The Extralite Titanium Brake Caliper Mounting Bolt Set is engineered specifically for mounting post mount disc brake calipers to compatible mountain bike frames and forks. CNC-machined from Grade 5 titanium (Ti-6Al-4V), these lightweight bolts combine exceptional strength with precision manufacturing for secure, reliable brake installation.
Unlike conventional fasteners, the threads are rolled rather than cut, producing a stronger thread profile with improved fatigue resistance. Available in either a natural titanium finish or a durable black PVD coating, these bolts provide a premium finishing touch for lightweight custom builds.
Precision Titanium Construction
Each bolt is CNC-machined from aerospace-grade titanium before the threads are rolled rather than cut. Thread rolling preserves the grain structure of the material, improving fatigue strength and wear resistance while providing smoother engagement during installation.
Compatibility Notes
Designed for post mount disc brake caliper installations using M6 mounting hardware. Always verify the required bolt length for your frame, fork, brake caliper, and any adapters being used. Tighten only to the brake manufacturer's specified torque value and never exceed the Extralite maximum specification of 7.8 Nm.
Complete Your Build
Pair these bolts with other lightweight Extralite hardware including headset spacers, stem hardware, chainring bolts, derailleur hardware, and additional titanium fasteners to complete a premium lightweight build.
