Dark Matter, invisible and formless it's existence can only be theoretically inferred from the effect it has on visible/ordinary matter - that explains this bike and how it creates the compulsion to ride.

The Team at JRI combined many years of experience riding, designing and building track bikes for real world conditions to come up with the Dark Matter, the ultimate street bike. It is the culmination of the lessons learned from every bike we've ever put on the street, primarily for the street.

Track-capable but optimized for the roads of everyone's everyday, the tight but not excessive geometry strikes the perfect balance of handling and comfort so whether you're running to the shop, mashing empty midnight streets or pulling a few g's at the 'drome the only thing the Dark Matter will leave you wanting more of is time in the saddle.

Running our new Pista Wheels - Created to be lightweight and strong. JRIFixed hubs and bladed spokes.
