don't get so ratty about it mate, i was just saying, i have seen some peoples bikes, koxx inperticular and they have been ragged, they mainly crack on the chainstays, i land on my chainstays alot and land hard on the bash alot too, if you saw my riding, you would agree with me that a koxx levelboss would not stand up to the abuse that my tpro has... oh and what year was your mates tpro??
