I beams are stiff but they don't have much weld area on the end so surely that would make it easier to snap the headtube clean off the frame??

Proof is in the pudding so to speak. How about a radical idea?????????? We decide once its been tested to pieces how long it lasts, as opposed to judging its strength on looks and hearsay. Onza make and sell bikes. Must of us dont. They know more abut what they are doing that the vast majority of the people on here. This thread has also brought out from the woodwork certain members who evidently dont know anything about bikes, as well as those who do. I guess some people are always going to be a misplaced hammer in the sharp knife draw.

"Argh noes its got 2 wheels its a copy"

Sounds stupid but thats basically what a lot of people in here are saying. When building a bike frame your pretty limited design wize think about it the headtube, dropouts, bb shell all have to be in near enough the same place theres only so many ways to join them up.

Would you rather onza made a frame that was 'different' and fell appart in 2 seconds? Maybe have one chainstay because its not been done? Theres no point in being different just for the sake of being different. It looks like onza are taking concepts that weve all seen used before and taking their own twist on them and trying to improve upon them. If no one used other peoples concepts we would still all be living in caves.

Look at the t-pro for instance? It was very similar to the old koxx levelboss but improved upon it with a different downtube and a few other tweaks. People seam to class bikes like the t-pro as a budget bike but really they are the same quality and spec as koxx bikes etc costing double the price. Afterall half the components are made in the same factory.

Sure in the past onza made some bikes that broke but who didnt? Looking back 3-4 years or more every single Echo ES2/3/4 broke yet everyone seams to have forgotten about that? Look at their latest frames they are very much so just as good if not better than the competition.

As somebody has rightly pointed out, the frame is nothing like a Zoo Python. OK, it has CNC side plates but so have many frames. I am over here designing and discussing many things with our suppliers and also frame designs with our many manufacturers. This frame was put together to look at and address some ideas and was nothing more. The central CNC plates were braced in the middle with the horizontal tube as some others have pointed out, because it has no seat tube. Most of these ideas are attempts to increase the stength and stiffness of the frame and improve the braking power. Very few go into production but they are building blocks on the way. Lots of the ideas we throw around over here will come to fruition later in the year and I like to see all the controversy something like this brings up but some of you should really lighten up.

Exactley.

Koxx headtube, zoo seat-tube arrangement? The onza's design in both those departments is CLEARLY differant, it may be based upon the same principle, and from a distance may look rather similar, but I think that 'second bottom bracket shell' might just have a good chance of being a good idea. It allows there to be an absence of a seat tube, while still maintaining stiffness where it is needed.

Mike, do you's tend to design a few (similar) frames in a CAD package, run a few test's and then make a prototype out of what look's to be the best, or is it a case of making a prototype out of an idea using simple working drawings?

Anyway, isn't it an improvement on the older T-mag? That's one bike i've never liked.

This topic is GAY GAY GAY.

i wanna know why this forum gets clogged up with shite!!

it's full of people that think they know everything IMO!

'that frames gunna snap there, there and there.' <--------wtf!!! you can't work out that kinda stuff from a couple of pictures :o

:angry:

But you can determine the weaker points of a frame if you know what to look for........

It's why I want to see some stress analysis of it, while it won't be 100% accurate, but it will give an idea of where the frame is likely to fail, and (less accurate again) what sort of forces will be likely to produce failure.

but why do people want to even highlight these problems if the bloomin frame is in it's prototype stages :S

argh
