Urban track bike with "just the right amount of room" for everyday use in urban areas
Following RETROTEC's 1×1 style MTB , we asked Jeremy Sisip, builder of SYCIP DESIGN , to design an urban track bike as the "third model" based on CIRCLE'S BOSS's own prejudice. If the RETROTEC model was a bike to be "used up" in off-road riding, this one was designed to be "a bike that can be stepped on firmly and bring quiet satisfaction" on asphalt, at traffic lights, on hills, and in the hustle and bustle.
What we asked for was a simple track bike with no gear shifting and no decoration. A bike with the street sensibility of a Surly Steamroller, but a little more subtle, a little more gentle, and a little more in tune with "what I'm feeling right now. It is a product that is a little more subtle, a little more gentle, and a little more in tune with the "mood of the moment. It seemed only natural that Jeremy Sisip, with the best welding skills in California, would be able to bring this to life.
The design of this bike, which is designed to accommodate up to 35c tires and can be fitted with fenders, is ideal for everyday use in the city.
The colors are based on the coloring that existed in the past, but updated with the genuine Porsche colors of the 70's, paying homage to the Steamroller. PORSCHE GREY has the depth that the Porsche of yesteryear wore that cannot be described.
