>>1142636Well, there are fucktons of different types of aluminium.
Your can is made to be soft, there is no need of it to be strong like a frame. It only contains a liquid. Some brande make cans of transparent PP due to this fact.
From serial 5000 - 6000 to 7000 they all have different hardness, weldability and machining ability.
The smaller the number the "softer" the aluminium is (like 5000 serial is softer then 7000)
In bicycle frame design sometimes not all the tubes are used in the same grade to get some stiffness where required and softness for comfyness. (i'm of coursenot talking of chinese frames where all the tubes are the same)
In the industry we even sometimes weld with a softer grade of aluminium apport on a frame to prevent it from cracks.
By then: aluminium can snap, but on MTB or Track frames there are big warnings to this: cracks. Check the frame before a ride and there won't be surprises.
Whereas carbon, even if you check the goddamn thing, it can snap by surprise because the cracks are way too small to be seen by the eye only.
This is my personnal experience why 2nd hand carbon frame = no thanks.
>>1142539well anon, i think there is lots of info missing, this frame looks like lot of info are missing: no geometry, size of the frame is a no go for me.
It looks like a "polo bike" frame by the looks.
I know these tubings, they are quite heavy too.
And most important when buying overseas, think of import duty, i once paid on a 300$ shippement value 200$ of taxes + 100$ shiping so... i'd rather not go for this one.
