Titanium bolts appear on WorldTour bikes and weight-obsessed builds alike. But what makes them different from steel, and are they worth it? Here are the answers road cyclists ask most.

What Are Titanium Bolts?

Cycling titanium bolts are machined from Grade 5 Ti-6Al-4V — the same alloy used in aerospace and medical implants. At roughly 4.44 g/cm³, it is about 43 % lighter than steel (7.85 g/cm³) with comparable tensile strength, making it the best strength-to-weight option for replacing stock steel fasteners.

Where Do Titanium Bolts Save the Most Weight?

Component	OEM Weight	TiNE Ti	Saved
Shimano 105 R7170 bolt set	177.3 g	68.9 g	108.4 g
Ultegra R8170 bolt set	148.5 g	59.3 g	89.2 g
Dura-Ace R9270 bolt set	113.7 g	59.3 g	54.4 g
Disc brake mount (SL8/S5)	14.2 g	5.9 g	8.3 g
Stem cap bolt (M6 × 25)	—	2.0 g	—
SL8 seatpost clamp	12.5 g	4.4 g	8.1 g

The Shimano 105 R7170 bolt set alone drops 108.4 g — roughly the weight of a CO₂ cartridge. Across a full build, the total approaches 200 g.

Are Titanium Bolts Safe?

Yes — when they match OEM specs. Grade 5 Ti-6Al-4V has tensile strength above 900 MPa, comparable to the steel alloys used in bicycle fasteners. The key is dimensional accuracy: diameter, thread pitch, and length must match exactly. TiNE CNC-machines every bolt to OEM dimensions so the fit is identical to stock. Always tighten with a torque wrench to the manufacturer's specification.

Do Titanium Bolts Corrode?

Grade 5 titanium forms a natural oxide layer that resists corrosion far better than steel — no rust, no seized threads from rain or sweat. Anodized finishes add color and extra surface protection. TiNE offers eight anodized options, from gold to rainbow.
