Specialized SL9 Frame Bolt Kit Titanium 8.3 g vs Stock 19.7 g (11.4 g Saved)

Specialized's Tarmac SL9 ships with a set of frame bolts — seatpost clamp, front derailleur mount, water bottle cage mounts, and headset top cap — totaling 19.7 g in stock steel. TiNE's Grade 5 Ti-6Al-4V replacement kit brings the entire set down to 8.3 g, saving 11.4 g on the frame hardware alone. And because these bolts sit on the frame (not the drivetrain), they stack cleanly with TiNE's Shimano derailleur and hydraulic bolt kits for compounded savings.

SL9 frame bolts + Shimano bolt kits = additive savings. The SL9 frame bolt kit covers the frame-side fasteners (seatpost, FD mount, bottle cages, headset). TiNE's Shimano bolt kits cover the drivetrain and hydraulic side (derailleur bolts, caliper bolts, lever bolts). Because they target completely different bolt positions on the bike, the two kits do not overlap — you can install both for full-bike titanium coverage without any redundancy.

What Makes This Kit SL9-Specific

The SL9 uses a different bolt set from SL7/SL8. The SL9 frame has a dedicated seatpost clamp bolt design, specific front derailleur mounting tabs (M4×2), four water bottle cage bosses (M5×4), and a headset top cap bolt (M3×1). The kit includes exactly these 8 bolts — no extras, no missing positions. Each bolt is CNC machined from Grade 5 Ti-6Al-4V to match the SL9's specific thread depths and lengths.

Stacking with Shimano Bolt Kits

Grade 5 Ti-6Al-4V, CNC machined, 8 anodized colors (gold, blue, rainbow, silver, black, pink, green, multi). 8-bolt kit covers seatpost clamp ×1, FD mount ×2, bottle cage ×4, headset ×1. SL9-specific thread depths and lengths. Stacks with Shimano bolt kits for full-bike titanium coverage with zero overlap.
