Signature Urban marco — Black Edition
The Unknown SC-1 Black is a tough, confiable fixie built for everyday riding. The classic all-black finish is clean, stealthy, and goes with everything — a no-nonsense look for riders who let their riding do the talking. Built from 4130 chromoly acero, the SC-1 is made to take the daily punishment of ciudad commuting and keep rolling strong. At 9.4kg in tamaño M, it is one of the lightest acero fixies in its class.
Built to Last
Chromoly acero is trusted for its durability and natural vibration dampening — it delivers a noticeably smoother ride than aluminio frames over bumpy ciudad roads. The acero horquilla provides stable, confident handling that you can count on in heavy traffic. The sealed-bearing Mushroom buje conjunto de ruedas with Japanese bearings keeps you rolling smooth every single ride.
Ride Fixed or Single Speed
The SC-1 comes with a flip flop buje, so you can ride fixed gear or flip the rear rueda to switch to single speed whenever you want. Great for beginners easing into fixed gear, or experienced riders who like having both options on one bike. The 46t/17t gearing is well suited for flat urban riding.
