CuZn is the series production of Quokka cycles, it aims at offering a more affordable option in the line up, with zero compromise on quality.
CuZn frames are handmade in France in the Quokka workshop, using high quality steel tubing from Columbus. Fillet brazed like the bespoked frames, though not filed in order to cut on production time and cost. The raw brazing is a display of our framebuilder’s craft, as without any retouching, the fillets are impeccable.
The first CuZn model to be released is a fixed gear, with a tight geometry and generous tire clearance. Thanks to the full carbon fork we co-developped, it accepts 38mm knobby tires with space for mud.
It is the perfect do-it-all fixed frame from crits, to tracklocross, to street riding.
