In all seriousness; If you’re this unsure about why a frame is built like this, why are you building a bike from scratch? You’d be better off buying something complete and going from there…
I’m not trying to make fun of you, just attempting to save you from further embarrassing thread creations…
Im not sure if this is a ‘Punkd’ style joke… but being that the members id is ‘morganfreeman’… and the bike is black… just sayin… maybe the frame needs a decal on it naming it the ‘morganfreeman’…
perhaps morganfreeman likes his couches with interesting patterns, to ponder lifes questions while sitting on
And this thread is the reason I hang around on these forums.
But back to the topic, I had a couch like that once upon a time. I found by regularly turning the cushions I created a much better sitting environment from the displacement of the stuffing.
