-2ºC to -8ºC (28ºF to 18ºF). CH7 is a good general purpose pre-wax and travel wax because its range for use falls in the middle of the Cera Nova system. CH7 makes a good base bonding wax for either warmer or colder waxes applied later. For summer and glacier skiing and riding it provides good glide plus good base protection especially when mixed with CH3. Recommended iron temperature setting of 135ºC.
