Preccc

I have two choices: http://www.rocknrollbikes.com/trials/complete/onza-zoot-2012-24-street-trials-bike.html or http://www.adverts.ie/bikes/onza-trials-bike/1614540 . I can't find t-rex specs/reviews (although this one is custom). I'm looking forward for buying t-rex because of having set of gears (I know it's trial, but still would have to change places to jump)
