Sorry to burst your bubble...
Mmy Friend and I both purchased 2004 Tirades within two months of eachother, and we both putour tirades through some fair abuse, but trust me, I know these bikes. My Tirade pedaled like crap, barely ever shifted correctly (due to poor chainline issues which are nearly unfixable), the rims both severly flatspotted, I blew out the rear suspension linkage twice, and the seat broke within one month. The best part was the brakes though, one mud run and they were pretty much shot forever. My friend had better luck, the only part he broke was the brakes and the seat, that is, untill his frame snapped at the poorly engineered seat tube/shock mount junction.
TIRADES SUCK, that's why they aren't produced anymore (k2bikes.com)
