Founded in May 2023, the club brings enthusiasts together through in-person gatherings, collaborations with brands and manufacturers, and a digital platform designed to offer a secure space for discussion beyond social media such as Instagram.

Membership is by application, reflecting the club’s focus on safety at events and on keeping member information and partner benefits private. Members can access selected exclusive offers, including partner discounts and vouchers, as well as a monthly online meet-up. Most in-person events currently take place in the wider North Rhine-Westphalia area, with plans to expand their reach over time. The club also runs a shop offering kaliber merchandise and other products that let members take the club spirit with them. Annual membership costs €120, helping fund the platform and its offerings, while events are intended to remain free wherever possible.
