The Story
of Karoo

Project “HX” (the initial internal code name for Karoo) commenced in earnest in the spring of 2015. Our small but close-knit team began a daunting but exciting mission, to develop entirely proprietary hardware and software from scratch, and take Hammerhead to the next level. Our goal was to develop a truly revolutionary product at the intersection of cycling and technology.

Through our blog, we’re telling two stories: one is our retrospective account of how Project HX got off the ground over the past two years, and the other are the latest developments inside Hammerhead as we step ever-closer to releasing Karoo.

We hope you’ll follow along, and we thank you for joining us on this journey.
