    New question here. Aluminium frame and weld - is this OK?

    Hello there! I am newbie in bike world, recently I bought Cannondale Trail SL3 (2013 year). This bike amazes me, good paint colors, good frame, quite good hinged equipment. I hope it will be good experience and good bike for my first serious bike.

    I have a question to you. There is a fragment of top tube, seat tube and top stay on the photos below. The left side and the right side. You can see the welds in the red rectangles.

    As you can see, the welds are quite different. On the right side it looks like thick seam, so on the other side the seam is more smooth. So I thought that both of seams must be similar, but we can see other case. Does it matter and can I get some troubles like cracks in the future? Does it matter for the mechanical strength of the nodes? I mean, is it a production defect or something like this or just "don't worry and go ride"?

    Nothing to worry about, that's what Cannondales look like now.
