Steel Tips

Steel rewards attention.

Not just in how a bicycle is built, but in how it is chosen, fitted, and lived with over time. This page is a small collection of practical notes from our workshop — drawn from decades of building, riding, and listening to riders. No trends, no shortcuts. Just what we've learned, shared openly.

Why steel

Steel is the material that taught us patience. It can be shaped to a rider's exact geometry, repaired decades later, and rewards a careful hand more than any other frame material. A ZULLO is not a season's bicycle — it is the bicycle you will ride into your seventies.

Choosing your geometry

A made-to-measure frame begins with you. Height, inseam, arm length, riding intent — every measurement informs how the frame is composed. We translate body and habit into proportion, and proportion into a bicycle that disappears beneath you.

Caring for your frame

Steel asks for little: a dry cloth after wet rides, a touch of frame-saver inside the tubes every few years, and the same chain hygiene you'd give any good bicycle. Treated with care, your ZULLO will outlast its first three groupsets.
