Special Edition: PMC Unpaved


Available by pre-order until Saturday, October 8, 2022.
For each frame purchased, we will donate $250 to PMC Unpaved.

This bike, and those who ride it, are on a mission – to help the Pan-Mass Challenge raise funds for cancer research and treatment at Dana-Farber Cancer Institute.


Lightweight but durable, our Breccia gravel bike can get through anything riders and ride organizers can throw at it. And if the terrain gets tough, it’s easy to pick up and carry across, because as our friend likes to say “in every biker is a built-in hiker.”

The frame can accommodate all the gear you want/need including fenders, fat tires, frame bags (for snacks, don’t forget to bring plenty of snacks) and hydration.

And, like all Ruckus frames, we stuck with a design that is easily built and serviced – no proprietary parts to keep you off the roads, trails or whatever.
