Finish Line's Mineral Oil Brake Fluid is far from your basic, common mineral oil - Finish Line spent some time in the lab and developed a 'high performance’ mineral oil for use on Shimano and Magura systems.
Finish Line's Mineral Oil fluid is formulated specifically for bicycle brake systems and feature no compromise, leading edge chemistry to provide superior fluid life and braking performance.
Featuring a super low viscosity to yield superior lever response, pad retraction, and consistent performance through a full range of operating temperatures.
What else is there to say when a 50cc bottle if the shimano stuff is three times the price!!!
