Specialized Tarmac seatpost clamp head opposed-lock bolt upgrade with TiNE titanium. One bolt + one nut pair: 7.1g versus roughly 19.5g stock, saving roughly 12.4g. Opposed-lock design threads bolt and nut from both sides of the clamp head for even saddle rail pressure. Fits SL6/SL7/SL8 direct-head seatposts. Grade 5 Ti-6Al-4V, CNC-machined, eight anodized colors. Torque roughly 4-6 Nm.

Headset top cap upgrade with TiNE topology-optimized titanium. Five fit-specific versions: universal round 4.2g, Specialized Tarmac SL8/SL9 6.0g, EXS Aerover 9.0g, Pinarello My25 8.2g, Pinarello 2021-2024 7.5g. Bionic sculpted surface removes material from non-load zones. Step-by-step installation: identify frame standard → remove stock cap → place TiNE cap → torque preload ~1-2 Nm. Grade 5 Ti-6Al-4V, roughly 45% lighter density than steel.

Titanium bicycle bolts swap steel piece by piece: stem faceplate M6×25-45 (2.0-3.3g each), SL8/SL9 seatpost clamp (4.4g vs 12.5g, saves ~8.1g), disc brake mount (5.9g vs 14.2g, saves ~8.3g), Shimano derailleur pivot (2.0g vs 8.4g, saves ~6.4g). Full bike saves roughly 40-100g. Grade 5 Ti-6Al-4V, CNC, 8 anodized colors.

Flat-mount brake caliper mounting bolt hides inside the fork leg — stock steel weighs 14.2g on SL8/S5. TiNE titanium disc mount drops to 5.9g (saves ~8.3g), with sunken bolt head flush to fork surface. Universal flat-mount version at 7.5g. Grade 5 Ti-6Al-4V, CNC machined, 8 anodized colors. Compatible with SL8/S5/S9.

Tarmac SL9 seatpost clamp is SL8-compatible — same wedge-style binder, 6.5mm pitch, 6-8 Nm torque. TiNE SL8/SL9 clamp weighs 4.4g vs stock 12.5g steel, saving roughly 8.1g. Part of a full titanium upgrade pattern: stem bolts, disc mount, bottle hardware. Grade 5 Ti-6Al-4V, CNC, 8 anodized colors.

Tarmac SL9 refines SL8 with same BSA bottom bracket and compatible interfaces. TiNE SL8 upgrades fit directly: seatpost clamp (4.4g vs 12.5g, saves ~8.1g), SL8/S5 disc brake mount (5.9g vs 14.2g, saves ~8.3g), computer mount (8.8g body + 3.8g under-hang, replaces 30-50g), M6×25-45 stem cap bolts (2.0-3.3g each). All Grade 5 Ti-6Al-4V, CNC, 8 colors.

Titanium bolt kit replaces every Shimano drivetrain fastener (26 positions). Three versions: 105 R7170 (TiNE 68.9g vs stock 177.3g, saves ~108.4g), Ultegra R8170 (59.3g vs 148.5g, saves ~89.2g), Dura-Ace R9270 (59.3g vs 113.7g, saves ~54.4g). 105 biggest savings; Dura-Ace best for corrosion resistance. Grade 5 Ti-6Al-4V, CNC, 8 colors.

Centerlock-to-six-bolt adapter converts six-bolt rotors to centerlock hubs. TiNE titanium lock rings: outer 5.5g (for six-bolt conversion), inner 4.6g (for direct centerlock), roughly half the weight of steel (~10-12g). Step-by-step install guide covering hub identification, lock ring selection, and spline thread care.

Flush mount bolts appear on stem face plates, derailleur hangers, and seat clamp collars. Steel bolts tend to seize in aluminum. TiNE Grade 5 Ti-6Al-4V stem bolts (2.0-3.3g each) resist seizing far better than steel. M5 hanger bolt upgrade also available. 8 anodized colors.
