980g Carbon Gravel Frame Case Study: German Race Brand & Nordic MTB Project

When a German racing brand approached us with a challenge—build a sub-1000g UCI-legal gravel frame with EN Gravity certification for the EU market—we knew this was the kind of project that separates experienced carbon frame manufacturers from the rest. This case study breaks down exactly how we delivered a 980g Toray T1000 frame, passed all eight EFBE Gravity tests, and helped our partner launch at Eurobike 2025 with over 200 frames sold in the first quarter.

Behind every successful carbon frame launch is a story of material selection, geometry refinement, and relentless testing. We’re pulling back the curtain on two real-world projects that showcase what’s possible when you work with an OEM manufacturer that’s been in the carbon fiber game since 2007.

The Challenge: Sub-1000g Gravel Frame with EN Certification

The German race brand had a clear brief. Their pro team needed a gravel frame that weighed under 1000 grams—competitive at the highest level of gravel racing—but it also had to pass EN Gravity certification to sell legally across European markets. That combination of ultralight weight and regulatory compliance is where most manufacturers stumble.

Here’s why: achieving sub-1000g weight typically means cutting material thickness or using exotic layup schedules that compromise structural integrity. EN Gravity testing (specifically the EFBE protocol) subjects frames to eight separate load tests, including frontal impact, fatigue cycling, and static overload scenarios. A frame that’s too thin in the wrong places will crack under test conditions.

The brand had already been turned down by two other factories. One couldn’t hit the weight target. The other couldn’t guarantee EN compliance. We took a different approach.

Material Selection: Why Toray T1000 Made the Difference

We specified Toray T1000 carbon fiber for the main triangle, which offers a tensile strength of approximately 3,530 MPa and a modulus of 294 GPa. For context, T1000 sits in the upper tier of aerospace-grade carbon—significantly stiffer and stronger than the T700 or T800 grades that dominate the mid-range frame market.

But raw material grade is only half the story. The layup schedule—how many layers go where, at what orientation—determines the final ride quality and durability. Our engineering team ran finite element analysis (FEA) simulations on the proposed geometry, identifying stress concentration zones around the head tube junction, bottom bracket shell, and seat tube-to-chainstay bridge.

We used a variable-thickness layup: 6-8 plies in high-stress areas, tapering to 3-4 plies in the mid-tubes. This approach, sometimes called “selective reinforcement,” keeps the frame weight at 980 grams while maintaining structural margins that comfortably exceed EN test thresholds.

Riders looking for similarly engineered road bike frames can explore our full range, which uses the same material philosophy applied to different riding disciplines.

Custom Race Geometry: Fitting the Pro Team

Geometry is where custom OEM work really pays off. The German brand’s pro riders had specific fit data from their bike fitters—stack, reach, and saddle setback numbers that needed to translate directly into frame dimensions.

We developed a race geometry with a slightly longer reach (390mm on a size 54) and a lower stack (545mm) compared to typical gravel endurance geometries. The head tube angle was set at 71.5 degrees with a 70mm trail figure, giving the bike quick handling on technical gravel descents while maintaining stability at speed on paved transitions.

Chainstay length was kept tight at 425mm—aggressive for a gravel frame, but the pro team wanted responsive acceleration out of corners. We accommodated this with a dropped drive-side chainstay design that still clears 45mm tires with adequate mud clearance.

This kind of geometry customization is what separates a generic catalog frame from something that genuinely performs at the professional level. If you’re exploring options for a gravel bike frame build, we can tailor geometry to your exact specifications.

Testing and Certification: Passing All 8 EFBE Gravity Tests

EN 17406 (the current standard for gravel/all-road frames, tested under EFBE Gravity protocol) requires frames to survive eight distinct test scenarios:

• Frontal impact test — simulating a head-on collision with a fixed obstacle
• Falling mass test — a 22.5 kg weight dropped from specified heights onto the frame
• Vertical fatigue test — repeated loading cycles at the bottom bracket
• Horizontal fatigue test — simulating rider weight distribution under braking
• Pedal fatigue test — cyclic loading through the crank interface
• Static overload test — applying 2.5x maximum rider weight without failure
• Fork retention test — verifying the head tube assembly integrity
• Drop test — simulating a crash scenario from riding height

Our 980g T1000 frame passed every test on the first submission. The critical factor was the reinforced head tube junction—we added two additional bias-ply layers at 45 degrees around the head tube gusset area, which distributed impact forces across a wider carbon surface rather than concentrating stress at a single point.

