Product Introduction
Many riders struggle with unnecessary weight, corrosion in wet conditions, and torque uncertainty when assembling premium bicycles. The Lightweight Titanium Screw for Bicycles addresses these issues by combining significant weight savings, excellent corrosion resistance, and clear torque guidelines for both aluminum and carbon fiber components. Built from aerospace-grade titanium alloy, it's engineered for professional cycling teams and high-end enthusiasts alike. We recommend it for those seeking a durable, precision-fit fastener without compromising aesthetics.

Product Features & Application
■ Precision Efficiency
Thread concentricity ≤0.02mm, verified by CMM inspection, ensures even load transfer and minimizes fatigue cracking.
■ Corrosion Resistance
Salt spray resistance ≥2000h (ISO 9227) means zero rust after 3000km coastal racing conditions.
■ Lightweight Advantage
Up to 47% lighter than stainless steel, reducing total bike weight by over 200g in full bolt replacement scenarios.
■ Professional Cycling Applications
The Lightweight Titanium Screw for Bicycles is widely used in professional road racing bikes, mountain bikes, and custom builds requiring high torque stability and low galvanic corrosion with carbon or aluminum frames.
Product Details

FAQ
Q1: How should I install these screws on carbon fiber parts?
A1: For carbon fiber assemblies, the goal is to secure the joint without crushing the laminate. Use a torque wrench checked within ±3% accuracy, set to the values in our chart, and apply a thin layer of titanium-grade anti-seize (e.g., MoS₂-based). Avoid "hand-feel" tightening, and inspect the clamping area after the first ride to confirm there's no compression marking.
Q2: Are they suitable for marine or coastal riding?
A2: Yes, provided post-ride rinsing is performed. Corrosion rate in 3.5% NaCl is only 0.008 mm/year, but prolonged salt accumulation may stain anodized surfaces.
Q3: What's the service life?
A3: Under typical cycling loads, titanium fasteners can last over 8 years. We provide a free "lifetime estimator" tool using the formula lifetime (hours) = 15,000 ÷ current density.
Q4: Can I get custom colors?
A4: Yes, anodizing per MIL-A-8625 Type II allows full RAL color matching. Minimum order applies for custom finishes.
Q:5: How do they compare to aluminum bolts?
A5: In side-by-side bench testing, Grade 5 titanium fasteners held load cycles roughly twice as long as 7075 aluminum bolts before fatigue failure. They also maintain joint stability when used with carbon or aluminum frames, as titanium's electrochemical potential is much closer to these materials-reducing galvanic corrosion risk in wet or coastal use.
