AFFINITY Lo Pro Circles Original Complete Bike
AFFINITY CYCLES' signature track bike, characterized by its aggressive sloping top tube
From Brooklyn, New York, the masterpiece from AFFINITY CYCLES: the Lo Pro.
The Lo Pro was born through repeated testing with messengers who ride daily through New York—arguably the world's harshest streets.
For this Circles Original Complete Bike, we have built it up with a parts selection that retains the sharp aesthetic typical of the Lo Pro while making it easy to handle for everyday transportation.
We focused on silver parts to accentuate the beauty of the frame color.
It has been finished as a bike that fits naturally into the city—not too classic, yet not overly race-oriented.
It’s perfect for riding stoically with a fixed gear, or for enjoying a casual ride with a freewheel.
This is the perfect bike for those who want to bring a little extra excitement into their daily commute or city riding.
