Transfil is a quiet giant of a company. Suppliers of control cables to the French car industry, Transfil also produces inner wires and outer cables for bicycles. The original gear or brake K.ble sets were surpassed by the more upmarket Black Snake compressionless system with a Teflon coated jacket, resistant to water, mud and sand. Then followed the Flying Snake with watertight carbon/ Kevlar outer casing weighing 30% less than the K.ble set. The very latest Nox Snake has a white carbon outer casing with Teflon coated inner tubing. These sets are MTB or road bike compatible.
