Mine is a 20'' and I'm about 6'3'' and running a 100mm stem at the moment. My understanding is that the sizes are pretty similar to the Kona range as its more akin to my 20'' Kona than my 19'' 😆
With regards to failures these were hardtail related. If you search on here I asked a similar question a while back and a chap from Sideways cycles clarified this.
I have complete confidence in mine. I weigh 100kg and ride reasonably hard…but I guess any frame can break.
letmetalktomark cheers i'm 6"1 and used to ride an 18" Coiler with a reasonable amount of seatpost. I suppose the Canzo's much more XC really and so am I to be honest:)
What shock has yours got? Can't see pics here. How long have you had it? What forks do you run?
They don't break any more or less than any other frames really – so don't let that put you off. If it's used you've got no warranty, so get it bought and enjoy it.
