The two bolts clamping your brake hose into each Shimano shifter weigh 9.6g per pair — identical steel across Dura-Ace R9270, Ultegra R8170, and 105 R7170. Titanium replacements drop that to 4.0g, the single largest bolt-pair savings in the 12-speed lineup at 5.6g per shifter. Covers ideal swap timing during brake bleed, one-bolt-at-a-time method to avoid re-bleeding, and grease-on-threads practice for titanium in aluminum lever bodies.

Shimano doesn't publish pulley bolt weights — here are the actual numbers. R9270 Dura-Ace: 2.6g per pair. R8170 Ultegra and R7170 105: 4.0g per pair. Titanium replacements drop to 1.0g across all three, saving up to 3g (75% on Ultegra/105). Covers galling prevention for Ti threads in aluminum cage plates and why a pulley swap is the ideal moment to upgrade the bolts.

TiNE titanium opposed-lock chainring bolt pair: 2.0g versus roughly 10-12g steel per pair. Five pairs on a standard 110 BCD spider total 10g, saving roughly 40-50g from the rotating assembly. Double-sided hex design places a socket on both bolt head and nut — two 5mm Allen keys work opposite each other for clean torque. Bolt M8 × 6mm thread, nut 7mm thread length. Grade 5 Ti-6Al-4V, CNC machined, 8-color anodized finish. Torque in star pattern to roughly 5-8 Nm.

TiNE titanium bar end plugs replace stock plastic plugs with topology-optimized Grade 5 Ti-6Al-4V. 3g per pair, hex-star cutout lattice design removes material from non-load zones for lighter and stiffer plug. Fits roughly 19mm inner bar diameter — the common drop bar standard. Friction-fit installation: no adhesive, no expanding wedge. 8-color anodized finish. Pull out with pliers when re-wrapping bar tape.

TiNE titanium shifter clamp band replacement for SRAM and Shimano groupsets. Single band 4.8g, pair 9.6g. Weight savings: ~22.8g vs SRAM Red pair (~32.4g), ~24.2g vs Shimano 8170/7170, ~12g vs Shimano 9270. V-profile clamp design spreads force across wider contact arc, reducing carbon bar hot spots. Curved inner face CNC-matched to bar diameter. No anodizing for precision clamp face tolerance. Grade 5 Ti-6Al-4V.

TiNE seatpost clamp head tuning set replaces the stock steel clamp with 2 titanium bolts, 1 carbon fiber base, and 2 7075 aluminum arms. Ten frame-specific platforms: V5RS/Y1RS (20.8g, saves 45.2g), Cervelo S5 (21.4g, 40.4g), Colnago (20.3g, ~62.8g), Pinarello 21-24 (22.1g), Pinarello 25 (22.1g), Roval (20.8g), Darimo (17.9g), Exs (19.1g), Quick Pro ER One (22.5g). Grade 5 Ti-6Al-4V bolts, 8-color anodized.

Bike computer mount upgrade: TiNE 3D-printed titanium body weighs 8.8g with 3.8g detachable under-hang bracket (for GoPro/lights). Fits over 30 integrated bar models including Specialized Roval Rapide, Cervelo S5, Colnago Y1RS, Trek Madone SLR. Topology optimization removes material from non-load areas. Grade 5 Ti-6Al-4V, roughly 45% lower density than steel.

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.

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.
