Product Description

Precision Titanium Upgrade for TRP DHR EVO Reservoir Cover

Designed specifically for the TRP DHR EVO brake lever reservoir cover, this ultra-lightweight titanium screw provides a direct-fit, corrosion-resistant replacement for the original steel hardware.

In small-diameter fasteners such as M3 applications, material stability and thread precision are critical. This component is engineered to deliver both.

Advanced Surface Finishing

PVD Coating (Gold, Rainbow, Black, Blue)

Physical Vapor Deposition forms a dense titanium nitride layer bonded to the surface:

• Increased surface hardness
• Improved wear resistance
• Stable metallic finish
• Resistant to environmental exposure

Anodized Finish (Candy, Purple, Green, Indigo)

Electrolytic oxidation forms a controlled oxide layer.
Color is generated through optical light interference — without dyes.

• Enhanced corrosion resistance
• Lightweight protective surface
• Dynamic color shift under varying light conditions

Natural Titanium

Raw titanium finish maintaining its original metallic appearance.

Engineering Performance

Aerospace-Grade Titanium Integrity

Manufactured from premium Ti-6Al-4V titanium with an average tensile strength exceeding 1050 MPa, above the commonly referenced 895 MPa industry baseline.

Optimized Strength-to-Weight Ratio

Delivers mechanical properties comparable to Grade 10.9 steel fasteners while reducing weight by approximately 45-50%.

For precision M3 applications, titanium provides:

• Excellent thread engagement stability
• Reduced risk of corrosion-induced seizure
• High fatigue resistance under repeated thermal cycles
• Long-term durability in wet and humid environments

Important Notes

• Designed specifically for TRP DHR EVO reservoir cover position.
• M3 fasteners require careful torque control — do not overtighten.
• Always follow manufacturer torque specifications.
• Professional installation is recommended for brake components.
