Description
ABSOLUTE BLACK chainring oval for Brompton crank 130 mm 5 hole | 50 teeth | black
Premium chainring with 50 teeth for the 130 mm bolt circle diameter of the Brompton cranks . Equipped with Narrow Wide tooth profiles, they offer a longer service life than standard chainrings.
The ovalization of the chainring increases performance by varying the drive train and optimizing resistance. When kicking with the legs, the natural strengths and weaknesses are brought into line. This achieves better use of the stronger muscle groups and creates a balance in the weaker muscles on the way to work (less stroke).
