one piece?

[T-naks]

what are the advantages or better things about having one piece bars instead of other ones?

 

[Zaηe]

no stick out clamps/bolts, one solid piece, looks better, stronger, no constantly having to tighten things, more designs.
im sure others have more to add.

No wobble, you can get wider bars

 

[Zach!]

you can get wider bars and you dont have to use 2 clamps

i like 2 piece bars better than one piece

Good thing about 2 piece bars is you can change the crossbar sizes...

You can change the cross bar sizes on one pieces, you just can't really put it back if you don't like it....
