Hey Ya'll, I just bought a Giant Anthem 1 and want to upgrade the stock Huthinson piranahas to something from the Conti supersonic (400 grams per tire) line, either an explorer or am really liking the looks of the 2.1 speed king. Like anything in life there has to be a trade off of durability versus weight so can I expect the supersonics to hold up for every day riding? How about the speed king line, any one try them yet? I have the explorer upfront on my Trek so know what to expect there. Thanks for any input.
