over a decade.

Whether in product development, operations, or supplier interaction – we maintain short paths, direct responsibility, and a clear understanding of both the technical and human side of manufacturing.
And beyond the job, you’ll still find many of us on the trail, in the mountains, or in the saddle.

In addition to our core team, we work with a trusted network of professionals who contribute specialized expertise across engineering, manufacturing, quality, and finance.

Depending on the scope of the project, we collaborate closely with field engineers, process specialists, and technical liaisons embedded in key production facilities. This gives us direct access to know-how in areas like tooling, surface treatment, sealing systems, and composite processing.

We also benefit from experienced support in accounting and commercial coordination – particularly from partners who are familiar with the requirements of high-volume international clients.

This extended team allows us to scale with confidence, maintain technical alignment, and ensure smooth execution – even in complex, multi-layered projects.
