I've never ridden a 3C Compund on any maxxis XC tire. I mean, is it worth it though? Right now I'm using an Ardent 2.25 EXO/TR on the front and an Ardent Race 2.20 EXO/TR on the rear. I'm one of those people that don't really like the little more upgraded versions of themselves of I could say, I don't really know what 3C really does. Well we all can tell that it says "MaxxSpeed" so it'll obviously boost it's rolling speed. But, is that it? Am I missing something? I'm not really into upgrading stuff on my bike (plus I'm just 15 so I'm broke) but when I do need to change or upgrade something I want the best. Especially if it's gonna make my XC bike more efficient. Any thoughts? Let me know.
