Water Bottle Cage Bolts Weight: Steel vs Titanium M5 Bolt-by-Bolt

TiNEtech

16 jul 2026

Most road bikes carry two bottle cages — that means four M5 bolts holding them to the frame. Steel M5×10 and M5×14 bolts weigh roughly 1.5–2 g each, adding up to 6–8 g across both cages. It sounds small, but on a weight-obsessed road bike, every gram at the frame level counts.

TiNE titanium water bottle cage bolts: M5×10 at 0.7 g and M5×14 at 0.8 g per bolt. Four bolts total roughly 3 g — roughly half the weight of stock steel hardware, with no strength compromise for cage retention.

Stock vs Titanium: Bolt-by-Bolt

Bolt	Stock Steel	TiNE Titanium	Saved
M5×10 (×2)	~1.5 g each	0.7 g each	~0.8 g each
M5×14 (×2)	~2.0 g each	0.8 g each	~1.2 g each

Per-Bike Total (4 bolts) ~3 g titanium vs ~6–8 g stock · Roughly 3–5 g saved across both cages

Why Titanium Works Here

Water bottle cage bolts carry no dynamic load — they only hold the cage against the frame under static compression. Titanium's roughly 40% lower density compared to steel makes it a natural fit: the bolt clamps just as firmly, but weighs far less. The M5 thread diameter provides plenty of grip surface, and Grade 5 Ti-6Al-4V offers roughly 900 MPa tensile strength — well above what a cage bolt requires.

Practical Tip: TiNE bolts come in 8 anodized colors. Match the gold or blue anodized finish to your frame accents for a cohesive look — or go with silver for a stealth swap that most riders will never notice.
