SRAM RED AXS bolt kit weight breakdown: stock 139g (shifter hose bolts 2g, front brake mount 12g, derailleur pivot 5.2g, crankset bolts 11.2g, plus remaining hardware). TiNE titanium weighs 77.7g total, saving 61.3g. The front flat-mount brake adapter is the single largest saving at 5.5g. Covers step-by-step install sequence and flat-mount vs SL8-specific brake mount options.

Shimano 12-speed groupset bolt kit weight comparison: stock steel weighs 179.3g on 105 R7100, 145.3g on Ultegra R8100, 117.7g on Dura-Ace R9270. TiNE titanium replacement kit weighs 69.9g across all three — the weight gap comes entirely from stock hardware. Covers shifters, calipers, derailleur, and crankset zones with per-item data.

How much does a Shimano rear derailleur pivot bolt weigh? The 105 R7170 uses a thick steel pin at 8.4g — the heaviest single bolt in the entire derailleur and the biggest bolt-saving opportunity at 6.4g with a Grade 5 Ti-6Al-4V replacement (2.0g). Dura-Ace R9270 and Ultegra R8170 already use a lighter 3g bolt; titanium saves an additional 1g. Covers the pivot bolt's structural role (parallelogram main shaft), why Shimano left 105 with the heaviest version, thread prep for titanium in aluminum, and torque notes.

Does the Garmin Edge 1050 need its own mount? At 161g the 1050 is 38% heavier than an 840, and its 3.5-inch screen overhangs standard arms — visible wobble on rough descents. A topology-optimized 3D-printed titanium mount provides a wider arm bed and distributes weight more evenly. Includes a detachable 3.8g GoPro/light under-mount. Covers standard vs 1050-specific arm comparison, lever-arm physics of a heavier head unit, and FAQ on backward compatibility and GoPro/light cage attachment.

Seatpost yoke and saddle clamp assemblies range from 28.9g (Darimo) to 83.1g (Colnago) in stock form. Titanium-and-carbon replacements drop Colnago to 20.3g (62.8g saved), V5RS/Y1RS to 20.8g (45.2g saved), Roval to 20.8g (28.9g saved), and Darimo to 17.9g (11g saved). Covers what's inside a yoke kit (two Ti bolts, carbon base, 7075 Al yokes), sweat corrosion advantages in the drip zone under the saddle, and 10-minute install without changing saddle position.

Crank bolts live inside the spindle — invisible, rarely serviced, and universally steel from the factory. Look/SRM: 15.5g stock vs 11.0g titanium (saves 4.5g). SRAM DUB: 16.1g vs 10.5g (saves 5.6g). THM: weight-neutral swap for material consistency. Covers why Grade 5 titanium handles 35-50 Nm crank bolt torque (tension not shear, taper carries pedaling load), grease practice, and the story of a rider discovering crank bolts as the last overlooked steel hardware category.

The front derailleur spacer and two mounting bolts weigh 4.0g — identical steel across Dura-Ace R9270, Ultegra R8170, and 105 R7170. Titanium replacements drop to 1.8g, saving 2.2g. Covers the swap process (no FD removal needed), and cumulative weight picture with other Shimano hardware upgrades (pulley bolts, limit screws, pivot bolts) totaling 20g+ from groupset hardware alone.

The bolt clamping the brake hose into each Shimano caliper weighs 5.0g per pair — identical steel across R9270, R8170, and R7170. Titanium drops to 2.0g, saving 3g front and rear combined. A three-step guide to locate, swap, and check — no re-bleed needed. Builds on previous caliper hardware swaps for fully titanium brake systems.

The bleed port screws on Shimano flat-mount road calipers weigh 4.6g per pair — identical steel across Dura-Ace R9270, Ultegra R8170, and 105 R7170. Titanium replacements drop to 1.8g, saving 2.8g for both calipers combined. Covers O-ring transfer, shallow aluminum thread engagement and grease practice, low torque values (1–2 Nm), and why the bleed port screw is the last steel part left on a fully titanium-hardware caliper.
