Replacement Carbide Flextip as fitted to most models of LEKI poles. Overall Length: 80mm. The Flextip is designed to grip on all but the hardest smooth surface thanks to its hollow point Tungsten Carbide tip. It is called a "Flex" tip due to its ability to withstand a bend of up to 30 degrees about its mid section if it gets stuck in a crack. If bent further then it may snap, but in such a way as to prevent damage to the pole section allowing the section to be re-used.
