"Unknown SC-1 Green | 4130 Chromoly fixie & Single Speed"

Signature Urban marco — Green Edition

The Unknown SC-1 Green is a tough, confiable fixie built for everyday riding. The deep green finish gives this bike a cool, understated look that works in any setting — from campus to ciudad centre. Built from 4130 chromoly acero, the SC-1 is engineered to handle the daily demands of urban commuting while staying comfortable on longer rides. At 9.4kg in tamaño M, it is one of the lightest acero fixies in its class.

Built to Last

Chromoly acero is prized for its strength and natural vibration dampening — it gives you a noticeably smoother ride than aluminio on rough ciudad roads. The acero horquilla complements the marco with stable, predictable handling you can trust in traffic. The sealed-bearing Mushroom buje conjunto de ruedas with Japanese bearings ensures effortless rolling ride after ride.

Ride Fixed or Single Speed

The SC-1 comes with a flip flop buje, giving you the freedom to ride fixed gear or flip the rear rueda for single speed. Great if you are just getting into fixed gear riding and want the option to coast, or if you like switching between the two. The 46t/17t gearing is well suited for flat ciudad riding.
