What Kolossos Does for You
First, imagine the performance of replacing your stock pulleys with a ceramic 12-tooth top pulley and a 19-tooth bottom pulley built on the stiffest cage on the market.
Besides reduced friction, this cage is built with shifting accuracy and chain retention in mind. Also, oversized pulley systems are an excellent way of reducing the additional friction caused by clutch derailleurs.
