dont listen to him... danny you rode my bike when it was feeling shite, if i remember rightly the brake was awful and probably a few other things... and you cant say you would rather have a frame which you have never rode both ride nice, i would rather have the zenith because i ride one... all depends on the set up and components... i have used a mad high rise and long stem which makes it beast for taps, and iv used an echo low stem which rides better for gaps... which i thinks good that you can use either one and it will make it ride differently... although you dont really want two stems (i just happen to)... so ignore all of that and buy a stem thats somewhere inbetween maybe i think the wheel base is pretty similar (only differs by 10mm????) but the bb rise on the hifi makes it feel shorter... the zenith feels just right for me and i like how it is very rigid/stable on the back wheel. if thats helped Jonny
