Excellent as a high performance training wax, Swix Cera Nova LF8 Red Fluorocarbon Bulk Wax. Also, the high base penetration characteristics make this wax a good choice for keeping the base in optimal condition. For racing, we recommend using Cera F, LF8, as the final layer within this temperature range. LF stands for Low Fluorocarbon. These are fluorinated hydrocarbon waxes having a low percentage of low-melt point flouro additive. They are used as training waxes, or as racing waxes with Cera F as a final layer, or alone as a race wax at very low temperatures. The temperature ranges and wax colors of the LF waxes coincide with the HF category, however they are distinguished from the HF waxes by the 60 gram or 180 gram bar size. The LF waxes can be distinguished from the CH waxes by a slightly more transparent look.
