A free chain is a fast chain.

Chain lubricants and drivetrain care for riders who refuse to lose a single watt to drag. Matched to the conditions you actually ride in — dry, wet, and the long British in-between.

Fenrir
The Story

Why Fenrir.

A drivetrain should run free. Most don't — held back by old lubricant, grit, and the slow gum of neglect. Power leaves the legs and never reaches the road.

Fenrir exists to close that gap. Each formula is built to flow through the rollers, shed what the road throws at it, and give the chain no reason to slow you down.

Dry, wet, or the long British in-between — there is a Fenrir matched to the conditions you actually ride in, and nothing in it is there by accident.

The Range

Made for the task, not the shelf.

Each Fenrir product is built for one job and judged on how well it does it. Product images drop in here as they are shot.

Bio Chain Lube

Plant-based and built for the wet. Displaces water, clings through the downpour, and breaks down kindly when it finally washes away.
