Product Description

Replace the pivot bolt on your Giant Propel rim brake caliper (brake arm pivot) with this S-PARTS Grade 5 Titanium (Ti-6Al-4V) bolt. M6×27mm, 4.23 g per bolt, installs with a T30 Torx wrench, at about half the weight of comparable steel hardware.

Key Specifications

Grade 5 Titanium: High Strength, Low Weight

S-PARTS Grade 5 Titanium has an average tensile strength above 1,050 MPa, well beyond the 895 MPa industry reference. Under equivalent conditions, its overall mechanical performance matches Grade 10.9 steel fasteners at roughly half the weight.

Civilian Aerospace Supply Chain

S-PARTS sources its titanium through a metal raw-material supply chain serving the civilian aerospace industry in Xi'an, China. Each material is selected through long-term laboratory comparison testing to meet the S-PARTS S-Grade standard.

Precision CNC Machining

S-PARTS fasteners are machined in the brand's own factory on military-grade precision CNC equipment. Micron-level tolerance control delivers clean thread engagement and reliable performance.

Color & Finish Options

PVD Nitride Coating: Gold, Rainbow, Black, Blue
A dense metal nitride film forms on the surface, increasing surface hardness and impact resistance. The color goes deep into the surface layer, so it holds up under normal wear and stands up to rain and mud. Heavy abrasion can still wear the coating.

Anodizing: Green, Purple, Candy
Electrolytic oxidation builds an oxide layer on the titanium that increases surface hardness and corrosion resistance. The colors come from light interference within the oxide layer, with no dyes used.

Titanium: Available as a color option alongside the finishes above.

Finish Notes

Candy: Due to the coloring process, the Candy finish has a naturally flowing, semi-random color pattern, so no two bolts look exactly alike.

Thread appearance: Fine white lines may appear near the threads on colored bolts. This is a normal result of the coloring process and does not affect use.

Before You Order

Each order is for one bolt. Add the quantity you need to your cart, and confirm your brake is a Giant Propel rim brake caliper.
