FEATURES

Engraved head tube logo
We etch our classic logo directly onto the head tube, so your grandchildren will know the frame you pass down to them is a Van Nicholas.

Polished finish high lust
Our high lust finish is achieved the old-fashioned way, with a liberal application of elbow grease.

Hydroformed frame tubing
Hydroforming allows us to optimise the structural rigidity of a smaller gauge of metal, so the only thing lost is weight, not performance.

Lifetime frame warranty
Titanium wont rust, corrode, or break down. We are extremely proud of our products. This is why we guarantee our frames for life.

H-bridge increased stiffness
Placing an H-shaped bridge between the chain stays increases frame stiffness in one of the areas where you need it most.

3D sculpted dropout
We designed our dropout from every angle to ensure maximum efficiency at one of the highest-strain contact points of the frame.
