Rekluse has announced its latest auto-clutch technology, the new EXP 4.0, which has a newly designed base and wedge that offer a more connected feel at the lever and more direct power delivery to the rear wheel.

The updated base material is stronger at high temperatures, and the friction pad has revised oil-flow characteristics for greater durability. The EXP 4.0 technology comes in two of Rekluse’s clutch systems, the RadiusX and the RadiusCX, and an upgrade kit for bikes equipped with the previous-edition EXP 3.0 is also available.
