Almost all riders suffer saddle soreness at some time in their careers. And its not just the 200km a day people who have to take precautions - even 20km can badly affect some people.
Keywin's John Winkie was one of the sufferers on over 50km rides and he set out to find a solution. In conjunction with some very clever chemists, John set new standards with Shammy Cream some 20 years ago and the formula remains very similar today. Before Keywin, creams had varied from axle grease to sump oil depending on temperature. Keywin stabilised the cream through all ambient temperatures. Some actually rotted the shammies of the day - think what they did to your skin. When the creams failed riders resorted to methylated spirits and other even more home spun remedies.
But by carefully mixing additives to the stable base of lanolin (derived from wool processing - and who has more sheep than New Zealand?) to give antiseptic and anti fungal properties, Keywin Anti Chafing Cream provides the best possible protection from soreness. Many other Creams have tried to emulate Keywin Anti Chafing Cream but all have fallen short.
Keywin changed the name from Shammy cream to Anti Chafing Cream when other sports people experimented with great success for other chafing problems like runner's nipple and wet suit collar sores.
