Free-range, organic brake pads.
Formula recommends their Organic Brake Pads for general XC use and for riders under 170 pounds (77 kilos). Organic brake pads offer minimal break-in period so you can get on them hard, and they will perform at their peak after just a couple rides. They also give you solid modulation and consistent performance when used for relatively dry riding. Formula's Sintered Metallic Pads are a better choice for heavier riders, folks using their bikes for freeride or DH, or riders in moist climates.
