Kinetics Rear Triangle for Brompton - Stainless Steel - Unpainted

These Brompton-compatible rear triangles were designed for Rohloff but are suitable for fitting most standard rear hubs to a Brompton.

The design has been refined over 10 years of making hundreds of Rohloff Bromptons.

Made entirely from 304 marine-grade stainless steel, they won’t rust.

The rear frame has a 135mm OLN width (the Brompton normally is 112mm) so will work with most standard hubs like the Rohloff and Alfine.

IS disc brake mounts and enough space for a 160mm rotor.

They work with normal Brompton frame rollers and Eazy wheels, brakes, and the standard suspension block. Standard L Type mudguards and rear rack will also fit, and if you use a Rohloff it also uses the standard Brompton single-speed tensioner.

Lifetime warranty.
