This titanium seatpost repair hardware range covers multiple bolt and nut formats used on selected performance road-bike seatpost assemblies. The source listing includes M5, M6, and M7 configurations for Specialized Tarmac SL8 / SL9, Giant TCR and Propel, Darimo seatposts, Pinarello applications, and other compatible seatpost systems using the same dimensions.
The listed material is Grade 5 / TC4 Ti-6Al-4V titanium. The source product data also identifies CNC machining and anodized finish options. Because this product contains several different head styles and dimensions, the selected variant should be matched to the original seatpost hardware rather than chosen only by thread diameter.
Available configurations
- Thread sizes: M5, M6 and M7
- M5 examples: 8.5 × 15.5mm and 8 × 13.5mm
- M6 examples: 9 × 18mm, 10 × 20mm, 10 × 14mm, 10 × 13mm, 6 × 30mm, 6 × 35mm and 6 × 40mm
- M7 examples: 10 × 20mm and 7 × 35mm
- Head styles: cylindrical, conical, flanged and raised conical nut configurations
- Colors: options include Gold, Rainbow, Black, Titanium Silver, Candy, Blue and Purple where offered
Fitment notes
Seatpost bolts can differ in thread size, overall dimensions, head geometry, washer arrangement and nut shape even when they are used on similar frames. Compare the selected option with the original hardware before installation. Full-set variants for Giant TCR / Propel are also listed separately from individual replacement bolts.
If your exact frame, seatpost generation or original bolt dimensions are not shown in the available options, verify compatibility before ordering.
