i have had a go on my freinds onza zoot i found that they are great fun to ride it was good because going from my 20 to his 24 was a good experience because you have more to chuck around
yh i have got an internal hope headset but the cups dont fit as they are to deep so i also have a normal echo headset in my shed so i was thinking that it might be cheaper to buy an adapter than what it would be to buy a new headset cheers Simon