This is where our 15+ years of carbon frame manufacturing experience shows. We’ve submitted hundreds of frames for EN testing over the years, and we’ve learned exactly where frames fail and how to prevent it. Newer factories often learn these lessons the expensive way—through failed tests and costly retooling.

From Prototype to Eurobike: The 6-Month Timeline

Speed to market matters in the cycling industry. The brand’s goal was to showcase the finished frame at Eurobike 2025, which gave us a six-month window from initial design brief to production-ready frames.

Here’s how that timeline broke down:

• Weeks 1-3: Geometry finalization and FEA simulation
• Weeks 4-8: First prototype layup and molding
• Weeks 9-11: Prototype testing and geometry refinements
• Weeks 12-16: Second prototype, EN testing submission
• Weeks 17-22: Production tooling and first batch run
• Weeks 23-26: Quality control, finishing, and shipping

The brand launched at Eurobike with production frames on display and demo bikes available for test rides. They took 200+ frame orders in the first quarter post-launch—a strong result for a niche gravel racing product competing against established brands like Canyon, Cervélo, and 3T.

Their competitive advantage was clear: a 980g frame with EN certification and pro-level geometry at a price point roughly 40% below comparable offerings from European-assembled brands.

Case Study Two: Nordic MTB Frame at 40% Cost Savings

Not every project targets the ultralight segment. A Nordic distributor came to us with a different challenge: they needed a competitive carbon hardtail MTB frame that could take market share from major brands in Sweden, Norway, and Finland—markets where consumers are quality-conscious but increasingly price-aware.

The Nordic Market Opportunity

The Nordic countries have a strong mountain biking culture, with riders who demand frames that handle technical singletrack, rocky terrain, and variable weather conditions. The distributor identified a gap: premium carbon hardtail frames from brands like Trek, Specialized, and Scott were retailing at €1,800-€2,500 for the frameset alone. They believed a well-made alternative at €1,000-€1,200 could capture significant market share.

Development: T800 Carbon with Nordic-Optimized Geometry

We developed a 1,150g Toray T800 carbon hardtail frame. While T800 is a step below T1000 in tensile strength, it offers an excellent balance of performance and cost—a practical choice for a product targeting the value segment rather than the pro racing market.

The geometry was specifically tuned for Nordic conditions: slightly longer wheelbase for stability on root-covered trails, a 67-degree head angle for confident descending on loose-over-hard terrain, and clearance for 29×2.4″ tires. We also added internal routing for a dropper post, which has become nearly mandatory for modern hardtail builds.

The frames were finished with a matte clear-coat over raw carbon weave—popular in the Nordic market where riders appreciate the industrial aesthetic—and came with a threaded T47 bottom bracket shell, avoiding the press-fit headaches that plague many carbon frames.

Results: 500+ Frames in Year One

The distributor launched with a direct-to-consumer model, bypassing traditional dealer margins and passing savings to customers. They ordered 500 frames in the first year and came back for repeat orders before the year was out. Customer feedback highlighted the frame’s ride quality, clean finishing, and the threaded BB as standout features.

For the distributor, the math was straightforward: by manufacturing with us in Huizhou, they achieved a 40% cost reduction compared to sourcing similar frames through European or North American brokers. That margin difference funded their marketing, improved their customer service offering, and still delivered healthy profit per unit.

If you’re interested in exploring similar ultralight carbon frame options—including our ST-09 model at 680g—our product line covers everything from race-focused road frames to versatile gravel and MTB platforms.

What These Case Studies Tell Us About Carbon Frame Manufacturing

Both projects succeeded for the same core reasons:

• Material expertise: Choosing the right carbon grade for the application, not just defaulting to the most expensive option
• Geometry precision: Using rider data and terrain analysis to create purpose-built designs rather than generic templates
• Testing rigor: Investing in proper certification and testing protocols before going to market
• Timeline discipline: Structured project management that hits deadlines without cutting corners

The carbon frame market has matured significantly since we started in 2007. Back then, most Chinese manufacturers were producing generic open-mold designs with little customization. Today, the best factories—including ours—offer full-service OEM capabilities: custom geometry, proprietary layup schedules, color and finish options, packaging design, and certification support.

The competitive landscape rewards brands that can differentiate through product quality and speed to market. Working with an established manufacturer eliminates the guesswork, reduces iteration cycles, and gives you access to manufacturing knowledge that takes decades to accumulate.
