Frixa brake pads are a UK designed quality performance pad designed with passion to create a long lasting, more advanced replacement for the genuine, often cheaply made brake pad. Available in soft, medium and hard. Choose soft for cold, wet or winter conditions up to around 10c. Medium is suitable for temperatures of 10-20c with hard being designed for them really hot UK summer days or high temperature countries. These will fit the current Freeline brake systems as used on Compkart and Birel ART karts.
