The Unknown LV3 Black on Black is our flagship fixed gear bike in a clean, murdered-out all-black finish. No loud colours or flashy graphics — just a stealthy, aggressive look that lets the performance do the talking. Hardened 6066-T6 aluminum frame, track geometry, 8kg in size M.
Under the blacked-out finish sits the same race-grade build that makes the LV3 our most capable bike. The full 12K carbon fork sharpens front-end handling and smooths rough tarmac. Sealed-bearing Mushroom hub wheelset with Japanese bearings delivers friction-free rolling, and the 46t/17t gearing works perfectly whether you are commuting or racing.
