[Product Description]
KOSO High Speed Pulley Set.
The large diameter pulley with 185mm diameter increases the shifting range by 11% compared to the stock pulley.(Reference value).
By reviewing the performance design, it starts strongly from the beginning.Around the maximum speed, the feeling is as if one gear is increased, and when cruising at high speed, the rotation drops and the ride becomes calm.
As to the pulley unit, the rotation balance is adjusted for each to help reduce vibration and horsepower loss at high RPM.
Air-cooling fins are provided on the side of the main unit for effective cooling.
The material is made of carefully selected silicon aluminum, which is very durable.
The section of bosses are grease filled system and designed in a way that the shifting characteristics will not change even after long hours of riding.
The weight roller and slide piece are also made of carefully selected materials to ensure durability.
KOSO is also particular about their manufacturing methods and ensure the uniformity of their products.
The center spring helps to ensure racing shifting.
