I googled litespeed after my unicoi cracked at the weld attatching the chain stays to the down tube and was told that my "lifetime warranty" did not include "wear and tear"---this bike is four years old, i am 51 y.o. 170 lb cc rider whose idea of wonderful is smooth slalom and my rare max air is 1-2'.....DO NOT BUY the lifetime warranty BS. They are offering "a replacement at cost" but i plan to invest elsewhere
