Titanium Bicycle Bolts Explained

Every bolt on your road bike has a titanium counterpart that weighs roughly half as much. Here is where they go and what you gain.

Stem Cap Bolts

The stem cap bolt secures the top cap and preloads the headset. Stock steel M6 bolts weigh around 6 g. A titanium M6 stem cap bolt from TiNE weighs just 2.0 g (25 mm) to 3.3 g (45 mm) depending on length. Available in M6×25, 30, 35, and 45 mm, they fit most road and gravel stems.

Derailleur Pivot Screws

The rear derailleur pivot screw is one of the easiest weight wins on a bike. The stock Shimano 105 R7170 pivot screw weighs 8.4 g; the TiNE titanium replacement is 2.0 g — a 6.4 g saving from a single screw. Full derailleur bolt kits for Shimano 105, Ultegra, and Dura-Ace save 54 to 108 g depending on the groupset.

Disc Brake Hardware

At the brake, two titanium upgrades stand out. The disc brake caliper mount for Specialized SL8 and S5 drops to 5.9 g versus 14.2 g stock. The Centerlock outer lock ring weighs 5.5 g and the inner cap 4.6 g — both CNC-machined from Grade 5 Ti-6Al-4V with anodized color options.

Shifter Clamp Rings

Shifter clamp rings are often overlooked. A pair of TiNE titanium clamp rings weighs 9.6 g — that is 22.8 g lighter than the SRAM Red equivalent. They are compatible with most drop-bar shifters and add a visible color accent to the cockpit.
