I recently bought the sl7 Ex preset and have been using it for Dragon Ball and other things. I got a water bottle cage today so I'm assembling it, but even though I'm using the right size hex wrench and tightening it to the proper torque, 2 out of 4 bolts stripped;; I searched online and found out that they are originally weak, but I didn't know they were that weak haha~ It doesn't seem like a big deal since it's only the last two after everything else is assembled, but it might be a problem when I have to take them out later,, Well.. future me will figure it out.
