At 9.4kg in rozmiar M, it is one of the lightest stal fixies in its class.

Built to Last

Chromoly stal is legendary for its toughness and natural flex — it soaks up road vibration better than aluminium, making every ride smoother and more forgiving on rough surfaces. The stal widelec pairs perfectly with the rama for stable, confident handling in miasto traffic. The sealed-bearing Mushroom piasty zestaw kół with Japanese bearings delivers niezawodny, friction-free rolling day in, day out.

Ride Fixed or Single Speed

The SC-1 comes with a flip flop piasty, so you can ride fixed gear or simply flip the rear koło to switch to single speed. Ideal for riders new to fixed gear who want the safety of being able to coast, or for anyone who likes having both options. The 46t/17t gearing is well suited for flat urban riding.
