Hello, well I have recently cracked my Onza limey 3 near the hole where the cable comes out. It's really not a big crack so I can still ride and pull big moves, but I could feel this would happen with my riding "style" and I could feel the bike was too fragile for me. So I am considering changing my frame and getting a brand new one for Christmas! (I know, it's along time away butI need to know early...) After research on all possible websites, I have decided to go for the ZOO! Piranha frame. The geo is the same than my previous frame(except the longer chainstay) and I know CLS was riding on ZOO! ( so it's solid?). As I am only riding street trials, I have several questions: Is that frame solid, and can I trust it? Has anybody heard from a breaking ZOO! Piranha frame? I am running rear vees, so would I need to buy a brake booster too? Would my fat (but so good) DER KAISER 2,5" tyre have enough room? I use to be with horizontal dropouts on the Onza so I need to know if it happens that you break your chain tensioner? If yes, how often? I heard that bikes with horizontal dropouts have not the same pedalling response as vertical dropouts frame due to the chain tensioner,is it true? If yes, why? Last question for people who owe or who owned a Piranha frame: How long have you had it for? What are your opinions on this bike? Thanks in advance for all your answers! EDIT : Found this: http://www.trials-forum.co.uk/forum/index....;hl=ZOO+Piranha so perhaps I would go a Gu Typhoon! Same questions! Sorry about that!
