GR9 Titanium Road Bike Frame
Baoji Yibaite New Materials Technology Co., Ltd. supplies premium GR9 titanium alloy road bike frames for high-performance cycling, custom frame builders, and boutique bike brands worldwide. Operating from "China Titanium Valley" (Baoji), the company specializes in precision tube manipulation, professional hand-welding, and shipping tailored premium bicycle frames to global customers.
The frames utilize aerospace-grade Grade 9 titanium alloy (Ti-3Al-2.5V), fully complying with ISO 4210 bicycle safety standards and EN 14781 racing bicycle specifications. The material delivers an optimal balance of strength, ductile compliance, and fatigue life - producing the legendary, silky-smooth "titanium ride quality" that aluminum and carbon frames cannot replicate. Each frame is precision TIG-welded, CNC-machined at all interfaces, and stress-relief heat treated to guarantee perfect alignment and long-term dimensional stability. Weighing just 1.3 kg to 1.6 kg for a bare frame, it offers carbon-fiber-level weight with far superior impact resistance and lifetime durability - it will never rust, delaminate, or degrade over decades of use.
Standard road geometries are available in sizes 48 cm to 62 cm, with custom geometry, disc brake mounts, internal cable routing, and thru-axle dropout options available upon request. OEM and ODM customization services are fully supported for bike brands, teams, and distributors.
Products Description
Aerospace-Grade Seamless Titanium Frame Tube
- Base Material: Grade 9 (Ti-3Al-2.5V) titanium alloy
- Tensile Strength: ≥ 620 MPa with excellent elongation and fatigue life
- Frame Weight: 1.3 kg to 1.6 kg (bare frame)
- Delivers all-day ride comfort and sprint-ready stiffness without cracking or fatigue failure over decades of use
Ultimate Strength-to-Weight & Longevity Ratio for Elite Cyclists
- Lightweight Efficiency: Combines steel-like structural compliance and stiffness with a low density of just 4.48 g/cm³, resulting in a frame significantly lighter than steel, while providing far superior fatigue life compared to carbon fiber or aluminum.
- Rider Advantage: Maximizes power transfer per pedal stroke, stabilizes high-speed descending, and prevents frame sagging, making it the perfect investment for premium endurance and competitive road setups.
Professional Hand-Welding & Precision CNC Machining
- Frame Construction: Precision TIG-welded or cold-formed titanium tubing with smooth, blended welds - zero porosity, no undercut, no surface cracking
- CNC-Machined Head Tube, Bottom Bracket Shell & Dropout Interfaces: Guarantees perfect headset fitment, precise BB alignment, and accurate derailleur hanger positioning
- Stress-Relief Heat Treatment: Eliminates residual welding distortion for long-term dimensional stability and consistent ride geometry
Corrosion resistance & lifetime durability
- Forms a dense, self-healing natural TiO₂ passive film that shields the frame from surface corrosion, paint bubbling, and material degradation
- Completely immune to rust, delamination, and structural degradation when exposed to rain, road salt, sweat, and coastal riding environments
- The frame will never corrode, crack from impact fatigue, or lose ride quality over decades - it outlasts aluminum and carbon frames by a wide margin
Full dimensional inspection & ride-quality assurance
- Every frame undergoes 100% alignment verification covering head tube angle, seat tube angle, bottom bracket drop, chainstay length, and wheelbase accuracy
- Dropout alignment checked with precision gauges to ensure perfect wheel fitment and disc brake caliper alignment
- Weld quality inspection: 100% visual check for smooth, consistent weld beads with no porosity, undercut, or cold-lap defects
- Surface finish options: raw brushed titanium, hand-polished mirror finish, bead-blasted matte, or custom anodized/painted color
Certified quality & full material traceability
- Manufactured in our 2,100 m² modern facility in "China Titanium Valley" (Baoji) under strict compliance with ISO 9001 quality management standards and ISO 4210 bicycle safety requirements
- Every frame is accompanied by a full EN 10204 3.1 Material Test Certificate (MTC) confirming traceable chemical composition and mechanical properties of the titanium tubing used
- Optional third-party fatigue testing and impact testing reports available for OEM partners and custom frame building programs
