Signature Urban marco — White Edition
The Unknown SC-1 White is a tough, confiable fixie built for everyday riding. The clean white finish gives this bike a fresh, minimal look that pairs with anything — a timeless colourway that never gets old. Built from 4130 chromoly acero, the SC-1 is built to survive the daily grind of ciudad commuting while keeping you comfortable on every ride. At 9.4kg in tamaño M, it is one of the lightest acero fixies in its class.
Built to Last
Chromoly acero is the go-to material for frames that need to be strong and comfortable — it naturally absorbs road vibration, giving you a smoother ride than aluminio over rough ciudad surfaces. The acero horquilla complements the marco with steady, predictable handling you can rely on in busy traffic. The sealed-bearing Mushroom buje conjunto de ruedas with Japanese bearings rolls effortlessly every time.
Ride Fixed or Single Speed
The SC-1 comes with a flip flop buje, letting you ride fixed gear or flip the rear rueda to switch to single speed. Perfect for beginners who want the option to coast while learning, or seasoned riders who like having both setups on one bike. The 46t/17t gearing is well suited for flat urban riding.
