M5 Titanium Caliper Bolts for Shimano Flat Mount - R9270 / R8170 / R8070 / R7170

Short Description

High-performance Grade 5 titanium bolts engineered for Shimano flat-mount road systems. Precision-machined for significant weight reduction and uncompromising clamping security across all riding conditions.

🔧Product Description

The S-PARTS M5 Titanium Caliper Bolts are the ultimate hardware upgrade for performance-driven road cyclists. Specifically designed for the Shimano Flat Mount standard (including Dura-Ace R9270 and Ultegra R8170/R8070), these bolts replace heavy standard OEM hardware with aerospace-grade Ti-6Al-4V.

S-PARTS combines technical precision with cycling aesthetics, ensuring your calipers stay perfectly aligned while adding a premium, custom finish to your build.

• Notice: Some screws may have 'white lines' on the threads, which is a normal result of the coloring process. Rest assured, they are safe to use.

✨ Advanced Surface Craftsmanship

To achieve vibrant aesthetics and long-term durability, we utilize two distinct high-end coloring processes:

• PVD Vacuum Nitriding (Gold / Black / Blue / Rainbow): A molecular-level coating process that creates an ultra-hard, scratch-resistant surface with a high-gloss finish.
• Anodic Oxidation (Purple / Green / Candy / Indigo): An electrolytic process that produces rich, saturated hues while preserving the natural metallic texture of the titanium.

🚀 Why S-PARTS Titanium?

• Significant Weight Reduction: Substantially lighter than standard OEM steel bolts (exact weight savings vary by bolt length).
• Extreme Fatigue Resistance: Designed to withstand repeated thermal expansion and vibration under heavy braking loads.
• T25 Torx Drive: Features a precision T25 interface for superior tool engagement, significantly reducing the risk of bolt stripping compared to standard hex drives.
• All-Weather Durability: Naturally 100% rust-proof and resistant to road salt, sweat, and corrosion.

🔩 Compatibility & Fitmen

• Shimano Road: R9270, R8170, R8070, R7170, R7070.
• Other Systems: Compatible with any Flat Mount caliper or adapter requiring M5 mounting bolts.
• Important: Please measure your frame or fork thickness carefully. Ensure the bolt length provides sufficient thread engagement according to your frame manufacturer's requirements.

💡 Pro Tip

Always use a calibrated torque wrench for installation to ensure safety and performance. Please follow the official torque specifications provided by Shimano and your frame manufacturer for your specific setup (commonly around 6–8 Nm depending on application). We recommend applying a small amount of anti-seize or assembly paste to the threads before installation.
