Both the housing and the lever are milled from solid material at HEL Performance in Exeter (UK) using state-of-the-art CNC machining centers. The housing features a high-quality, modern CERACOTE coating, and the lever is anodized. (CERACOTE coating is also available in many colors as a special order)
The mechanical lever ratio can be easily adjusted to your personal preference using an integrated component. Super fast and convenient.
The newly developed brake lever is mounted to the housing with just a single screw. This makes it very easy and quick to replace the entire unit.
