Brompton riders have long been requesting a 7-Speed External Hub upgrade, and we’ve listened!

After months of collaboration and in-depth design discussions with the amazing team at Onyx Racing Products, we’re thrilled to unveil this cutting-edge hub, crafted for exceptional performance and lasting durability.

Our journey began with early design conversations, exchanging technology insights, and fine-tuning the specific needs of various Brompton models (A, C, P & T Lines).

Through countless refinements and unwavering dedication, we’re proud to see this innovative product come to life.

A huge thank you to the Onyx Racing Products team for entrusting us with bringing this vision to life.
