Well i did have a zona zip, and i loved it at first, improved my sidehopping so much, but i then got bored of it and decided to spray it matt black, still it did not make me want to ride the bike anymore, i have now gone for a ko-bike km1 (see Trials-Uk for more details), i will post a review on here after i have rode it for a while. Me personally though, i would not really advise the zona, it just gets boring, for some strange reason everybody sells them after a while. Dan.
