Unknown Singularity Black Chameleon | Fixed Gear & Single Speed Bike

€999.00

The Unknown Singularity Black Chameleon takes the race-proven Singularity platform and wraps it in a stunning black chameleon finish that shifts between dark tones of green, blue, and purple depending on the light. Built around a hardened 6066-T6 aluminum frame with updated track geometry and an integrated aero seatpost, it delivers serious performance at just 7.5kg in size M.

The Singularity is fully equipped with Unknown-designed components for fixed gear and single speed riding. The carbon/alloy fork with 12K carbon blades and aluminum neck gives you sharp, responsive steering and takes the sting out of rough roads. The sealed-bearing Mushroom hub wheelset with Japanese bearings rolls effortlessly, and the 46t/17t gearing is perfectly balanced for city streets and velodrome sessions. The Fix/Free hub lets you switch between fixed gear and single speed depending on your mood.
